20210384183 · 2021-12-09 · ·

Provided is a technique suitable for multilayering thin semiconductor elements via adhesive bonding while avoiding wafer damage in a method of manufacturing a semiconductor device, the method in which semiconductor elements are multilayered through laminating wafers in which the semiconductor elements are fabricated. The method of the present invention includes bonding and removing. In the bonding step, a back surface 1b side of a thinned wafer 1T in a reinforced wafer 1R having a laminated structure including a supporting substrate S, a temporary adhesive layer 2, and the thinned wafer 1T is bonded via an adhesive to an element forming surface 3a of a wafer 3. A temporary adhesive for forming the temporary adhesive layer 2 contains a polyvalent vinyl ether compound, a compound having two or more hydroxy groups or carboxy groups and thus capable of forming a polymer with the polyvalent vinyl ether compound, and a thermoplastic resin. The adhesive contains a polymerizable group-containing polyorganosilsesquioxane. In the removing step, a temporary adhesion by the temporary adhesive layer 2 between the supporting substrate S and the thinned wafer 1T is released to remove the supporting substrate S.

INTERLAYER FILLER MATERIAL FOR TOUCH PANELS, AND LAMINATE

An interlayer filling material for a touch panel which is used for filling an interlayer space between a touch panel and another component or an interlayer space between transparent conductive films included in the touch panel in production of a personal digital assistant, which is excellent in followability to steps of a decorative printing portion or wiring upon filling of an interlayer space (lamination) and also excellent in defoaming properties to release air bubbles entrapped during filling of an interlayer space (lamination) or air bubbles left near the steps, which is less likely to be whitened and less likely to deteriorate an ITO film even under a high-temperature and high-humidity environment. The present invention also aims to provide a laminate produced using the interlayer filling material for a touch panel. The interlayer filling material includes: a polyvinyl acetal; a plasticizer; and an organic acid.
