Abstract: PURPOSE:To prevent the generation of narrow channel effect, by preventing impurity in a channel stopper region from diffusing to the vicinity of the active region surface of a MOS transistor, even in the case where a channel stopper is formed. CONSTITUTION:In a semiconductor substrate 1 of first conductivity type, impurity ion of the same conductivity type as the semiconductor substrate 1 is implanted. On the semiconductor substrate 1, a first oxide film 2 is formed, and thereon an oxide film 3 is formed in order. An unnecessary part of the oxide film 3 is eliminated by photolithography, and a second oxide film 4 is formed by thermal oxidation. In an element isolation region, a part 5 of high impurity concentration which is turned into a channel stopper is formed in the vicinity of a boundary surface between an element isolation oxide film 4 and the semiconductor substrate 1. In the active region of an MOS transistor, said part is formed in a deep part of the semiconductor substrate 1, and the impurity does not diffuse as far as the vicinity of the active region surface.

IPC: H04N7/32
Filed: 1979-09-28
Abstract: PURPOSE:To make it possible to control the occupation rate of a buffer memory by changing states of coding according to the volume of generated information. CONSTITUTION:Variable-length coder 205 receives a coded signal from DPCM coder 214 and outputs a variable-length coded signal and a code-length signal that shows its code length. Next, controller 206 integrates the code-length signal sent from variable-length coder 205 to obtain the volume of generated information up to each sampling point (n) and then compares it to prescribed control characteristics. Consequently, a mode signal at the next sampling point n+1 is determined to control variable-length coding circuit 205. Here, mode signal 1 is assigned to quantization characteristics for a large volume of generated information, mode 2 to quantization characteristics for a small volume of generated information, and mode 3 to quantization characteristics for fixed length. Thus, the occupation rate of buffer memory 207 is controlled. At the reception side, the occupation rate of buffer memory 208 is controlled through the opposite operation.
