491752 A7 ____· Β7___ 五、發明說明(丨) [技術領域] 本發明,係關於一種在製造如ULSI之半導體元件之 方法中,適用於半導體平坦化硏磨等之硏磨裝置。 [習知技術] 近年來,作爲半導體元件等表面之全晶圓平坦化技術 ,係採用化學機械硏磨(化學機械硏磨或化學機械平坦化, 以下稱CMP)技術。CMP,係在物理硏磨中倂用化學作用( 硏磨劑,經由溶液之溶出)來除去晶圓表面凹凸之製程。以 CMP進行硏磨之硏磨裝置,具備硏磨墊等之硏磨體、與固 定晶圓等硏磨對象物之夾頭等的保持部,在硏磨體與前述 硏磨對象物間介入於硏磨劑之狀態下,對硏磨體與硏磨對 象物施加負荷,且藉由相對移動,來硏磨硏磨對象物。 此種硏磨裝置,對硏磨對象物進行硏磨時,因硏磨體 與硏磨對象物之相對移動,而有硏磨體之一部份暫時自硏 磨對象物之周圍突出。習知技藝中,提供了一種例如將面 朝上而被真空吸附於夾頭之晶圓,以安裝在具角度追隨性 之彈性硏磨頭部之小硏磨墊(較晶圓直徑小之硏磨墊)加以 硏磨時,硏磨墊從晶圓暫時突出的硏磨裝置。 [發明欲解決課題] 晶圓等之硏磨對象在硏磨時,前述習知之使硏磨墊等 之硏磨體從硏磨對象物之周圍突出的硏磨裝置,因硏磨墊 從晶圓突出時產生之突出,有以下說明的3個問題。 4 ^紙張尺度適用中國國家標準(CNS)A4規格(210 X 297公釐^" " ' ' ' · I I I Γ--ί ^ . I I------ (請先閱讀背面之注意事項再填寫本頁} 491752 A7 ___;_B7 _ 五、發明說明(/ ) (請先閱讀背面之注意事項再填寫本頁) 第1問題係「硏磨墊之傾斜」。習知之硏磨裝置,爲 了吸收起因於加工組裝之硏磨墊面與夾頭面之平行度誤差 、及晶圓表面之***等,係採用頭部爲具角度追隨性之彈 性機構。因而,在搖動中當硏磨墊從晶圓突出時,相反地 此彈性會出現在背面而使硏磨墊向突出側傾斜,產生無法 進行期望之硏磨的問題。具體而言,硏磨墊對晶圓施加之 壓力不能形成均等分布,其結果產生晶圓端部被削去最多 之(edge first)現象,硏磨難以均一進行。 第2問題係「硏磨墊之高低差」。硏磨墊未從晶圓突 出之部位雖被加壓力壓潰,但突出之部位由於硏磨墊材料 之復原力而變得較未突出之部分爲厚。加壓力釋放後回復 此厚度之區域,因頭部之旋轉而再度接觸晶圓。此高低差 部跨上晶圓之瞬間,由於加壓力釋放後之硏磨墊面再被急 遽壓縮,因此晶圓所承受之加壓狀態在邊緣附近是不均一 的。被壓潰之硏磨墊在自加壓力釋放之瞬間亦會發生同樣 現象。由於此一原因,在晶圓之邊緣附近無法得到所期望 之硏磨。 第3問題係「硏磨墊之加壓力」。硏磨墊對晶圓之加 壓力,對硏磨狀態具有非常大的影響力。基本上’爲了對 晶圓全體進行均一之硏磨,硏磨墊對晶圓之每單位面積的 加壓力最好是均等。但是,如上所述,習知硏磨墊從晶圓 突出時導致接觸面積變化,結果每單位面積之施加壓力變 化。 爲解決此等問題,可考慮設置一導件,以在晶圓硏磨 5__ 本紙張尺度適用中國國家標準(CNS)A4規格(210 X 297公釐) 491752 A7 _____R7___ 五、發明說明(> ) 時支持從晶圓周圍突出之硏磨墊的突出部分。此時,若將 導件支持前述突出部分之引導面,配置在與晶圓之硏磨面 大致相同之面內的話,即使硏磨墊從晶圓突出,亦與硏磨 墊未從晶圓突出之狀態實質上同等之狀態,前述第1至第 3問題可獲得解決而能均一進行硏磨對象物之硏磨。 但是,由於硏磨墊突出部分與導件互相摩擦,因此前 述部分之硏磨墊有加速磨損之危險,且導件亦有磨損之危 險。不過,引導面之高度與晶圓之硏磨面之高度差愈小, 愈能充分發揮支持硏磨構件突出部分之導件的效果,而能 充分解決上述第1至第3問題。因此,基板上,導件係使 用較晶圓耐磨損性更佳之材料。因而,硏磨墊之磨損進一 步加速進行時,硏磨墊之壽命變短。又,即使導件使用耐 磨損性優良之材料,導件之磨損進行愈慢愈好。 又,由於如前述般引導面之高度與晶圓之硏磨面之高 度差愈小愈好,所以在導件之設置時,以兩者之高度一致 設定導件之高度。但,持續使用時,導件逐漸磨損’兩者 高度差變大。因而,有必要再度調整導件高度使兩者之高 度一致。當然,亦可交換導件而不進行高度之再調整,但 將造成成本的增加。是以,相應於導件磨損之進行有調整 導件高度之必要,且此一調整要求能容易的進行。 此外,前述硏磨裝置,在持續使用時,會因硏磨墊堵 塞而無法得到充分之硏磨特性。因而,係以一適當頻率’ 使用修整器等進行調整。但是,習知者卻無法在晶圓之硏 磨中進行調整,使得晶圓硏磨之效率降低。 6 本紙張尺度適用中國國家標準(CNS)A4規格(210 X 297公釐) *裝----*---.— 訂--------- (請先閱讀背面之注意事項再填寫本頁) 491752 A7 _______B7______ 五、發明說明(々) 本發明,有鑑於上述情事,其目的係提供一種將硏磨 體從硏磨對象物周圍突出所導致之問題,以導件支持前述 突出部分來加以解決,且能降低導件與硏磨體之磨損的硏 磨裝置。 又,本發明之另一目的,係提供一種將硏磨體從硏磨 對象物周圍突出所導致之問題,以導件支持前述突出部分 來加以解決,且能容易進行導件高度調整的硏磨裝置。 本發明之再一目的,係提供一種將硏磨體從硏磨對象 物周圍突出所導致之問題,以導件支持前述突出部分來加 以解決,且在硏磨對象物之硏磨中多少可得硏磨體之調整 效果與提升硏磨對象物之硏磨效率的硏磨裝置。 本發明人之硏究結果,發現例如將晶圓等以具角度追 隨性之彈性支持機構的夾頭加以保持,使晶圓等從硏磨墊 等之硏磨體周圍突出之硏磨裝置,亦會產生與前述第1問 題同樣之問題。 : 因而,本發明之目的,係針對此種型式之硏磨裝置, 亦能提供一種能解決與前述第1問題相同問題的硏磨裝置 [解決課題之手段] 爲解決上述課題,本發明之第1態樣之硏磨裝置,具 備硏磨體、·與保持硏磨對象物之保持部,在將硏磨劑介入 於前述硏磨體與前述硏磨對象物之狀態下,藉於前述硏磨 體與前述硏磨對象物之間施加負荷,且使其等相對移動, _ 7 本紙張尺€^中國國家標—準(CNS)A4規格(21〇 x 297公爱) ~ — -------------I

被支持爲能在與前述硏磨對象物之硏磨面大致平行之面內 的既定方向,與前述保持部獨1的運動自如。 根據此第1態樣,由於具備導件’所以可解決硏磨體 從硏磨對象物周圍突出所伴隨之前述第1至第3問題。此 外,前述第1態樣中,導件係被支持爲與保持部呈獨立的 運動自如,因此與後述之第3態樣般,藉由與硏磨體突出 部分之摩擦力使導件隨著突出部分移動,或如後述之第4 態樣般,藉由致動器驅動導件’以一體固定導件與保持部 之情形等相較,可降低硏磨體之突出部分與導件中與前述 突出部分相對部分的相對速度。因此,根據前述第1態樣 ,能降低硏磨墊等之硏磨體與導件之磨損。 本發明第2態樣之硏磨裝置,係前述第1態樣中之前 述導件,被支持爲與前述保持部呈獨立地、繞與前述保持 部之旋轉軸大致相同軸旋轉自如。以此第2態樣之方式支 持導件,即能使機構變得簡單而降低成本。惟,前述第1 態樣並非僅限於此例。 本發明第3態樣之硏磨裝置,係前述第丨或第2態樣 中之則述導件,藉由從則述突出部分接受之摩擦力而隨著 前述突出部分移動。 根據此第3態樣,由於僅需以所謂自邮方式支持 8 本紙張尺度適i中國國家標準(CNS)A4;m格(210 X 297公0 ---—-- ------------^^裝----.----丨tr··--------- (請先閱讀背面之注意事項再填寫本頁) 491752 A7

對部分的相對速度降低,或如後述第8態樣般,導件具有 修整區域之情形時,使前述突出部分與前述修整區域間之 相對速度成爲適合前述硏磨體之調整的速度。 本發明第5態樣之硏磨裝置,係於前述第4態樣中具 備用以控制前述致動器之控制部,以使前述突出部分與前 述導件中與前述突出部分面對之部分間的相對速度降低。 根據第5態樣,由於前述突出部分與前述導件中與前 述突出部分面對之部分間的相對速度會降低,因此能減少 硏磨體與導件之磨損。前述第3態樣,由於導件係藉由突 出部分接受之摩擦力而隨之移動,因此無法避免突出部分 與引導部分間之相對速度產生滑動成分之速度。對此,前 述第5態樣,由於能藉由致動器使導件主動進行運動,因 此能消除此滑動成分,使突出部分與導件間之相對速度更 爲降低。因此,可使硏磨體與導件之磨損更加減少。 本發明第6態樣之硏磨裝置,係前述第1或第2態樣 中,具備使前述導件振動之勵振部,以藉由振動在前述引 導面形成凹凸。 9 木紙張尺度適用中國國家標準(CNS)A4規格(210 X 297公釐) ------------------'1 ^--------- (請先閱讀背面之注意事項再填寫本頁) 491752 A7 ____B7_________ 五、發明說明(Ί ) 前述振動,雖以超音波振動或其它之高頻振動較佳, 但並不僅限於此。前述勵振部,例如可在前述引導面產生 駐波、亦可產生行波。前述勵振部,例如可使用壓電元件 、電應變元件或磁應變元件等各種電氣機械能量轉換元件 來構成。上述各點,於後述第9態樣中亦同。 根據第6態樣,由於藉由振動在導件之引導面形成凹 凸,因此引導面相對硏磨體之接觸面積變小,兩者間看起 來摩擦係數變小。因此能更進一步的降低硏磨體與導件之 磨損。又,藉由前述振動,能獲得消除硏磨體堵塞之調整 效果。因而,在硏磨對象物未在硏磨中時不需進行硏磨體 的調整,或降低硏磨以外時之調整的次數,提升硏磨對象 物之硏磨效率。 本發明第7態樣之硏磨裝置,係前述第1或第2態樣 中’對應施加之電氣信號而產生體積變化之元件,係設置 成視該元件之體積變化,而變化以前述硏磨對象物之硏磨 面爲基準之前述引導面的相對高度。 作爲前述元件,例如,可使用壓電元件、電應變元件 或磁應變元件等。此點,於後述之第10與第U態樣中亦 同。 根據第7態樣,由於能藉由變更對前述元件施加之電 氣信號,來調整導件引導面之高度,故該調整變得容易。 本發明第8態樣之硏磨裝置,係前述第1或第2態樣 中’前述引導面之至少一部份爲能進行前述硏磨體之調整 的修整區域。 10 本紙張尺度過用中國國家標準(CNS)A4規格(210 X 297公釐) ·裝----*---丨訂---------

Description of the Invention (丨) [Technical Field] The present invention relates to a honing device suitable for semiconductor planarization honing in a method for manufacturing a semiconductor element such as ULSI. [Known Technology] In recent years, as a full-wafer planarization technology for the surfaces of semiconductor devices, chemical mechanical honing (chemical mechanical honing or chemical mechanical planarization, hereinafter referred to as CMP) technology has been used. CMP is a process of removing unevenness on the wafer surface by chemical action (honing agent, dissolution through solution) in physical honing. A honing apparatus for honing by CMP, including a honing body such as a honing pad, and a holding part such as a chuck for fixing a honing object such as a wafer, and interposing between the honing body and the honing object. In the state of the honing agent, a load is applied to the honing body and the honing object, and the honing object is honed by the relative movement. With this type of honing device, when the honing object is honing, a part of the honing body temporarily protrudes from the periphery of the honing object due to the relative movement of the honing body and the honing object. In the conventional art, a small honing pad (for example, a wafer having a smaller diameter than a wafer diameter) is provided, for example, a wafer which is vacuum-adhered to a chuck and faces upward, and is mounted on an elastic honing head with angular followability. (Hopping pad) A honing device in which the honing pad temporarily protrudes from the wafer when honing. [Problems to be Solved by the Invention] When a honing object such as a wafer is honing, the conventional honing device that causes a honing body such as a honing pad to protrude from the periphery of the honing object, because the honing pad is lifted from the wafer There are three problems described below when highlighting. 4 ^ Paper size applies to China National Standard (CNS) A4 specifications (210 X 297 mm ^ " " '' 'III Γ--ί ^. I Please read the note on the back first Please fill in this page again for matters} 491752 A7 ___; _B7 _ 5. Description of the invention (/) (Please read the notes on the back before filling out this page) The first question is "Tilt of the honing pad". Known honing device, In order to absorb the parallelism error between the honing pad surface and the chuck surface caused by processing and assembling, and the ridge of the wafer surface, the elastic mechanism with the head following the angle is adopted. Therefore, when the honing pad is shaken, When protruding from the wafer, this elasticity will, on the contrary, appear on the back side and cause the honing pad to tilt toward the protruding side, resulting in the problem that the desired honing cannot be performed. Specifically, the pressure applied to the wafer by the honing pad cannot be equalized. Distribution, as a result, the edge of the wafer is chipped at the edge (edge first) phenomenon, the honing is difficult to uniformly. The second problem is the "height of the honing pad". Although the honing pad does not protrude from the wafer, It was crushed by pressure, but the protruding part was restored by the honing pad material. The part that becomes less prominent due to the force is thicker. After the pressure is released, the area returned to this thickness will contact the wafer again due to the rotation of the head. The moment the level difference crosses the wafer, the pressure is released after the pressure is released. The surface of the honing pad is compressed again, so the pressure state of the wafer is not uniform near the edge. The same phenomenon occurs when the crushed honing pad is released from the pressure. For this reason The desired honing can not be obtained near the edge of the wafer. The third problem is the "pressure of the honing pad". The pressure of the honing pad on the wafer has a great influence on the honing state. Basic In order to uniformly hob the entire wafer, it is preferable that the honing pad applies a uniform pressure to the wafer per unit area. However, as described above, the conventional honing pad causes a contact area when protruding from the wafer. Change, resulting in a change in the applied pressure per unit area. In order to solve these problems, a guide can be considered to hob the wafer 5__ This paper size applies the Chinese National Standard (CNS) A4 specification (210 X 297 mm) 491752 A7 _____R7___ 5. In the description of the invention (>), the protruding portion of the honing pad protruding from the wafer is supported. At this time, if the guide supports the guiding surface of the protruding portion, it is arranged substantially the same as the honing surface of the wafer. If the honing pad is protruding from the wafer, the state is substantially the same as the state where the honing pad is not protruding from the wafer. The first to third problems can be solved and the honing object can be uniformly performed. However, since the protruding portion of the honing pad and the guide member rub against each other, the honing pad of the aforementioned section may be subject to accelerated wear, and the guide member may also be subject to wear. However, the height of the guide surface is the same as that of the wafer. The smaller the height difference of the honing surface, the more fully the effect of the guide supporting the protruding portion of the honing member can be fully exerted, and the above-mentioned first to third problems can be fully solved. Therefore, on the substrate, the guide is made of a material with better wear resistance than the wafer. Therefore, when the wear of the honing pad is further accelerated, the life of the honing pad becomes shorter. In addition, even if the guide is made of a material having excellent wear resistance, the slower the wear of the guide is, the better. In addition, as described above, the smaller the difference between the height of the guide surface and the height of the honing surface of the wafer is, the better, so when the guide is set, the height of the guide is set in accordance with the height of the two. However, when continuously used, the guide member gradually wears out 'and the difference in height between the two becomes larger. Therefore, it is necessary to adjust the height of the guide again so that the heights of the two are consistent. Of course, it is also possible to exchange the guides without readjusting the height, but this will increase the cost. Therefore, it is necessary to adjust the height of the guide according to the wear of the guide, and this adjustment can be easily performed. In addition, the honing device described above cannot obtain sufficient honing characteristics due to blockage of the honing pad during continuous use. Therefore, adjustment is performed using a trimmer or the like at an appropriate frequency. However, the knowledgeable person cannot adjust the wafer honing, which reduces the efficiency of wafer honing. 6 This paper size is applicable to China National Standard (CNS) A4 specification (210 X 297 mm) * Packing ---- * ---.— Order --------- (Please read the notes on the back first (Fill in this page again) 491752 A7 _______B7______ 5.

The honing member 1 is used to fix the honing body (honing pad) 7 below the honing platform 6 by an unillustrated mechanism, as shown by arrows J, K, and M in Figs. 1 and 3. , Can rotate, move up and down and shake left and right (back and forth). As the honing body 7, for example, a sheet-like foamed polyurethane or a non-foamed resin having a groove structure on the surface can be used. The holding part 3 is formed with a chuck 8 (having a large number of air passages (not shown) and capable of vacuum-adhering the wafer 2 to it), a chuck table 9 (for supporting the chuck 8), and a member 10 constituting a rotating shaft. Well-known structure for one body. The holding portion 3 is provided with a pipe 11 for vacuum suction and the like. The wafer 2 is supported on the holding portion 3 by vacuum suction, and the upper surface of the wafer 2 is a honing surface. The holding portion 3 can be rotated by an unillustrated mechanism using an electric motor as a driver, as indicated by an arrow N in FIG. 1. The diameter of the honing member 1 is smaller than the diameter of the wafer 2. When honing the wafer 2, due to the swing in the direction indicated by the arrow M of the honing member 1, as shown in Figs. 1 and 3, a part of the honing body 7 temporarily protrudes from the wafer 2 toward the periphery. 5. It is supported to move independently from the holding portion 3 in a predetermined direction in a plane substantially parallel to the honing surface of the wafer 2. Specifically, in this embodiment, the guide 5 is made of a ceramic material, such as zirconia or alumina, which has excellent wear resistance, and is formed in a ring shape. ) A4 specification (21〇X 297 mm) ---------------.— ί ^ --------- (Please read the notes on the back before filling in this (Page) 491752 A7 _________ 5. Description of the Invention (lk) The shaft is arranged along the outer periphery of the holding portion 3. The upper surface of the guide 5 is a guide surface 5a that supports the protruding portion of the honing body 7 during honing. The guide 5 is mounted on the member 13 through an annular bearing 12 provided coaxially with the holding portion. The guide 5 is supported to pass through the bearing 12 through the member 13 and is coaxial with the holding portion 3 but independently rotates from the holding portion 3 freely. . The aforementioned member 13 is a member that supports the holding portion 3 as a member that can rotate freely in the direction of the arrow N or a member that is fixed thereto. For example, when the indexing table structure disclosed in JP-A-2000-127028 is adopted, the component 13 is an indexing table or a member fixed thereto. The indexing table supports a plurality of holding portions 3 as rotatable ones. If an indexing table is used, when one of the holding sections 3 is located at the honing table, the other holding sections 3 may be located at the loading position and the unloading position, etc., and can hob a plurality of wafers 2 with good efficiency. Nevertheless, the honing apparatus of the present invention may have only a single holding portion 3. In this embodiment, in order to prevent the honing agent from rotating into the bearing 12, as shown in FIG. 2, the gap between the guide 5 and the member 13 adopts a labyrinth structure. However, a sealing member made of resin or the like may be used to prevent the honing agent from rotating into the bearing 12, for example. Alternatively, the guide 5 may be attached to the member 13 through the bearing 12, instead of attaching the guide 5 to the holding portion 3 through the bearing 12. At this time, although the guide 5 is supported by the holding portion 3, it is rotatable independently from the holding portion 3. According to the honing apparatus of this embodiment, the honing member 1 swings in the direction of the arrow M while rotating in the direction of the arrow J, and is crimped onto the wafer 2 on the holding portion 3 with a predetermined pressure. If the holding part 3 is rotated in the direction of the arrow N, the wafer 19 paper size is applicable to the Chinese National Standard (CNS) A4 specification (21G X 297g). »Installation —.— ^ Order --------- (please first Read the notes on the back and fill in this page) 491752 A7 ____B7 __ Jade and invention description (\ Ί) (Please read the notes on the back before filling in this page) 2 also rotate in the direction of arrow N, so that the wafer 2 and 硏The grinding member 1 performs a relative movement. In general, in order to increase the honing rate, as shown in FIG. 3, the rotation direction of the wafer 2 (the arrow N direction) is opposite to the rotation direction of the honing body 7 (the arrow J direction) to increase the relative speed. . In this state, the honing agent is supplied from the honing agent supply unit 4 to the wafer 2, and the honing is spread on the wafer 2 and enters the honing body 7 with the relative movement of the honing member 1 and the wafer 2. To the honing surface of the wafer 2 with the wafer 2. That is, the mechanical honing of the relative movement of the honing member 1 and the wafer 2 and the chemical action of the honing agent interact to perform good honing. At this time, as shown in FIG. 1, as the honing member 1 swings in the M direction in FIG. 1, a part of the honing body 7 temporarily protrudes from the wafer toward its periphery. However, since this protruding portion is substantially on the same surface as the honing surface of the wafer 2 and is supported by the guide 5 near the outer periphery of the wafer 2, the honing body 7 and the state not protruding from the wafer 2 are substantially related. Equivalent status. As a result, the aforementioned first to third problems are eliminated, and the wafer 2 can be honed uniformly. In this embodiment, since the guide 5 is supported coaxially with the holding portion 3, but with the holding portion 3 3 is independently rotatable. Therefore, as shown in FIG. 3, the guide 5 receives the frictional force from the protruding portion of the honing body 7, and moves with the protruding portion of the honing body 7 and rotates in the direction of arrow P. Therefore, the peripheral speed of the protruding portion of the 'honing body 7' and the peripheral speed of the guide member 5 facing the aforementioned protruding portion become approximately the same speed. When the sliding speed is subtracted from the relative speed of the two, it approaches zero. Therefore, according to this embodiment, the wear of the honing body 7 and the guide 5 can be significantly reduced. In addition, because the peripheral speed of the guide 5 and the 20 paper standards are applicable to the Chinese National Standard (CNS) A4 specification (210 X 297 mm) 491752 A7 ________B7____ 5. Description of the invention (丨 Male) The peripheral speed of the honing body 7 is approximately equal Therefore, the particles of the wafer 2 generated by the honing agent or the honing can be smoothly discharged without being subjected to an external force, and these particles cannot easily penetrate into the fiber of the honing body 7 and cause the blockage of the honing body 7. Next, a comparative example compared with this embodiment will be described with reference to Fig. 4. FIG. 4 is a schematic plan view corresponding to FIG. 3, and in FIG. 4, the same or corresponding elements as those in FIG. 3 are given the same symbols, and repeated explanations are omitted. This comparative example differs from this embodiment in that the guide 5 is integrally fixed to the holding portion 3 and rotates in the direction of arrow P 'which is the same as the direction of rotation (arrow N direction) of the wafer 2. Therefore, in this comparative example, the relative speed of the protruding portion of the honing body 7 and the facing portion of the guide member 5 facing the aforementioned protruding portion becomes significantly larger, and the wear of the protruding portion of the honing body 7 and the guide member 5 becomes larger. Also, because the relative speed of the guide 5 and the honing body 7 is large, the particles of the wafer 2 generated by the honing agent or honing are discharged by unnecessary external force, so it is easy to sneak into the fibers of the honing body 7 Inside, it is easy to cause the honing body 7 to block. That is, even when the guide member 5 is fixed to the member 13 as a whole, the aforementioned relative speed becomes quite large, and the wear of the honing body 7 and the guide member 5 will eventually increase, which will easily cause the honing body to be blocked. «Second Embodiment» Fig. 5 is a schematic enlarged sectional view of a main part of a honing apparatus according to a second embodiment of the present invention, and corresponds to the aforementioned second figure. Fig. 7 'is a schematic plan view showing the honing apparatus of the present embodiment, and corresponds to Fig. 3 described above.

49之間,因此在各電極43A,43B與電極42間分別 施加直流電壓Vx時,體積會隨該電壓Vx變化,引導面 5a之高度即成爲對應電壓Vx之高度。 承上所述,若將第13(a)、(b)圖所示之電壓Va,Vb(分 別相當於在第11(a)、(b)圖所示之交流電壓加上直流電壓 Vx之電壓),分別施加於各電極43A與電極42之間、及各 電極43B與電極42之間,而能以可變電阻器等來調整直

Description of the invention (to) Open And an example of a driving circuit for driving the piezoelectric element 40. In this embodiment, the driving circuit 50 is composed of an AC power source 51 and a phase changer 52 (the output voltage is changed by 180 degrees). In addition, the driving circuit 50 is electrically connected to the electrodes 42, 43A, 43B through the slip rings 44 to 46 (not shown in FIG. 10) as shown in FIG. The AC voltage Va shown in U (a) is shown, and the AC voltage Vb shown in FIG. 11 (b) is applied between each of the electrodes 43B and 42. The frequency of the alternating voltage Va, Vb is equal to the frequency of the eighth bending mode, and the eighth bending mode of the ring-shaped member composed of the guide 5 and the piezoelectric element 40 is excited. By the application of this voltage Va, Vb, the standing wave shown by the imaginary curve and the one-point chain curve in Fig. 10 is generated on the guide surface 5a of the guide member 5. Fig. 12 (a) shows the expansion and contraction of the piezoelectric body 41 and the unevenness of the guide surface 5a of the guide 5 corresponding to the time point of the dashed curve in Fig. 10. Fig. 12 (b) shows the expansion and contraction of the piezoelectric body 41 and the unevenness of the guide surface 5a of the guide 5 corresponding to the point of the chain curve of one point in Fig. 10. As described above, since the guide surface 5a of the guide member 5 has irregularities due to standing waves, the contact area between the guide surface 5a and the honing body 7 becomes smaller ', and the coefficient of friction between the two is significantly reduced. Therefore, according to this embodiment ', the wear of the honing body 7 and the guide 5 can be further reduced. In addition, the adjustment effect of eliminating the blockage of the honing body 7 can also be obtained by the minute ultrasonic vibration. For the purpose of obtaining this effect, the piezoelectric element 40 may be used to excite the guide 5. In this case, it is not necessary to perform the excitation at any time during the honing of the wafer 2 ', and the vibration can be performed only when the adjustment effect is desired. In addition, instead of standing waves generated on the guide surface 5a, for example, 27 papers are produced.

Description of the invention (〆) The same effect can be obtained when traveling waves . To generate a progressive wave, 90 ° can be used. A phase changer replaces the 180 ° phase changer 52. In this embodiment, although the guide member 5 is supported coaxially with the holding portion 3 by bearings 12, 49, but independently rotates freely from the holding portion 3, the bearings 12, 49 are removed, for example, the mounting member 47 , 48 may be fixed to the member 13. Even in this case, since the contact area of the guide surface 5a with the honing body 7 is reduced due to the standing wave, in addition to the effect of reducing the wear of the honing body 7 and the guide 5, the aforementioned adjustment effect can be obtained. Furthermore, since the piezoelectric element 40 is disposed between the guide 5 and the bearings 12, 49 as described above, when a DC voltage Vx is applied between each of the electrodes 43A, 43B and the electrode 42, the volume will follow the voltage Vx. The height of the guide surface 5a becomes the height corresponding to the voltage Vx. As mentioned above, if the voltages Va and Vb shown in Figs. 13 (a) and (b) (respectively correspond to the AC voltage shown in Figs. 11 (a) and (b) plus the DC voltage Vx) Voltage), which is applied between each electrode 43A and electrode 42 and between each electrode 43B and electrode 42 and the magnitude of the DC voltage Vx can be adjusted by a variable resistor or the like (this circuit configuration itself is known) That is, the height of the guide portion 5a of the guide 5 can be adjusted very easily. Therefore, even when the guide 5 needs to be readjusted in the height direction due to wear due to long-term use, its adjustment is extremely simple. In the case where the piezoelectric element 40 is used only for the purpose of performing such height adjustment, between the electrodes 43A and 42 and between the electrodes 43B and 42 as long as the 14th (a), (B) The AC components shown in the figure and the DC voltages Va and Vb that can adjust the level are sufficient.
