Patent JP-S61212064-A (JP)
Title: Semiconductor device
Inventor: OIKAWA SABURO
IPC: H01L21/331
Filed: 1985-03-18
Abstract: PURPOSE:To increase the maximum breaking current, by improving uniformity of turn-off operating timing among unit GTOs in a gate turn-off (GTO) thyristor with a large capacity. CONSTITUTION:A number of unit GTOs 1-1 which have gate electrodes 3 formed so as to surround cathode electrodes 2 are arrayed in a ring shape on the surface of a semiconductor substrate 1. Float gate unit GTOs 1-2 which have cathode electrodes 2 put between main gate electrodes 3 and float gate electrodes 3-1 are arranged in a ring shape furthest from the gate connecting section C1. Since the float gate electrodes 3-1 are connected through connecting float gate electrodes 3-1-1 respectively, potential differences among the gate electrodes of the respective float gate unit GTOs 1-2 are practically zero. Accordingly, the respective units can be uniformed in regard to the breaking current and can be broken at the same timing, and therefore the maximum breaking current can be increased.

Abstract: PURPOSE:To enable a mask width to be automatically set by a method wherein a synchronous part magnifying circuit capable of establishing optionally a pulse width near a vertical synchronous part is provided, and further an error detection circuit capable of judging a phase deviation from a CPU by detecting a phase difference signal of a PLL block is installed. CONSTITUTION:An equalizing pulse contained in a HD (horizontal synchronous signal) is inputted into a PLL block a phase difference equivalent to 1/2 of a horizontal is generated to be a signal e. After time K has elaped from a rise of a VD (vertical synchronous signal), a CPU observes the signal e. In that case, since a point l of the signal e is 'H', a parameter of which a pulse width is magnified to a synchronous magnifying circuit a is established. A pulse width of a signal f is given by N1 to N2. When the signal f is 'L', a mask circuit b is so operated as to mask the HD signal, and a signal of the PLL block C comes to be like R. In that case, an influence of the equalizing pulse disappears, and the PLL is thoroughly locked. Consequently the signal e comes to be always 'L' like a signal' e, and judgement of the point l comes to be 'L'. Therefore, the CPU ends correction.
