Title: Liquid epitaxial growing method and its device
Inventor: HACHIMAN SHIGEO
IPC: H01L21/208
Filed: 1978-02-22
Abstract: PURPOSE: To increase the light emitting efficiency, by cutting off the upper part layer of solution by about 1/2 to 3/4 and by adding the impurity for light emission center with the condition in which the slider and the solution upper surface are apart from each other, in the liquid phase epitaxial growing of III to V group.  
     CONSTITUTION: The solution 14 is contained in the package 19, the semiconductor substrate 12 is placed on the concave 13, the hole 17 of the spacer 16 is maved on the substrate. The slider 18 is shifted and the through-hole 20 is moved to the hole 17. In this case, a part of the solution, 14a, is placed on the substrate with a uniform thickness (3 to 5,5mm). In this case, although the impurity undesirable is diffused in the solution, the diffusion speed of the n type inpurity in the substrate 12 cools the solution gradually in the slightly faster diffusion speed than the diffusion speed, forming the first n layer. Next, the spacer is moved, cutting off the upper layer of the solution. When it is put in the solution pool 15 and returned on the substrate again, the residual liquid 14a is reduced in 1/4 to 1/2 thickness. With this condition, the impurity for light emission center is added from the gas hole 20, n layer is formed with temperature decreased, p type impurity is added with constant temperature, and pn inversion is made by adding p type impurity, p layer is made with temperature reduction.

Title: Clock stoppage detecting circuit and semiconductor integrated circuit device provided therewith
Inventor: SUGANO HIROSHI
IPC: G06F1/04
Filed: 1999-01-28
Abstract: PROBLEM TO BE SOLVED: To provide a clock stoppage detecting circuit which does not consume much electric power nor requires complicated design and a semiconductor integrated circuit device provided with the circuit. SOLUTION: When a clock signal stops at a high level, a node 107 is gradually discharged, and a P-channel MOS transistor 110 is gradually turned on, but no-through current will flow, because an N-channel MOS transistor 112 is turned off and a dynamic node 11 is charged. When the clock signal stops at a low level, a node 114 is gradually charged and an N-type MOS transistor 119 is gradually turned on, but no through-current will flow, because a P-channel MOS transistor 117 is turned off causing a dynamic node 118 to be discharged. In addition, the charging of nodes utilized for detecting the stop of the clock signal and discharging from the nodes are performed by utilizing a current larger than the ordinary leakage currents of the MOS transistors.
