Title: Electrode forming method for semiconductor device
Inventor: BABA SEIICHI
IPC: H01L29/812
Filed: 1987-02-19
Abstract: PURPOSE:To prevent resist material from penetrating under an electrode metal, by arranging an electrode metal on a semiconductor substrate by applying a resist layer to a mask, which resist layer is formed on an insulating film on the semiconductor substrate and degenerated from the insulating film. CONSTITUTION:The side surface 14a of a resist layer 14 is degenerated against the resist layer 14 on an insulating film 13 so as to retreat from the side surface 13a of the insulating film 13. An electrode metal 15 is formed on a semiconductor substrate 10 by applying the resist layer 14 to a mask. At the time of forming the metal electrode 15, the tendency that the resist material is taken into a part between the metal electrode 15 and the semiconductor substrate 10 is supressed by the insulating film 13, and a semiconductor device with a stable electrode structure can be obtained. Further, inclusion of resist material between the semiconductor substrate 10 and the electrode metal 15, that is, the contamination due to an organic material can be prevented, so that the increase of contact resistance also can be prevented.

Abstract: PURPOSE:To perform effective operation by a system in which electrolytic bath group consisting of a K2CO3-manufacturing electrolytic bath and a KOH-manufacturing electrolytic bath is so combined that K2CO3 can be manufactured concurrently with the manufacture of KOH and the heat possessed by liquid and gas generated from each electrolytic bath is heat-exchanged with supply liquid to electrolytic baths. CONSTITUTION:The electrolytic bath 1 with the cation-exchange membrane C is for the manufacture of K2CO3, and also the electrolytic bath 1' with the cation-exchange membrane C' is for the manufacture of KOH. Both the baths 1 and 1' are supplied KCl aqueous solution, but the solution to be supplied to the bath 1 is heat exchanged with the return saline solution coming through the path 10 from the anode compartments A and A' of the baths 1 and 1' in the heat exchanger 9. On the other hand, the return slaine solution from the heat exchanger 9 is desalted in the desalination process 2, sent to the raw salt-dissolving process 3 to mix it with the saline solution 4, and then sent to the precipitation process 5. In the cathode compartment B of the bath 1, KOH is produced and then reacted with the supply liquid of the cathode compartment to form a K2CO3-dominated solution which is, in turn, introduced through the path 11 into the KHCO3 formation process 14 and reacted with CO2 from the path 15. Then, the KHCO3 formed is precipitated by its solubility difference, separated by the filtration 16, and then taken out of the path 17.

Title: Purification of indium solution and vapor phase epitaxial growth
Inventor: KONDOU SUSUMU
IPC: H01S5/00
Filed: 1983-03-07
Abstract: PURPOSE:To obtain a thin film of high purity while reducing the time of thermal treatment by a method wherein, when liquid phase epitaxial growth of InP, InGaAs and InGaAsP group crystal is performed using In as a solvent while Al is added to In solution, mainly composed of In, and the thin film is grown by thermal fusion. CONSTITUTION:Al is very difficult to be mixed with In even at the high temperature of 600-800 deg.C and easy to be coupled with O2 and other impurities in In solution at the high temperature. The characteristics of Al like this are utilized. When Al is added to In solution, composed of In as a solvent, Al does not dissolve in this solution and, on the other hand, targets the impurities such as oxygen and sulphur in the solution regardless of the composition of the deposited crystal. Therefore, as compared to the conventional method with which the raw material for thin film growth solution is subjected to the high temperature thermal treatment in vacuum or in a highly pure hydrogen atmosphere for a long period, the thermal treatment period can be markedly reduced and an InGaAs thin film of high purity can be obtained.

Title: Vsb detector

Filed: 1998-02-19
Abstract: PROBLEM TO BE SOLVED: To detect a vestigial sideband VSB modulation signal of a ground wave digital broadcast without deteriorating reception performance of a ground wave digital broadcast receiver. SOLUTION: A filter coefficient writer 5 rewrites a filter coefficient 6 of a filter 7 so that a frequency locking range of a voltage controlled oscillator 8 is widened till field synchronization is taken and the frequency locking range of the voltage controlled oscillator 8 is made narrower after the field synchronization is taken. In this case, the frequency holding range after the field synchronization is taken is made equal to the frequency lock range till the field synchronization is taken. Thus, even when a frequency deviation of the VSB modulation signal is high by making the frequency lock range before detection wide, the signal is surely detected and the deterioration in the detection performance is prevented by making the frequency lock range narrower after the detection.
