Title: Semiconductor device
Inventor: ENDOU SHIGENARI
IPC: H01L29/872
Filed: 1981-10-01
Abstract: PURPOSE:To obtain a diode which shows less leakage current and is resistive to burning without deterioration of switching speed characteristic by keeping the Si surface concentrations of the Schottky electrode and guard ring to the same level. CONSTITUTION:The epitaxial layer 2 for obtaining the desired characteristic is stacked over the substrate by the existing method and the impurity layer 4 of the conductivity type opposing to that of the layer 2 is formed with the oxide film 3 used as the mask. At this time, surface concentrations of the epitaxial layer 2 of the Schottky region and the quard ring layer 4 are kept in the same level and these are not in ohmic contact with the electrode formed by the post- process. Therby, since the surface concentration of Si at the guard ring is lower, carrier implantation does not occur at the guard ring portion even when a backward voltage is applied and the switching speed is not deteriorated. When the dielectric strength of p-n junction is kept lower than the Schottky dielectric strength by controlling the layer 4, a diode which shows less backward current and is resistant to burning can be obtained.

Abstract: PURPOSE: To obtain products of different sizes simultaneously in a small space, to surely sweep off raw stones contained in a raw material, and to surely remove powdery components such as mud and clay. CONSTITUTION: A pan deck 12 is arranged on the discharge side of a hopper 11. A multi-bed system roll screen 15 is placed on the end side of the deck 12.
