Abstract

PURPOSE:To produce a high-precision dish for bonding workpieces, by compensating thermal deformation caused by polishing materials with different coefficients of thermal expansion. CONSTITUTION:Thermal distribution caused by polishing a bonding dish in the direction of thickness is approximately linear, the temperature on a bonding surface A being higher than that on the opposie side. This generates a bending moment to deform the bonding dish 1, so that the bonding surface A becomes convex. Since a disc 6, made of different material and clamped to the side B opposite to the bonding surface A, has a coefficient of thermal expansion larger than that of the bonding plate 1, its elongation is large enough to generate a bending moment for deforming the bonding plate 1, so that the work bonding surface A becomes concave, despite the fact that the temperature on the opposite side B is smaller than that on the bonding surface A. The thickness of the disc 6 made of foreign material is adjusted to balance both moments, which can produce a high-precision bonding dish 1 without thermal deformation.
