Abstract

Aiming at providing a semiconductor device advanced in performance of transistors, and improved in reliability, a semiconductor device of the present invention has a semiconductor element, a frame component provided over the semiconductor element, while forming a cavity therein, and a molding resin layer covering around the frame component, wherein the frame component is composed of a plurality of resin films (a first resin film and a second resin film) containing the same resin, and the cavity allows the active region of the semiconductor element to expose therein.

Claims (13)

1. A semiconductor device comprising:

a semiconductor element;

a frame component provided over said semiconductor element, while forming a cavity therein; and

a molding resin layer covering around said frame component;

wherein said frame component is composed of a plurality of resin films containing the same resin, and

said cavity allows the active region of said semiconductor element to expose therein.

2. The semiconductor device as claimed in claim 1 ,

wherein said frame component contains a first resin film risen up so as to surround said active region of said semiconductor element; and

a second resin film provided as a lid component tightly closing the space, surrounded by said first resin film, from the top.

3. The semiconductor device as claimed in claim 1 ,

wherein said first and second resin films are composed of a resin curable by heat and light.

4. The semiconductor device as claimed in claim 1 ,

wherein said resin films contain an epoxy resin.
