It is necessary to pay special attention to the above-mentioned positive film at the crystal where it is sufficiently rigid.晶晶=:it takes a thickness of 1〇〇"m and has sufficient rigidity - the two cones 5 clips one will use the edge with a tapered wall' to keep the outer periphery of the wafer, this cone is supported by the cone wall to support the periphery of the wafer Above the wafer, "between the students, the wafer is held by the attraction. As mentioned above, the thickness of the wafer side is held by the edge of the wafer and the vacuum is attracted to the surface of the wafer.] = The wafer with lower conductivity may be deflected and damaged. Use a flat collet having a flat surface and contacting the flat surface to the side of the wafer. Since the cone clamp is only in contact with the outer periphery of the wafer, even if some foreign matter is present on the crystal, no damage is caused. Since the plane is in contact with the wafer, if there are foreign objects or fragments of the wafer on the wafer, the wafer will be chipped between the wafer and the tube, which will increase the risk of damage on the wafer. Especially in recent years. Thin and technology-friendly wafers have a tendency to cause damage to 7 1335051 due to their lower rigidity. Moreover, the prior art discloses a technique of blowing foreign matter by blowing air, but blowing away the difference If the object adheres to the flat collet, the size and frequency of damage to the highly rigid wafer will not be damaged, and the wafer with low rigidity will be damaged. In addition, in order to fully remove the foreign matter, consider strengthening. The blowing method of the air supply, but if the air supply is too strong, the wafer itself is blown away. As described above, the technique of picking out a flexible and low-rigidity wafer of the prior art is still insufficient. The invention provides a bonding apparatus capable of further sufficiently removing foreign matter for picking up a wafer. The bonding apparatus of the present invention is characterized in that: a wafer ring is attached to the expansion film for holding the completed wafer. a wafer to be cut; an upper stage having a top pin on top of any wafer on the wafer ring at a predetermined timing; a flat collet for attracting and transporting the wafer by the top of the upper pin, and The wafer is flat relative to the surface; the static eliminator is used to supply ionized gas around the wafer-cut wafer and the planar collet on the wafer ring, and the blower , is disposed in the vicinity of the flat collet, and blows the ionized gas to any of the upper top wafers only before the top top time point. π and 'the joint device of the present invention is characterized in that: the wafer ring is attached On the expanded film, the wafer for maintaining the wafer cutting is completed; the upper stage has a top pin on any wafer on the wafer ring at a predetermined timing; the flat tube is used for attracting and transporting The upper top pin top = the 曰曰 piece 'is flat relative to the wafer; the & electrical appliance is used to supply the ionized gas 8 1335051 body to the wafer and the flat collet to complete the wafer cutting on the wafer ring, and The blowing mechanism is connected to the flat collet, and the ionized gas is blown to any of the upper top wafers only before the top top time point; the flat collet has a hole opening in the flat surface through which the decompression attraction of the attracting wafer is attracted. Switching is performed between blowing ionized gas to the wafer. Further, in the joining device of the present invention, it is preferable to provide a duct </ RTI> disposed near the flat collet for attracting a gas ionized by the blowing mechanism and the static eliminator. Moreover, the bonding method of the present invention uses the following elements to be attached to the expansion film to maintain & the wafer to be finished, and the upper stage 'has the wafer at the same time point The top top of any of the wafers on the ring, and the flat collet, are used to attract and transport the wafer on top of the top pin, which is flat relative to the wafer; the feature is in the package a step of actuating the degassing stomach (for supplying ionized gas around the wafer and the flat tube of the wafer on the wafer) before the bonding; the blowing step is performed at the picking position of the flat collet Μ sending ionized gas; the topping step is performed by the person who ionizes the gas...I's the wafer from the expanded film toward the flat top; and the picking step, the wafer is picked up by the 十-faced ten-face collet. According to the above configuration, since the Dalker delivery mechanism is disposed (disposed in the vicinity of the flat collet, the ionizing gas is blown off by any wafer on the top of the top only before the top top point), In the state where the wafer is easily attracted by the 沣斟曰 沣斟曰 h ~ Xiao Yu Qian Qi Qi folder, it is impossible to blow the gas to the 曰 片. According to this, only one 曰w T prevents the blowing gas from blowing away the wafer, and only the foreign matter around the day piece is taken. Also stop the static electricity when blowing. 1 body ionization 'can prevent 9 曰 and 'Because of the de-energizer (for the wafer on the wafer ring and the flat collet π into the daily cutting jEg, ^ supply ionized gas), it can be The wafer and the wafer on which the wafer is cut are attached to the wafer on the 曰m ¥. "H power to prevent blow-off of the differential power-off takes a few seconds. By ... = sub-gas will be short between the devices, so it is better 4, when the use of the pick-up cycle is more than the supply of the body when the power is removed. ^ Use. Loading, continuing to ionize the gas. The flat collet has a hole that opens into the θ κ Mn surface, and the hole can be cut between the second attracting and the ion blowing gas to the wafer. Turning h(4)h on the top of the pen, etc. Further, the gas is blown from the wafer in the opposite manner to the ionized gas of the wafer, so that the foreign matter under the flat collet can be removed with higher efficiency. Since the duct is disposed near the flat collet ( In order to attract a gas that is ionized by blowing, a mechanism, and a device for removing electricity, it is possible to efficiently concentrate and eliminate foreign matter blown away and foreign matter removed by electricity removal. Further, according to the above configuration, first, in the joining operation, The de-energizer starts to act 'follow' to blow the ionized gas near the wafer. After the end of the blowing, the wafer is topped up and picked up by the flat tube inflammation. According to this, sufficient de-energization time can be ensured 'the foreign matter is blown away from the wafer, and [Embodiment] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

The top action is to top the upper table 16 so that it approaches or contacts the underside of the expanded membrane, and then the top pin 18 is topped up. Alternatively, the upper stage 16 may be fixedly disposed at a position close to the expansion membrane 14 and then the upper top pin 18 may be topped up. The upper top pin 18 is moved up and down along a guide member provided above and below the upper table 16. The position at which the upper top pin 18 moves up and down is the so-called picking position at which the wafer 20 is picked up by the clip 20. That is, the vertical movement axis of the pick-up position of the upper and lower moving shaft end clamps 20 of the top pins 18 of the upper tops 8' is disposed coaxially with respect to the collet. Under the function of the top processing module 88 of the control unit 8A, the top top 18 is driven up by the top top actuation II 72 in accordance with the program control timing described later. A piston or the like can be used as the upper top actuator 72. The collet 20' has a function of picking up at a pick-up position and sucking and holding the wafer: and transporting it to the next work position*, for example, a function of adjusting a wafer tilt or the like to a predetermined position such as a bonding position of a die bond on a circuit board. . The collet 20 has a holding portion for holding the wafer 8 at the distal end portion, and a through-opening of the cylindrical member 13 1335051. The through hole 22 is connected to the suction portion 60 (the valve 64 and the vacuum source 62 are arranged in series). ). Under the function of the pickup processing module 90 of the control unit 80, the collet 20 is driven to move by the collet actuator 74. A χγζ drive motor can be used as the collet actuator. In particular, the drive collet moves up and down at the picking position. Namely, the collet 20 is driven to move in such a manner as to be lowered toward the wafer 8 which is topped by the upper top pin 18, sucked and held by the leading end portion, and raised again, and the wafer 8 is peeled off from the adhesive film 14 having adhesiveness. Fig. 2 is a bottom plan view showing the collet 2 opposite to the wafer 8. The bottom surface of the collet 2 is a flat surface, and the through hole 22 is opened at the center thereof, and a plurality of radial shallow grooves 24 are provided from the through hole 22 toward the outer circumference. Therefore, at the pickup position, the collet 20 is lowered to contact the wafer 8, and when it is attracted by the suction portion 60 connected to the through hole 22, the flat surface of the bottom surface as a whole contacts the surface of the wafer 8, through the through hole 22 and the groove 24. The wafer 8 is attracted. As described above, the collet having a flat surface on the bottom surface and contacting the entire surface of the wafer 8 and sucking and holding is called a flat collet. By using the flat collet, when the wafer 8 having low rigidity and flexibility is processed, the wafer 8 is attracted by vacuum, so that it can be attracted without being deformed. The static eliminator 30 includes a pressurized gas source 32, a static eliminator 34 (ionizer), and a nozzle 36' that supplies the ionized gas to the wafer and the collet 20 on the wafer ring 12, and removes the ionized gas. The function. Under the control of the static elimination operation processing module 82 of the control unit 80, the operation of the static eliminator 30 is controlled as follows. For example, when the collet or the wafer ring η or the like generates static electricity for some reason, the static electricity system combines the neutralization and the like, and the ionized gas generates an electrostatic charge. 1335051 The gasification of the device or its components by electrostatic discharge takes several seconds. As described above, since the static elimination time required for the elimination of the ionized gas is longer than the period of the joining operation, the ionized gas supplied from the static eliminator 30 is supplied at a low speed, but it must be continuously supplied. Therefore, after the "coupling device" is turned on, the neutralizer 30 starts to operate before the joining operation, and the ionizing gas is continuously supplied at a low speed. The blowing unit 40 is configured by connecting a Garley gas source, a valve 44, and a static eliminator μ' 2 48 in series, and has a function of blowing the ionized gas from the nozzle 48 to the surface of the second sheet. As described above, when the wafer 8 is separated by using a suitable separation jig, a fine chip or the like is generated. Or, because the 狁曰H e main 隹 day 0 piece 8 surface. The blowing portion 40 has a function of blowing away the surfaces of the two sheets 8. A dry compressed air compressor or the like can be used as the description of the valve 44 of the blow-in portion 40 of the pressurized gas source 42β I, and the pumping processing mold of the control unit 80 can be used. And the control of 86 is carried out, whereby the pressure, the pressure, and the pressure are 4 昜; "the main control ionizing gas is blown in a timely manner. The flow rate and the flow rate of the foreign matter adhering to the surface of the cymbal 8 can be sufficiently removed. : The surface of the wafer 8 itself is ordered by the expansion of the wafer 8 in order to maintain the adhesion of the crystal without being blown away. The cycle time of γ and the top of the 曰 曰 8 is very short. For example, the splicing is about seconds. Even in this short time, ^, the blowing time is about U. From the airflow source of the house milk source 42, the attached foreign matter which is attached to the wafer 8 with a strong monthly density of 8 can be sufficiently removed. 15 1335051 The static eliminator 46 has the same function as the static eliminator 34 of the static eliminator 30. , a device having a function of ionizing a blowing gas. As described above, in general, the blowing gas system uses a dry gas, but if it flows at a large flow rate, there is a problem that static electricity is generated in the wafer 8 and the collet 20, etc. Therefore, a static eliminator is used before blowing the pressurized gas. The ionizer is ionized. The static eliminator is always in an active state regardless of the point of blowing. Since the ionization of the gas itself is instantaneous, the static electricity caused by the blowing of the pressurized gas can be prevented. The gas supply path for restricting the blowing direction of the ionized gas is constituted, for example, by a tube or the like. As described above, the wafer ring 12 moves in a plane at the pickup position, but the collet 20, the upper pin 18, and the top wafer 8 are moved. Since the plane position does not change, the tip end of the nozzle 48 is disposed so as to face the surface of the wafer 8 at the pickup position. Further, the tip end of the nozzle 48 is disposed so as not to interfere with the plane movement of the wafer ring 12. It is disposed approximately 10 μm above the wafer ring 12, and the front end of the nozzle 48 can be disposed in such a manner that the plane is approximately 1 mm from the center of the plane of the upper pin 18. The blowing timing is controlled as follows: that is, the wafer ring 12 is driven to move, and then, after the wafer 8 to be picked up is positioned at the pickup position, the surface of the wafer 8 is immediately blown by the function of the blowing portion 40 for about 〇1 second. After the end of the blowing of about 0.1 second, the upper top pin 18 is driven to advance the top, and the wafer 8 for removing foreign matter or the like by blowing is directed toward the top of the collet 20 (that is, only before the top time point). As described above, the blowing portion 40 has a configuration similar to the static eliminator 30, but not 16 at the same point that the power supply H 3G supplies a low-speed ionized gas, and requires a certain amount of time to turn the wafer ring 12 and the tube. In contrast to this, the blowing unit 40 blows the foreign matter adhering to the wafer 8 and the like to the wafer 8 in a short time. In other words, the static eliminator 34| of the static eliminator has a function of generating an ionized gas for removing electricity, but the static eliminator 46 of the blowing unit 40 has a function of ionizing the gas in order to prevent static electricity from being blown by the blowing gas. The guide roller 50 is provided with a vacuum source 52 and a suction duct 54, and has a function of collecting and discharging the gas ionized by the static eliminator 30 and the gas ionized by the blowing unit 4 。. Preferably, the suction duct 54 is disposed such that the pickup position is centered on the opposite side of the nozzle 48 of the blowing portion 40 in a substantially symmetrical positional relationship. In addition to the side wall opposite to the front end of the nozzle 吹 of the blowing portion 4, a suction duct 54 is also provided at the top and bottom portions.

The openings in the side walls and the bottom portion recover the gas blown to the surface of the wafer ring 2 by the blowing portion 4, and the openings in the side walls and the top portion recover the gas ionized by the electricity. The function of the bonding apparatus 1B configured as described above, in particular, the functions of the control unit 80, will be described using the flowchart shown in FIG. The flowchart of Fig. 3 shows the flow of each processing procedure of the pickup processing of the bonding apparatus 10. After the power is input to the bonding apparatus 10 and initialized, the operation of the power-removing processing module 82 of the control unit 8 starts the operation of the static eliminator 3 (s1). This is done first before performing a specific joining operation. The specific cooperation is the following S12 to S20. The reason for this is that the static eliminator 3 is a wafer that is subjected to wafer dicing on the wafer ring 12 by ionizing gas, and a 13 1335051 eliminator, but as described above, it takes time to remove electricity. When the engaging device is turned on, the operation of the neutralizer 30 is continued. Accordingly, the components of the docking device 10 are continuously supplied, in particular, the wafer ring 12, the collet 2, and the like are supplied with the chemical gas, and the constant is maintained in a state where the power can be sufficiently removed. Further, since the ionized gas is sucked by the duct portion 50, the foreign matter adhering to the wafer ring 12 or the collet 20 due to static electricity is peeled off by the static electricity, and is discharged to the outside together with the ionized gas by the duct portion 5〇. The activation of the conduit portion 5 can be initiated at the same time as the activation of the deaerator 30, but must be initiated prior to the specific splicing operation. From the start of the operation of the static eliminator 30, after a sufficient time required for the static elimination, for example, a few seconds, a specific bonding process is started. Here, first, the wafer 8 is positioned at the pickup position (si2) by the function of the positioning processing module 84. That is, an instruction is issued to the collet actuator 74 to move the collet 2G to the pick-up position as described above, and the pick-up position is the position of the top pin 18, whereby the collet 2 is moved to oppose the upper top pin 8 Towards the location. Next, an instruction is issued to the wafer ring actuator 7G to drive the wafer ring 12 to move so that the wafer 8 to be picked up reaches the pickup position. Accordingly, the wafer 8 to be picked up is positioned below the collet 20 and above the upper top pin 18. After the positioning, the valve 44 of the blowing unit 4 is commanded by the function of the blowing processing module 86. In the above example, the ionized gas is blown to the surface of the wafer 8 in about ten seconds (S14). In the above example, the pressure of the ionized gas is several atm. According to this, in the state in which the wafer 8 is stably held by the adhesiveness of the expanded film 14, foreign matter or the like adhering thereto can be blown off and discharged to the outside together with the ionized gas by the conduit portion 50. In addition to the 18 1335051, the wafer ring is de-energized by the action of the neutralizer 30, so that the foreign matter blown away, etc. will not be owed again, and the filling knife will not be attached to the wafer ring 12 by one person. The wafer to be cut, the collet 20, and the like are attracted by the duct portion 5A. After the blowing of the temporary time, the upper top wafer 8 is then carried out by the command of the upper top processing module (2) to actuate a, and the upper top wafer 8 is performed (S16). Accordingly, the wafer 8 is easily separated from the expanded film. Receiver, by picking up the function of the processing group 90, releasing the collet actuator % and the attraction portion (9)
:曰二…0在拾取位置下降,將上頂、容易剝離的晶 14 Λ面整體吸引保持’並再次上昇,將晶片8從擴張膜 ^離並拾取(S18)。接著,將晶片8搬送到接合位 置 進行晶粒接合(S20)。 β接著,判斷位於晶㈣12上之應進行接合的所有晶片 8是否已完成接合(S22),當判斷尚未完成時,回到si2 , 進行下-個晶片8之S12至S20的處理。當判斷所有晶片 8的處理完成時,除電H 30會停止作動(S24)。導管部 5〇的作動亦會同時停止。 如上述,在持續進行除電的狀態下,僅在將晶片上頂 並拾取之前,以短時間、較強氣流之方式對晶片吹送離子 化氣體,藉此,相較於習知,能更有效將附著於晶片之異 物等除去,防止其再次附著於筒夾等。據此,可防止進行 拾取時異物等位於晶片及平面筒夾之間防止剛性較低、 容易撓曲的晶片等產生損傷。 (實施例2 ) 上述中,分開設置吹送部與筒夾,但利用筒夾的吸引 19 丄 丄 孔’能在吸引保持晶片前從筒失前端對晶片吹送離子化氣 體。圖4係表示將開口於平面筒夾之平坦面上的孔分為吸 引用’、人送用的接合接^ 1〇〇之構成圖。與圖"目同的元 件附加相同符號,以省略詳細說明。 〃圖4中,與圖!的接合裝置1〇之構成的不同點在於: 筒夾及吹送部’此接合裝置1〇",筒夾2〇之貫通孔22 不僅用以吸引晶片8’亦用以對晶片8表面吹送離子化氣 體。 再者,用以吸引保持晶片8的真空源62及閥64的吸 引系列線、及用以對晶片8吹送離子化氣體的加壓氣體源 42、閥44、及靜電消除器46的吹送系列線,皆連接於切 換部66,構成吸引吹送部26。由控制部8〇控制吸引吹送 部26的2條系列線連接於吸引孔的時點。 如圖2之說明,貫通孔22係開口於筒夾底面的平坦面 中央的孔。貫通孔22連接於吸引吹送部26的切換部66。 切換部66具有選擇將吸引系列線或吹送系列線連接於貫 通孔22、或使二者皆不連接而成為敞開端,即敞開於大氣 壓的功能。 使用圖3說明切換部66的選擇。在si〇的除電器作 動步驟中’貫通孔22會敞開於大氣壓。當進行si】的定 位步驟時,貫通孔22亦會敞開於大氣壓。 於S14的吹送步驟中’貫通孔22連接於吹送系列線。 即,加壓氣體源42、閥44、靜電消除器46的系列線連接 於貫通孔22,如圖3之說明’藉由控制部8〇的吹送處理 20 1335051 模組86之功能控制閥44,較強氣流的離子化氣體在短期 間内通過筒夾2G的貫通孔22,吹送至晶片8表面。上述 之例中’短期間係0.1秒,較強氣流係加壓氣體源42的壓 力為數atm。在吹送步驟後的S16之上頂步驟中,貫通孔 22會敞開於大氣壓。 於S18的拾取步驟中’貫通孔22連接於吸引系列線。 即,真空源62、閥64的系列線連接於貫通孔22,如圖3 =說明,藉由控制部80的拾取處理模組9〇之功能,通過 筒夾20的貫通孔22吸引保持晶片8。在s2〇的接合步驟 中:當搬送晶片8及進行晶粒接合時,貫通孔22會與吸 引系列線連接’接合結束後,貫通孔22會敞開於大氣麗。 如上述,將對筒夹之貫通孔之連接在大氣壓、吹送系 列線、吸引系列線之間做切換n,吹送步驟與吸引步 驟不會重複〇因此,當進行吹送較強之離子化氣體時,不 會進订上頂與吸引,不會因進行吹送而吹走晶片。又,由 於透過筒夾的貫通孔從晶片上方進行吹送,故可進一步高 效率除去筒夾下方的異物等。據此,可進一步有效防止異 物位於平面筒夾的平坦面及晶片表面之間。又,不需要設 置用以吹送的特別噴嘴。 【圖式簡單說明】 圖1係表示本發明之實施形態之接合裝置之拾取處理 所必要部分之構成。 圖2係本發明之實施形態之接合裝置所使用之平面筒 夾之仰視圖。 21 1335051 圖3係表示本發明之實施形態之接合裝置之拾取處理 之各處理步驟之流程圖。 圖4係表示其他實施形態之接合裝置之構成圖。 【主要元件符號說明】曰2...0 is lowered at the pickup position, and the upper and the easily peeled crystals are sucked and held as a whole, and rise again, and the wafer 8 is separated from the expanded film and picked up (S18). Next, the wafer 8 is transferred to the bonding position to perform die bonding (S20). Then, it is judged whether or not all the wafers 8 to be bonded on the crystal (four) 12 have been joined (S22), and when the judgment is not completed, the processing returns to si2, and the processing of S12 to S20 of the next wafer 8 is performed. When it is judged that the processing of all the wafers 8 is completed, the neutralization H 30 stops the operation (S24). The actuation of the catheter section 5 will also stop at the same time. As described above, in the state where the static elimination is continued, the ionized gas is blown to the wafer in a short time and a strong gas flow only before the wafer is topped and picked up, whereby the wafer can be more effectively compared than conventionally. Foreign matter adhering to the wafer or the like is removed to prevent it from adhering again to the collet or the like. According to this, it is possible to prevent damage such as foreign matter or the like which is located between the wafer and the flat collet during the pick-up, and which prevents the rigidity from being low and easily deflected. (Embodiment 2) In the above, the blowing portion and the collet are separately provided, but the ionizing gas can be blown from the leading end of the cylinder before the suction and holding of the wafer by the suction of the collet. Fig. 4 is a view showing a configuration in which a hole which is opened on a flat surface of a flat collet is divided into a suction reference and a joint for use by a person. The same symbols are attached to the same elements as in the drawings, and the detailed description is omitted. 〃 Figure 4, and the figure! The difference between the configuration of the bonding device 1 is: the collet and the blowing portion 'the bonding device 1', the through hole 22 of the collet 2 is not only used to attract the wafer 8' but also to blow ions to the surface of the wafer 8. Gas. Further, a series of suction lines for sucking the vacuum source 62 and the valve 64 for holding the wafer 8, and a blowing gas source 42 for blowing the ionized gas to the wafer 8, the valve 44, and the static discharger 46 are blown up. Both of them are connected to the switching unit 66 to constitute the suction blowing unit 26. The control unit 8 controls the timing at which the two series of lines of the suction blowing unit 26 are connected to the suction holes. As illustrated in Fig. 2, the through hole 22 is a hole that is opened in the center of the flat surface of the bottom surface of the collet. The through hole 22 is connected to the switching portion 66 of the suction blowing portion 26 . The switching portion 66 has a function of selectively connecting the suction line or the blowing series line to the through hole 22, or both of them to be open, that is, to open to the atmospheric pressure. The selection of the switching unit 66 will be described using FIG. In the discharge operation of the si〇, the through hole 22 is opened to atmospheric pressure. When the positioning step of si is performed, the through hole 22 is also opened to atmospheric pressure. In the blowing step of S14, the through hole 22 is connected to the blowing line. That is, the series of lines of the pressurized gas source 42, the valve 44, and the static eliminator 46 are connected to the through hole 22, as illustrated in FIG. 3, 'the function control valve 44 of the module 86 is blown by the control unit 8〇, 13 1335051, The ionized gas having a stronger gas flow is blown to the surface of the wafer 8 through the through holes 22 of the collet 2G in a short period of time. In the above example, the short period is 0.1 second, and the pressure of the stronger gas flow pressurized gas source 42 is several atm. In the top step of S16 after the blowing step, the through hole 22 is opened to atmospheric pressure. In the pickup step of S18, the through hole 22 is connected to the suction line. That is, the series of lines of the vacuum source 62 and the valve 64 are connected to the through hole 22, and as shown in FIG. 3, the wafer 8 is sucked and held by the through hole 22 of the collet 20 by the function of the pickup processing module 9 of the control unit 80. . In the bonding step of s2〇, when the wafer 8 is transferred and the die bonding is performed, the through hole 22 is connected to the suction series line. After the bonding is completed, the through hole 22 is opened to the atmosphere. As described above, the connection of the through-holes of the collet is switched between the atmospheric pressure, the blowing series line, and the suction line, and the blowing step and the suction step are not repeated. Therefore, when a stronger ionized gas is blown, The top and the attraction will not be ordered, and the wafer will not be blown away by blowing. Further, since the through hole penetrating through the collet is blown from the upper side of the wafer, foreign matter or the like under the collet can be removed more efficiently. According to this, it is possible to further effectively prevent the foreign matter from being located between the flat surface of the flat collet and the surface of the wafer. Further, it is not necessary to provide a special nozzle for blowing.
