AI Technical Summary

Technical Problem

Existing holding members, such as electrostatic chucks, exhibit significant temperature dependency in adhesive strength, limiting their use at high temperatures.

Method used

A holding member comprising a first member, a second member, and an adhesive member with a silicone resin containing aromatic hydrocarbon groups and a hydrophilic filler like alumina, which reduces temperature dependency by minimizing pseudo-crosslinking points through increased SP value difference and sterically hindering micro-crystallization.

Benefits of technology

The adhesive member maintains strength with minimal temperature dependence, allowing the holding member to be used effectively at high temperatures without significant property changes.

Abstract

To provide a holding member in which the strength of an adhesive member has little temperature dependency.SOLUTION: A holding member including a first member, a second member, and an adhesive member that bonds the first member and the second member, wherein the temperature when the first member and the second member are pulled along a shear direction that shears the adhesive member is defined as a tensile temperature (°C), and the stress generated in the adhesive member when the first member and the second member are pulled along the shear direction is defined as a tensile stress (MPa). The value of the tensile stress (MPa) changes within a range of -0.006 MPa or more and less than 0 MPa for every degree increase in the tensile temperature (°C).SELECTED DRAWING: Figure 1
