Title: Mos type semiconductor device manufacturing method
Inventor: SHINADA KAZUYOSHI
IPC: H01L21/336
Filed: 1978-06-30
Abstract: PURPOSE: To enable a device to be operated at a high speed by reducing its size and highly accumulating it in such a manner as to enable a gate region to selfadjust toward source and drain layers with new and simple treatment.  
     CONSTITUTION: Layers of SiO 2  2, Si 3 N 4  3 and high concentration As added SiO 2  4 are piled on a P -  type Si base plate 1, and it is provided with a tapered hole. When a p - epi-layer is made, a single crystal Si 6 grows on the base plate 1 and a poly Si 7 also grows. And then, it is heat-treated for allowing As of the film 4 to be dispersed to form an N +  layer 7 and a layer 6 is also slightly dispersed. The layer 7 is etched to form layers 7a and 7b, and after the surface of Si layer 6 is turned into p +  type by injection of B, a gate oxide film 8 is prepared. At this time, SiO 2  9 is formed on the layers 7a and 7b. By opening a window on the film 9, electrodes 10∼12 are selectively formed. It is possible, in this manner, to reduce size of the device remarkably, minimize joining capacity between a source layer and a drain layer while eliminating unnecessary joint between them, and therefore, to operate the device at a high speed.
