Title: Discharge plasma treatment and apparatus therefor
Inventor: YUASA MOTOKAZU
IPC: H05H1/46
Filed: 1996-10-29
Abstract: PROBLEM TO BE SOLVED: To enable partial surface treatment of a substrate with a simple process and apparatus under a pressure near an atm. pressure by arranging this substrate into a treatment space formed of solid dielectric walls pendently installed on the peripheral parts of a pair of counter electrodes disposed in an approximately horizontal direction, packing gases for treatment into this treatment space and impressing pulsed electric fields between these counter electrodes to generate discharge plasma. SOLUTION: The treatment space 11 is formed by pendently installing the solid dielectric walls 4a, 4b so as to enclose the spaces between the upper part electrode 2 and lower part electrode 3 disposed to face each other in the approximately horizontal direction. The apparatus is opened by activating an electrode fixing jig 5 and is closed after the substrate 6 is inserted between the solid dielectric walls 4a, 4b. The gases for treatment are then introduced into the treatment space 11 to substitute the treatment space 11 with the gases for treatment and the maintain the treatment space under the pressure near the atm. pressure. The pulsed electric fields are impressed between the upper part electrode 2 and the lower part electrode 3 facing each other by a power source 1, by which the discharge plasma treatment is executed.  As a result, the treatment is made possible even with the large substrate by the relatively small apparatus.

Patent JP-S63142672-A (JP)
Title: Semiconductor device
Inventor: KANAI AKIRA
IPC: H01L29/73
Filed: 1986-12-05
Abstract: PURPOSE:To prevent a drop in hfE of a substrate-type transistor and to increase BVCEO by a method wherein a p-type diffused layer acting as an emitter is not formed on a p-n junction part composed of a p-type substrate, at a part where an n<+> type buried layer is not formed, and an epitaxial n-layer. CONSTITUTION:When a p-diffused layer 6 acting as an emitter is formed on the surface of an epitaxial n<-> type Si layer 4 acting as a base for a substrate- type pnp transistor, a mask 10 is used so that the pattern for the p<+> diffused layer 6 is shifted to the inner side as compared with an n<+> buried layer 2. The shift LB2 of the position between the edge part of the p<+> diffused layer 6 and the edge part of the n<+> buried layer 2 is equal to 0 or at least smaller than the width LB1 of the base. With this structure, because no auto-doping layer exists directly under the p<+> layer acting as the emitter, this layer is not affected by the auto-doping layer. Accordingly, even when a depletion layer from a p-substrate is extended at the substrate-type pnp transistor, no punch- through phenomenon occurs, a BVCEO withstanding voltage is increased; a yield rate is enhanced sharply. In addition, if the LB2 is made smaller than the LB1, it is possible to prevent a drop in hfE.
