Title: Manufacture of semiconductor device
Inventor: SUGIKI TADASHI
IPC: H01L21/288
Filed: 1986-07-17
Abstract: PURPOSE:To obtain a semiconductor device characterized by a low cost and improved reliability, by providing a noble metal layer on the surface of a semiconductor substrate through an ohmic contact layer, performing electrolysis of the surface of the noble metal layer in plating liquid including the ions of the same noble metal, reversing the polarity of a voltage, performing electric plating, thereby forming a uniform rear surface of electrode by few processes. CONSTITUTION:A noble metal layer 8 is provided on the surface of a semiconductor substrate 1 through an ohmic contact layer 7. The surface of the noble metal layer undergoes electrolysis by using plating liquid including the ions of the same noble metal as the noble metal 8. Thereafter, the polarity of a voltage is reversed, and electric plating 9 is performed. For example, the Ti-AuSb layer 7 is formed on the rear surface of a wafer. Then, the surface on the side, where an Ag bump 6 is formed, is covered. The wafer is connected to a positive electrode. A platinum plate is connected to a negative electrode. Ag is plated on the rear surface of the semiconductor substrate 1 in the aqueous solution of AgCN. Then, heat treatment is performed in an N2 atmosphere, and the Ag layer 8 is provided through the ohmic contact layer. Then, the wafer is connected to the positive electrode, and the platinum plate is connected to the negaive electrode, and the electrolysis is performed in the aqueous solution of AgCN. Thus the surface of the Ag layer 8 is cleaned. Then the polarity is immediately reversed, and the plating is performed. Thus the Ag layer 9 is obtained.

IPC: F28D15/02
Filed: 1989-06-30
Abstract: PURPOSE:To surely prevent an overload on a container and contrive the realization of low costs by separately independently providing a working fluid storage tank in which a working fluid in a container is allowed to flow out to store through a communicating connected pipe from a part of the container. CONSTITUTION:In the case where heating operation is performed by an automobile heater 1, a fan 8 is operated while a cylinder 13 is operated to shift a piston 12 to the advanced position shown by a virtual line so as to reduce the volume of a storage tank 9. On the other hand, in the case where heating operation is stopped, the fan 8 is stopped while the cylinder 13 is operated to shift the piston 12 to the retreated position shown by a real line so as to increase the volume of the storage tank 9. As the result, a working fluid in a liquefaction state or in a gasification state in the container of a heat pipe 2 goes out into the storage tank 9 through a communicating connected pipe 10. However, the working fluid having come out in the gasification state is condensed in the storage tank 9 to liquefy so as to store.

Title: Driving system for liquid crystal display element
Inventor: KUROE KANEYOSHI
IPC: G09G3/20
Filed: 1989-06-30
Abstract: PURPOSE:To commonly use LOAD signals and to attain vertical n-times height size display by generating plural pieces of the LOAD signals which are small in the duty ratio of clock pulses before the display data corresponding to all signal side electrodes is carried to registers and starting only the scanning side electrodes. CONSTITUTION:The LOAD signals which are small in the duty ratio of the clock pulses CP are generated before the display data D corresponding to all the signal side electrodes is carried to the registers 22 to start the scanning side electrodes. The 2nd LOAD signal L2 is generated between the 1st LOAD signal L1 and the next 1st LOAD signal L1 before the display data for one line is housed in all the shift registers 22 of an IC 36a for driving the signal side in order to make the double height size display. The scanning side electrodes are subjected to the intermediate starting by generating the LOAD signals of the small duty ratio in such a manner. The n-times height size display is thus executed by utilizing the LOAD signal input terminals for the IC for driving the signal side and the IC for driving the scanning side as it is.
