    摘要: A miniature semiconductor apparatus is outstanding in reflow resistance, temperature cycle property, and PCT resistance corresponding to high density packing, high densification, and speeding up of processing. The semiconductor apparatus has at least one stress cushioning layer on a semiconductor element with an electrode pad formed, having a conductor on the stress cushioning layer, having a conductor for conducting the electrode pad and conductor via a through hole passing through the stress cushioning layer between the electrode pad and the conductor, having an external electrode on the conductor, and having a stress cushioning layer in an area other than the area where the external electrode exists and a conductor protection layer on the conductor, wherein the stress cushioning layer includes crosslinking acrylonitrile-butadiene rubber having an epoxy resin which is solid at 25° C. and a carboxyl group.
