Patent JP-S60263473-A (JP)
Title: Field effect transistor
Inventor: KINOSHITA HARUHISA
IPC: H01L29/10
Filed: 1984-06-11
Abstract: PURPOSE:To realize adjustable threshold voltages and to ensoure optimum, easy operation for each chip by a method wherein a p<+> type semiconductor layer of excellent conductivity implanted with a high concentration of acceptor ions is provided, with the intermediary of a thin semi-insulating layer, on a two-dimensional electron accumulation layer along its surface interfacing with a substrate. CONSTITUTION:Electrons in an n<+> Al0.3Ga0.7As layer 5 doped with Si by modulation are diffused into an undoped GaAs layer 7, to be accumulated therein in the form of two-dimensional gas 8 of electrons. When a field is generated parallel to an interface of said layer 5 by application of a voltage across a source electrode 9 and drain electrode 10, the two-dimensional gas 8 of electrons starts travelling as high-mobility electrons. The rate of the flow of the conductive particles is subject to the voltage applied to a gate electrode 11. Application of the substrate bias voltage for a p<+> GaAs substrate 3 doped with B to the positive or negative side increases or decreases the flow rate and shifts the threshold voltage to the negative or positive side. Accordingly, the best threshold voltage for a chip may be easily chosen to ensure optimum operating conditions for the chip.

Filed: 1996-05-15
Abstract: PROBLEM TO BE SOLVED: To polish a wafer into highly accurate flatness by making uniform the gap between the inside face of a retainer ring and the outer circumferential edge of a wafer.

The dummy 7 is made of Si or SiO similar to the wafer 1, or polytetrafluoroethylene resin of difficult polishing material. By inserting the dummy 7 into the gap between the inside face 6a and the cutout part 1a of the wafer 1, the gap between the inside face 6a and the outer circumferential edge of the wafer 1 becomes uniform even at the cutout part 1a, a polishing head 3 in the vicinity of the outer circumferential edge of the wafer 1 is prevented from swelling, and the swelling quantity can be reduced. Consequently, the wafer 1 can be polished into highly accurate flatness.

Title: Flip chip bonder
Inventor: HORI TAKESHI
IPC: H01L21/56
Filed: 1991-05-27
Abstract: PURPOSE:To provide a flip chip bonder by which bubbles are effectively prevented from staying behind. CONSTITUTION:With rotation of reels 11S and 11T, a flexible substrate 1 is moved onto a substrate stand 14 by the unit block. Along with the movement of the flexible substrate 1, a new part of a film- or paper-made tape 16 is moved onto the substrate stand 14 with rotation of reels 15S and 15T. The tape 16 is located between the substrate 1 and the substrate stand 14. Then, a thermosetting adhesive 7 is applied from an adhesive nozzle 20 onto the substrate 1 located on the substrate stand 14 and an IC chip 3 is mounted by an IC chip supplying arm 18 on the substrate 1 placed on the substrate stand 14. The IC chip 3 is heat-pressed against the substrate stand 14 by a pressing arm 22 which incorporates a heater 23 for securing the IC chip 3 on the substrate 1. When the IC chip 3 is heat-pressed by the pressing arm 22, a part of the tape 16 which corresponds to a bump 6 becomes hollow and the substrate 1 gets deformed accordingly. By deformation of the substrate 1, bubbles generated in the adhesive 7 are pushed out and therefore there is no bubble staying behind in the adhesive 7.

Abstract: PURPOSE:To send out papers in a normal condition, without a separation piece causing to stretch, by mounting the separation piece to a holder by means of fitting bosses with heads provided on the surface of the separation piece into holes drilled on the separation piece mounting side from the paper feeder roller side. CONSTITUTION:Bosses 4a with heads integrated into a separation piece 4 are inserted into around through holes 5a drilled on a holder 5 and the separation piece 4 is firmly secured to the holder 5 because the head portions of the bosses are protruding beyond the holder 5. As a result of constituting such construction, even if paper sheets having large friction 1, such as an art paper, are sent out between a paper feeding roller 3 and an auxiliary roller 9 and the separation piece 4 is applied with tension force, the bosses 4a with heads will be supporting the load because the bosses 4a with heads are inserted into the through holes 5a. Thus paper sheets can be sent out with stability without the separation piece 4 causing to stretch.

Abstract: PURPOSE:To secure the inlet port boost pressure of a hydraulic pump without employing an auxiliary pump by a method wherein the back pressure of a nozzle is converted into kinetic energy in the nozzle while the kinetic energy is converted into a pressure energy in a diffuser without being wasted. CONSTITUTION:A vacuum condition, due to the reduction of the static pressure of operating liquid, is caused near the tip end of the nozzle 6 and the operating liquid is introduced naturally to the proximity of the nozzle 6 from a tank 8 through an operating liquid suction path 9, thereafter, it is supplemented into the stream of the operating liquid, injected from the nozzle 6. In such manner, the pressure energy, due to the back pressure of the nozzle, is converted into the kinetic energy by passing the operating liquid through the nozzle 6 and the kinetic energy is converted into the pressure energy again in the diffuser 11 without being wasted. Accordingly, the inlet port boost pressure of the liquid pump 2 may be secured without employing any auxiliary pump or the like.

Abstract: PURPOSE:To prevent the tension and feed speed of a tape from oscillating, by using a flexible material disc, and by inserting and fixing, in a gap between the disc and a base, a resilient friction plate having a thickness larger than the gap. CONSTITUTION:A tape is wound up on a tape roller 3 and is fed, and a tension arm 1 is rotated around a shaft 9 as a center, overcoming a spring 2 in accordance with the tension of the tape.

Further, in a gap between a disc 4 made of flexible materials and a base 6, there is inserted and fixed a rubber sheet 20 having a thickness slightly larger than the gap. Accordingly, the disc 4 rotated together with the tension arm 1 is made in press-contact with the rubber sheet 20 and is slid thereon, and therefore, the rubber sheet 20 serves as a viscous element with respect to the motion of the arm 1 so that the oscillation of tape tension may be prevented.
