Title: Manufacture of semiconductor device
Inventor: SHIMIZU NOBUO
IPC: H01L21/76
Filed: 1988-08-11
Abstract: PURPOSE:To minimize the bird's beak length and achieve high integration of elements by forming a structure in which polycrystal semiconductors are buried in a semiconductor substrate and selectively subjecting to oxidization. CONSTITUTION:A groove is formed in the element separation area in one main surface of a semiconductor substrate 2. A polycrystal semiconductor 4 is formed in this groove. One main surface other than this groove area is covered with a hardly oxidizable insulation film 7 and the groove which is filled with the polycrystal semiconductor 4 is selectively exposed, subjecting to oxidization with the hardly oxidizable insulation film 7 as a mask and forming a field oxide film 8 in the element separation area. Thus, the plycrystal semiconductor 4 is buried in the semiconductor substrate 2 and oxidization in a direction vertical to the semiconductor substrate 2 can be advanced when a field oxide film is grown and oxidization in a direction parallel to the substrate from the side wall of the polycrystal semiconductor 4 in a direction opposite to the bird's beak can be advanced, therefore the extension of a bird's beak can be suppressed. As a result, the bird's beak length is minimized and by shortening the distance between elements, semiconductor elements can be highly integrated and a semiconductor chip can be made small.

Title: Fault supervising system of multiplex converter
Inventor: SHIMADA MASAYUKI
IPC: H04B1/74
Filed: 1983-10-31
Abstract: PURPOSE:To simplify circuit constitution and to improve reliability by supplying sequentially each input/output signal of an active and a spare multiplex converter to a common signal supervising circuit with a scanning signal to supervise the state of each input/output signal. CONSTITUTION:The input/output signal of multiplex converters 1, 2 is inputted sequentially to a signal supervising circuit 33 by opening sequentially gates 25-32 with the scan signal and supervised (e.g., supervision of presence of a frame signal). If a fault is detected to the input side signal system, since it is not a fault of the multiplex converters, the switching is inhibited. When no fault exists in the input side signal system and a fault is detected only at the output side signal system, relays rl1-8 are switched and the system is changed over to the spare system. In this case, a test signal generator 23 is connected to the active system so as to check the operation.
