Title: Resin-sealed semiconductor device
Inventor: NAKAMURA TAKU
IPC: H01L21/60
Filed: 1989-12-20
Abstract: PURPOSE:To execute an assembly operation without lowering a yield and to comply with many types of lead frames by a method wherein a main part of an inner lead is formed by using a resin film formed of a metal thin-film wiring and a semiconductor element is fixed onto the inner lead via an insulating adhesive layer. CONSTITUTION:Main parts of inner leads 13 are constituted of the following: a resin film 1A such as a polyimide film or the like; and and a metal thin-film wiring 1B such as a copper-foil wiring or the like which is formed on the resin film 1A by a plating operation or an etching operation. In this case, a semiconductor element 11 is fixed directly onto the metal thin-film interconnection 1B on the film 1A by suing an insulating paste 1C; and after that, by using bonding wires 12 the semiconductor element 11 is connected electrically to the metal thin-film wiring 1B on the film 1A and the metal thin-film wiring 1B on the film 1A is connected electrically to a lead frame 15. Thereby, since the fine processing property of an wiring pattern is excellent, the limitation on a package designing operation and on an assembly process of ultramultipin types is reduced, and an assembly operation can be executed without lowering a yield.

Title: Method for forming rough face on surface of thin film
Inventor: KOIZUMI MASUMI
IPC: H01L29/40
Filed: 1993-12-27
Abstract: PURPOSE:To facilitate the formation of a rough surface on the arbitrary surface of a thin film by etching out a Cr film formed on a silicon film, and etching out at least one part of a chromium silicide layer and a silicon film formed at the interface of the silicon film and the Cr film. CONSTITUTION:An SiN film 12 is formed on a glass substrate 11 by a plasma CVD method. Then, an a-Si film 13, wherein impurities are not doped, is formed. Finally, a Cr film 14 is formed by a sputtering method. Then, a chromium silicicle layer 15 is formed at the interface of the a-Si film 13 and the Cr film 14. Then, the Cr film 14 is removed from the entire surface by plasma etching by using mixed gas comprising chlorine and oxygen gas. Thereafter, etching is performed for a specified time by using mixed gas comprising sulfur hexafluoride, chlorine and hydrogen gas. Thus, only the SiN film 12 remains on the glass substrate 11, and the surface of the SiN film 12 becomes irregular. When, the second etching time is long, a size (d) of the surface irregularities becomes large.
