Abstract

PURPOSE:To hold uniformly the gap between a mask and a wafer and also to reduce the arrangement density of the vertically driving elements for deformation and to contrive a reduction in the cost and the lightening by a method wherein the chucking plate is formed in the prescribed form by moving the elastically deformable triangular elements forming the chucking plate in the vertical direction. CONSTITUTION:Slit grooves 5 formed their upper point parts in a U-shaped or V-shaped form are bored into a shucking plate 2 for dividing the chucking plate into a plurality of triangle-shaped elements 6 and the chucking plate is formed in such a way that each element 6 can be elastically deformed with the vicinities of the grooves as folded lines. After a wafer 1 having an uneven thickness is mounted on the surface of the chucking plate 2, vacuous air is supplied in air insertion grooves 7 and the wafer is attracted by suction pressure. The height of the flatness degree of the wafer 1 is measured, the upper end part positions of vertical motion mechanisms 3 are adjusted on the basis of the operated results, and the position deviation in the vertical direction of the wafer 1 is suppressed. Then, vacuous air is supplied in internal chambers 4a and the wafer 1 is positioned in a flattened state at the same time as the back surface of the chucking plate 2 is supported by the upper end parts of the vertical motion mechanisms 3 by suction pressure.

Conventionally, for example in LSI, a resist film is formed on a silicon wafer, and a required pattern formed on a mask is transferred to this resist film.
By repeating processes such as etching and ion implantation according to each turn, the LSI is manufactured to have the required circuit. It is required to form fine patterns with a diameter of 1 μm or less. And, in order to meet such demands, the above-mentioned ! It has been proposed to use, for example, soft X-rays to transfer turns.

For example, several X-ray exposure apparatuses using such soft X-rays have been proposed, as described in Japanese Patent Application Laid-open No. 169242/1982, but when soft X-rays are used, It is known that the attenuation from the source to the Lennost film formed on the weno is large.

For this reason, many improvements have been made, such as increasing the amount of soft X-rays generated at the X-ray source, forming the mask from a material that allows soft X-rays to easily pass through, and making the mask as thin as possible. There is.

As masks become thinner, their mechanical strength decreases, making it impossible to make larger masks. For this reason, a step-and-ret type transfer method has been proposed in which masks for 11 to several LSs are created, patterns are transferred one by one, and the patterns are moved one by one. However, as the mask becomes thinner, it is difficult to flatten the mask itself.

On the other hand, soft X-rays travel straight from the source while spreading radially. Further, the soft X-ray generation source has a size corresponding to the diameter of the electron beam irradiated to the anticathode. For this reason, the arrival position of the soft X-rays from the source through the mask to the Lennost coating on the wafer varies depending on the size of the source, resulting in blurring or a slight deviation from just below the mask/grid. A shifter that illuminates the shifted position is generated.

On the other hand, masks are subject to distortion due to errors in mask manufacturing, temperature rise during exposure, distortion due to changes over time in masks that are folded, and deformation due to the mask's own weight due to chucking when attaching the mask to the exposure equipment. There are many undesirable effects such as distortion and distortion due to the difference in air pressure applied to the upper and lower surfaces of the mask. Further, wafers are also subject to many undesirable effects, such as deformation during wafer fabrication, deformation due to chucking during attachment to an exposure apparatus, and deformation occurring during processes such as etching and ion implantation.

in (Vol 15 AIO1973)
WAFERCLAMPING PEDESTALJ is proposed. That is, a piezo element is placed on a stand with holes for vacuum suction. Then, with the wafer placed on the table and vacuum-adsorbed, the heights of multiple points on the surface of the wafer are detected by a sensor, and based on the results, a required voltage of 0 is applied to the piezo element, and the back surface of the wafer is It is configured to push up and level the surface.

However, in such devices, when the piezo element pushes up the wafer, a gap is formed between the table and the wafer, weakening the vacuum's ability to hold the wafer, and causing the wafer to slip due to the airflow flowing through the gear saw. There are disadvantages such as being easy to use.

Furthermore, unless the piezo elements are uniformly arranged over the entire surface of the wafer, the wafer cannot be deformed horizontally or into a desired shape. Therefore, for example, when piezo elements are arranged at intervals of 10+m over the entire surface of a 4-inch wafer, 105
For a 5-inch wafer, 149 piezo elements are required. Similarly, the same number of drive means for the piezo elements as the number of piezo elements are required. The driving means usually needs to apply a voltage of θ to 650 V to the piezo element, and it is technically difficult to miniaturize the piezo element. Therefore, it is technically difficult to equip an exposure apparatus with a large number of driving means, and there are disadvantages such as not only making the apparatus larger than necessary but also making it expensive.

1 to 5 showing embodiments of the present invention will be described below. FIG. 1 is a cross-sectional side view of a wafer flattening apparatus showing an embodiment of the present invention, and FIG. 2 is an enlarged cross-sectional side view of the slit groove connection part. (b) shows the case where the slit groove connection part is formed in a V shape, FIG. 3 is a back view of the chuck plate, and FIG. 4 is an explanatory diagram of the operation of flattening the wafer.
(,) shows the state in which the wafer is vacuum-adsorbed onto the chuck plate, and (b) shows the state in which the wafer is flattened. In the figure, 1 is a wafer, 2 is a chuck plate, which is formed into a flat plate shape, and on the back side, as shown in FIG. ,
The upper tip part is formed into a mouth shape as shown in FIG. 2(a) or a mouth shape as shown in FIG. 6 is formed to be elastically deformable. Further, the chuck plate 2 has an air insertion groove 7 formed on its surface at a position opposite to the slit groove 50 for vacuum suction of the wafer l onto the chuck plate 2, and a position connected to the air insertion groove 7 of the bracket. Air passage holes 8 are bored so as to penetrate in the vertical direction. Reference numeral 4 is a hose song, which is formed into a cylindrical shape with a mouth-shaped cross section, and has an internal chamber 4a that is sealed when the back side of the chuck plate 2 is supported on its upper end surface. A plurality of up and down mechanisms 3 are housed in the chamber 4a so as to be located at position A near the back corner of each element 6 of the chuck plate 2. Although the specific structure of the vertical mechanism 3 is omitted, in the case of the present invention, a drive stroke of about 20 to 30 μm and a resolution of about 0.1 μm are required, so a piezo element or the like is used, for example. However, since this piezo element is commonly used, detailed explanation will be omitted. Reference numerals 9 and 10 designate vacuum supply holes, which are bored horizontally through the inner and outer peripheral surfaces of the housing 4, and whose outer peripheral openings are connected to a vacuum supply source (not shown). Inner opening of hole 9.
The inner circumferential opening of the other vacuum supply hole 10 is connected to the air passage hole 8 through the vacuum tube 11 and the inner chamber 4 of the housing song 4.
Connected to a. Reference numeral 12 denotes a wafer flatness height measuring device, which is formed by a Radhe interference fringe device or a capacitance sensor, and is placed so as to face above the wafer 1. The height of flatness of the surface of the wafer 1 when it is sucked is measured. Reference numeral 13 denotes an arithmetic circuit, which calculates the results of measurement by the wafer flatness height measuring device 12. 14
is a drive circuit, and based on the calculation results of the calculation circuit 13, the predetermined vertical mechanism 3 is driven to adjust the position of its upper end. Since the configuration is as described above, its operation will be described with reference to FIG. First, Figure 4 (&)
As shown in the figure, after a wafer 1 with a non-uniform thickness is mounted on the surface of a chuck plate 2, vacuum air from a vacuum supply source is passed through one vacuum supply hole 9, via 'll and air passage hole 8. When the wafer 1 is supplied into the insertion groove 7 , the wafer 1 is attracted to the surface of the chuck plate 2 by the suction pressure of the vacuum air in the air insertion groove 7 . In this state, the flatness height of the wafer 1 is measured by the flatness height measuring device 12 of the upper wafer 1, and the result is calculated by the calculation circuit 13. Based on the calculation result, the drive circuit 14 is driven to adjust the upper end position of the predetermined vertical mechanism 3, thereby suppressing vertical positional deviation of the wafer 1. Next, as shown in FIG. 4(b), when vacuum air from the vacuum supply source is supplied to the internal chamber 4a of the 7-unong 4 through the other vacuum supply hole 10, the suction pressure of the vacuum air in the internal chamber 4a causes The chuck plate 2 and the wafer 1 are deformed downward so that the back surface of the chuck plate 2 is supported by the upper end of the vertical mechanism 3, and the wafer 1 is positioned in a flattened state via the chuck plate 2. Although the above embodiment is described with respect to an apparatus for flattening a wafer 1, the present invention is not limited thereto. For example, the present invention is not limited to this. Needless to say, this method is also applied when shaping a curved surface.

As described above, when the present invention is applied to flatten a wafer, the wafer surface can be flattened to within ±0.5 μm, and unevenness in the thickness of the wafer can be removed. It is possible to perform pattern transfer with submicron precision using an exposure device, and this is particularly advantageous when it is necessary to hold the mask uniformly in the gap between the mask and the wafer, such as in an X-ray exposure device. In addition, when shaping the weno 1 into a curved surface, the weno is deformed as a polygonal line near the slit groove of the chuck plate, so the arrangement density of the up and down mechanisms for deformation can be reduced to about 2 compared to conventional methods. This has the effect of reducing the cost and weight of the device.
