Title: Manufacture of electrode of compound semiconductor element
Inventor: ISHIHARA HISAHIRO
IPC: H01L21/28
Filed: 1983-09-12
Abstract: PURPOSE:To prevent deterioration due to the reaction of Au during the heat processing by obtaining an alloy layer by heat processing after formation of vacuum-deposited film of Ti/Pt for electroce formation and by forming thereon a bonding pad through vacuum-deposition of Ti/Au. CONSTITUTION:An electrode ohmic is obtained by forming an alloy layer of Ti 3 and compound semiconductor 5 through selective vacuum-deposition and heat processing of Ti 3 and Pt 2. Thereafter, an isulating layer 4 is formed, the Ti/Pt film is exposed by selectively eliminating a particular portion of a film 4 on the Ti/Pt film and a bonding pad is obtained by vaccum-depositing Ti 6 and Au 1 on such region. According to this method, since Au 1 is not formed during the heat processing, deterioration of element characteristic due to formation of alloy spike because Au passes through a varrier metal and reaches the interface with semiconductor can be eliminated. Moreover, since the electrodes 2, 3 and film 4 are not in contact with each other, any stress resulting from difference of thermal expansion coefficients is not applied, and since the film 4 covers the Ti/Pt up to the end portion, semiconductor surface is not exposed.

Title: Method and device for simulating magnetic flux in rotary magnetic field machine
Inventor: GEORUKU HAINRE
IPC: G01R31/34
Filed: 1982-09-27
Abstract: The machine flux of a rotating-field machine is determined from the digitized values of the machine stator terminal voltages and conductor currents averaged within a sampling period of an associated digital evaluation system. In order to form each component of the machine flux, the average value of a stator terminal voltage of the same phase, reduced by the ohmic voltage drop in that phase of the stator winding of the rotating-field machine, is multiplied by the clock period of the digital evaluation system and by a scaling factor and the average values so formed for each clock cycle are summed up. From the integral so obtained, the digitized value of the conductor current of the same phase averaged within a sampling period of an associated digital evaluation system and appropriately scaled, is substracted. The simulation of the machine flux can thereby be accomplished digitally. Because averaged values of the terminal voltages and conductor currents are used in the method, there are no sampling problems in digitizing the values.
