Title: Method and device for leveling bump of semiconductor element
Inventor: TSUKAHARA NORITO
IPC: H01L21/321
Filed: 1995-02-06
Abstract: PURPOSE: To remarkably reduce the time required for performing a bump leveling process so as to shorten the work time of the production of a semiconductor element by leveling the bumps of the element while the element is attracted to and carried by means of a nozzle after the bumps are formed on the electrodes of the element by using gold wires. CONSTITUTION: A capillary 12 driven in the X-, Y-, and Z-directions by means of a capillary driving section 12a forms bumps 3 in a semiconductor element 2 on a bump forming stage 9 by using gold wires. After the bumps are formed, a nozzle 1 attracts the element 2 by suction from the stage 9 and carries the element 2 to a tray 8a. While the element 2 is carried, the bumps 3 are leveled. Namely, the nozzle 1 approaches the element 2 by maintaining the plane 1c of its attracting surface 1b in parallel with the element 2 and makes the height of the bumps 3 uniform by deforming the front end sections of the bumps 3 by bringing the plane 1c into contact with the front ends of the bumps 3.

Title: Modulation doped hetero junction-type field effect transistor
Inventor: YAMASHITA TATSUYA
IPC: H01L29/80
Filed: 1988-01-28
Abstract: PURPOSE:To obtain excellent characteristics with the capacity between the gate and the source and the source resistance made small by forming a semiconductor layer to which a donor impurity is doped between an electron supply layer and an ohmic contact resistance reduction layer. CONSTITUTION:Between an electron supply layer 3 and an ohmic resistance reduction layer 5 is formed a semiconductor layer 4 made of GaAs to which Si is doped at a density of 2X10<17>cm<-3>. In this way, with a semiconductor disposed between the resistance reduction layer 5 and the supply layer 3, a gate depletion layer is not liable to creep around to the resistance reduction layer 5, and the capacity between the gate and source becomes small. The end part of a source electrode 6 of a gate electrode 8 is brought into contact with the lower end of the side wall of a recessed part 9. So, a two-dimensional electron storage layer depleted by a surface depletion layer is not present between the electrode 8 and the electrode 6, and in spite of the fact that the capacity between the gate and source is small, sufficiently low source resistance can be obtained.

Title: Heat exchanger
Inventor: CHIKU TAKAO
IPC: F28D1/053
Filed: 1982-02-08
Abstract: PURPOSE:To improve the efficiency and to reduce the installation space of the heat exchanger by a method wherein a third fluid passage is provided through passages of fluids which exchange heat between each other, so that the heat exchanging is carried out also with the third fluid. CONSTITUTION:A high temperature gas from a combustor passes through a gas passage 1, whereas water, which is a heated fluid, flows from an inlet 8 through a circulation passage 3 and also through a header 5 on high temperature side, and finally is exhausted to an outlet flange 9. In this while, the heated fluid is heated by the high temperature gas. On the other hand, water, which is a second heated fluid, flows from an inlet 18 through a lower header 15 and a circulation passage 13 to an upper header 14. In this while, the second heated fluid absorbs heat from the first heated fluid in the circulation passage 3 to become hot water, which is accumulated in the upper header 14. When the hot water in the upper header 14 is exhausted out of a water outlet 17, fresh water is refilled from the inlet 18, which will become hot water in due course along the same process as mentioned above. This construction can improve the heat exchanging efficiency and minimize the installation space for the heat exchanger.

Filed: 1990-01-29
Abstract: PURPOSE:To omit the address bus set on a picture bus and to simplify the movement of the picture data by providing an exclusive address counter to a picture processing parts respectively and at the same time setting individually the initial values of address counters. CONSTITUTION:The exclusive address counters 14a - 16a are provided to a picture memory 4a and the picture processing parts 5b and 6b to designate the addresses in these parts 5b and 6b. A main control part 7 sets the independent initial address value to each of counters 14a - 16a. Therefore the picture data on the address designated by its own outer 14a are successively outputted to a picture bus 13 from the memory 4a when the counters 14a - 16a are simultaneously started. Thus the parts 5b and 6b can write the picture data sent out successively to the bus 13 into the designated areas of their own counters 15a and 16a respectively. As a result, the movement of the picture data is simplified and the processing efficiency of the picture data is improved.
