PROTECTIVE FILM FOR SEMICONDUCTORS, SEMICONDUCTOR DEVICE AND COMPOSITE SHEET

摘要

Provided are: a protective film for semiconductors, which is capable of suppressing warp of a semiconductor chip without deteriorating the productivity and reliability; a semiconductor device which is provided with this protective film for semiconductors; and a composite sheet. A protective film 10 for semiconductors according to one embodiment of the present invention is provided with: a protective layer 11 that is configured from a non-conductive inorganic material; and an adhesive layer 12 that is provided on one surface of the protective layer 11. The protective layer 11 contains at least a vitreous material, and is typically configured of a glass sheet. Consequently, warp of a semiconductor element, which is an object to be protected, is able to be effectively suppressed.
