Title: Crystal growth method
Inventor: TANAKA TOSHIO
IPC: H01L21/208
Filed: 1984-10-31
Abstract: PURPOSE:To make it feasible to control a thin epitaxial layer to be grown by a method wherein the crystal growing thickness of one substrate is made larger than that of the other substrate among two opposing semiconductor substrate. CONSTITUTION:Solution of As 13 saturated with Ga 12 is permeated into the gap between two opposing substrates 9, 10 to slowly cool down the temperature of furnace for resultant epitaxial growing of GaAs on the substrates 9, 10. At this time, the plane directions of substrates 9, 10 are respectively set up to be (2-21) plane and (001) plane while the gap between substrates 9 and 10 is set up not to exceed the diffusion length of solute. Thus a thick GaAs crystal layer 16 may be grown on the substrate 9 while a thin GaAs crystal layer 17 may be grown on the substrate 10 since the growing speed on the (2-21) plane is around three times of that on the (001) plane. Through these procedures, the thin layer 17 may be controlled to be grown by means of selecting said plane directions.

Filed: 1990-08-31
Abstract: PURPOSE:To realize a frequency divider circuit having large frequency dividing ratio by a small-scale circuit by combining and decoding the outputs of plural ring counters having frequency dividing ratios in prime relation to each other. CONSTITUTION:A clock signal CLOCK to be frequency-divided is inputted to four pieces of the ring counters 1 to 4, and these ring counters 1 to 4 connect continuously plural FFs respectively, and simultaneously, they feed back the output of each FF to the FF of a first stage through a NAND gate, and the frequency dividing ratio is determined by the number of pieces of the FFs. The frequency dividing numbers of the ring counters 1 to 4 are 4, 5, 7, 9 respectively, and they are in the relation prime to each other, namely, in the relation that one side is not the integral multiple of other side. The outputs of the ring counters 1 to 4 are inputted to the AND gate 5 of a decoding means, and the output of the AND gate 5 is outputted as the frequency divided output through the FFs 6,7. Thus, a circuit scale can be made small, and in addition, an influence to another circuit can be reduced.
