Abstract

The present invention provides an encapsulant with a base for use in semiconductor encapsulation, for collectively encapsulating a device mounting surface of a substrate on which semiconductor devices are mounted, or a device forming surface of a wafer on which semiconductor devices are formed, the encapsulant comprising the base, an encapsulating resin layer composed of an uncured or semi-cured thermosetting resin formed on one surface of the base, and a surface resin layer formed on the other surface of the base. The encapsulant enables a semiconductor apparatus having a good appearance and laser marking property to be manufactured.
