Title: Semiconductor crystal growth method
Inventor: HASHIMOTO AKIHIRO
IPC: H01L21/20
Filed: 1990-11-29
Abstract: PURPOSE:To make it possible to grow a compound semiconductor whose dislocation density is small on a semiconductor substrate by a method wherein, when the compound semiconductor in which lattice is not matched with the substrate is crystal-grown, an intermediate film whose dislocation propagation property is different is inserted into a growth film of the compound semiconductor. CONSTITUTION:A GaAs buffer layer 12 is grown on a Si substrate 11, and a dislocation 14 appears on a GaAs layer 13, which is grown by crystal-growing a GaAs layer 13 on the substrate 11 again due to the difference in the lattice constant, etc., from the substrate 11. Then, a Si film (intermediate film) 15 is grown on the GaAs layer 13 by lowering the temperature of the substrate 11. Finally, the GaAs layer 16 is grown by setting the temperature of the substrate 11 to 600 deg.C in a atmosphere of As. Thus, the Si film 15 has a dislocation propagation property differing from that of the GaAs layer 13 so that the dislocation occurred in the GaAs layer 13 will not be propagated to the GaAs layer 16, thereby making the GaAs layer 16 a high-quality crystal with less dislocation.

IPC: G08B29/02
Filed: 1993-12-28
Abstract: PURPOSE:To find out the abnormality of a detector in early stages by judging that abnormality occurs in the detector when the number of detection signals sent from the detector to a terminal abnormality monitoring device exceeds a threshold value. CONSTITUTION:The terminal abnormality monitoring device 4 outputs a clock start signal from a central processing part 4 to a timer part 47, and starts clock by clearing the timer part 47 and all the signal number storage parts 43, 44, and 45. When a fire signal from the detector 1 is received, the central processing part 42 stores the number in which one is added to the number of signals in the signal number storage part 43 storing the receiving number of detection signals from the detector 1 as the number of reception signals again in the signal number storage part 43. When the nunof reception signals exceeds, for example, the threshold value of 20 times, a terminal abnormality signal outputted from a terminal abnormality signal generating part 8 and the address number of the detector 1 are transmitted to a monitoring center. Simultaneously, a transmission prohibition signal which prohibits the transmission of the detection signal to the center even when it is received from the detector 1 is transmitted to the detector 1.
