SPACER FORMATION FILM, SEMICONDUCTOR WAFER AND SEMICONDUCTOR DEVICE

摘要

A spacer formation film is adapted to be used for forming a spacer defining air-gap portions on a side of one surface of a semiconductor wafer and by being cut into a desired shape, the spacer formation film includes: a support base having a sheet-like shape; a spacer formation layer provided on the support base and having a bonding property, the spacer formation layer formed of a material containing an alkali soluble resin, a thermosetting resin and a photo polymerization initiator; and a cutting line along which the spacer formation film is to be cut, wherein the spacer formation layer is provided inside the cutting line so that a peripheral edge thereof is not overlapped to the cutting line.
