Patent JP-S5728360-A (JP)
Title: Semiconductor device
Inventor: KUSAKA TERUO
IPC: H01L29/68
Filed: 1980-07-28
Abstract: PURPOSE:To control the transistor characteristic of a horizontal type transistor, by forming an electrode having an MOS structure on the reat face of the substrate of low impurity concentration and having the transistor formed thereon, and applying a voltage to the electrode to change the condition of a depletion layer and consequently a gain. CONSTITUTION:With a substrae 1 having a low impurity concentration used as a base layer, a collector 3 and an emitter 2 of the opposite conductivity type, are diffused and a base electrode 4 is formed between the collector and the emitter to obtain a horizontal type transistor. On the rear face of the substrate 1, a polycrystalline Si layer 6 is deposited through an insulation film 5. The layer 6 is fixed to a package 8 by, for example, a metal solder 7 to obtain an element provided with a gate terminal G. When bias is impressed to the gate G for depleting the substrate 1, the condition of the depletion layer can be changed so that the depletion 9b extended from the rear face connects with a collector depletion layer 9a due to the low concentration of the substrae 1. Therefore, a change of the gain owing to the sucking mechanism of a minority carrier injected into the base (substrate 1) is produced. Accordingly, the transistor charaxteristic can be controlled.

Title: Multilayer injection molding process
Inventor: NISHIKAWA KAZUO
IPC: B29C45/16
Filed: 1987-04-28
Abstract: PURPOSE:To enable the adhesion and good connection of inner and outer layers and the surface smoothness to be improved by a method in which after the resin stock solution for an outer layer has been poured into a cavity, the resin stock solution for an inner layer is poured therein before the curing of the former resin, and the filler with rough surface has been preliminarily mixed with the stock solution for the inner layer. CONSTITUTION:First, the resin stock solution 1 for an outer layer is poured in a cavity A by the volume of prescribed ratio to the cavity capacity, and next, the resin stock solution 2 for an inner layer with which fillers 3...3 are mixed is poured into the cavity A until the cavity is filled. Then the stock solution 2 intrudes into the stock solution 1, and the condition that the former is wrapped in the latter in the cavity 4 is obtained. In this case, since the filler 3...3 included in the stock solution 2 intrudes into both inner and outer layers by straddling the interface (a) of both layers, and especially the surface of the filler 3...3 is rough, the force connecting both layers becomes large. Thus, the synthetic resin molding 4, having a multilayer construction and excellent adhesion and connection property between the outer layer resin and the inner layer resin, may be obtained.
