Filed: 1983-09-07
Abstract: PURPOSE:To reduce the channel stopper length substantially by a method wherein the first aperture is formed after selective removal of a masking film on the oxide film of a semiconductor substrate, the second aperture overlapping the first aperture being formed, and the substrates then thermally oxidized. CONSTITUTION:An Si oxide film 2 is formed on the surface of the single crystal semiconductor substrate 1, and a masking material film 3 thereon. The first aperture is formed by selective removal of an Si nitride film 3 with a resist film as a mask, and N type impurities such as As are diffused, resulting in the formation of a high concentration N type region 5, and the Si nitride film 3 is adhered over the entire surface. After selective removal of the film 3, the second aperture is formed at a position of overlap with the first aperture, the film 3 being removed after an Si oxide film 6 is formed on the N type Si 1 at the same part, and a P type region 7 being then formed by diffusion of a P type impurity. A depletion layer 8 expands in the state of actual operation, and accordingly the substantial channel stopper length (m) becomes smaller than the dimension l on the mask, which then leads to the improvement of the characteristic of resolution.

Filed: 1978-12-27
Abstract: PURPOSE: To prevent the bump bottom from being cracked by the heat of bonding by allowing beryllia to be incorporated in the surface protective film or the insulation film between internal wiring layers of the semiconductor pellet.  
     CONSTITUTION: A through hole 5 is made through a protective film 4 on the Al wiring 3 and a bump 8 is provided on the through hole by laminating a metal layer 6 for higher adherance and a metal layer 7 for preventing the diffusion of the metal composing the bump. A beryllia layer 11 is provided under the Al wiring 3 connected to the bump 8 to facilitate the conduction of heat to the beryllia layer 11 from the bump 8. Since the heat conductivity of beryllia is almost the same as that of Al, and the beryllia used for the surface protective film and the internal wiring insulating film of the semiconductor pellet employing Al for the internal wiring 3 allows the isotropical diffusion from the bump 8 of the bonding heat on the pellet surface, with high conductivity, the steep temperature gradient around the  bump is eliminated, thereby generation of crack is also eliminated.
