Claim Text:
1. A method for manufacturing a semiconductor apparatus, comprising: a covering step of covering, with an uncured resin layer of a first fiber-containing resin substrate, at least one semiconductor device mounting surface of a second substrate having the at least one semiconductor device mounted thereon or at least one semiconductor device forming surface of a wafer having the at least one semiconductor device formed thereon; a sealing step of collectively sealing the at least one semiconductor device mounting surface of the second substrate having the at least one semiconductor device mounted thereon or the at least one semiconductor device forming surface of the wafer having at least one semiconductor device formed thereon by heating and curing the uncured resin layer to provide a sealed substrate having the at least one semiconductor device mounted thereon or a sealed wafer having the at least one semiconductor device formed thereon; and a piece forming step of dicing the sealed substrate having the at least one semiconductor device mounted thereon or the sealed wafer having the at least one semiconductor device formed thereon into each piece to manufacture the semiconductor apparatus, wherein the first fiber-containing resin substrate comprises a two-layered structure consisting of a resin-impregnated fiber base material obtained by impregnating a fiber base material with a thermosetting resin and semi-curing or curing the thermosetting resin, and the uncured resin layer containing an uncured thermosetting resin and formed on one side of the resin-impregnated fiber base material, and wherein a thickness of the uncured resin layer is not smaller than 20 microns and not greater than 200 microns.
