FILM FOR TEMPORARY FIXING, FILM SHEET FOR TEMPORARY FIXING AND SEMICONDUCTOR DEVICE |
摘要 |
The film for temporary fixing of the present invention is a film for temporary fixing which is used in a processing method of a semiconductor wafer, the method including a temporary fixing step of temporarily fixing the semiconductor wafer to a support via the film for temporary fixing, a processing step of processing the semiconductor wafer that is temporarily fixed to the support, and a separation step of separating the processed semiconductor wafer from the support and the film for temporary fixing, contains (A) a high molecular weight component and (B) a silicone-modified resin, and has a modulus of elasticity of from 0.1 to 1000 MPa at 23° C. after being heated for 30 minutes at 110° C. and for 1 hour at 170° C. |
