Title: Polishing pressure modulating cmp device
Inventor: JEREMY K STEVENS
IPC: B24B37/04
Filed: 1999-07-29
Abstract: PROBLEM TO BE SOLVED: To flatten a semi-conductor wafer and other work piece by periodically applying the downward or upward force to any one of a wafer pushed to a polishing pad or the polishing pad during the flattening. SOLUTION: Downward or upward force is periodically applied to a wafer or a pad 13. In the case where the force is applied to the pad 13 and the periodical force is interrelated with the relaxing time of the pad, a chemical and mechanical flattening process is remarkably improved. During the operation of the chemical and mechanical flattening process in the normal condition, the periodical force and the compressibility of the pad 13 are interrelated with each other so that a height of the pad 13 is maintained between a compression height 13b expressed with dotted lines 13d, 13e and a compression released height 13c. Height of the pad 13 between the dotted lines 13d, 13e is defined as Hop. Height of the pad 13 is higher than the compression height 13b, and lower than the compression released height 13c.  Chemical and mechanical flattening process is remarkably improved by operating this process within a range Hop of the operation height of the pad 13, and an improved result of flattening can be obtained.

Title: Detector for position of laser pickup head
Inventor: KAWAKAMI HIROSHI
IPC: G11B33/10
Filed: 1981-12-26
Abstract: PURPOSE:To detect an accurate position of a laser pickup head, by providing the contact members which give a short circuit successively to plural conduction patterns on a printed circuit board to an attachment table which shifts the laser pickup head. CONSTITUTION:A pickup head attachment stage 20 which is set in parallel to a turntable attachment table that drives a disk moves on a printed circuit board 17 by a feed gear 18 and in a prescribed direction. The contact members 211 and 212 attached to the stage 20 have a contact with conduction patterns 27-31 attached to the board 17 via plate springs 215 and 216. For instance, if a pickup head 21 is positioned at the most inside circumference of the disk, the stage 20 moves right. Then the member 211 gives a short circuit between the patterns 27 and 30, and the position of the head 21 is displayed to a position display. While the head 21 is moving to the most outside circumference of the disk, the member 212 gives a short circuit successively between the pattern 28 and plural patterns 31 with a display of the head 21. Thus the position of the head 21 is assuredly detected.

IPC: G01S13/76
Filed: 1989-08-21
Abstract: PURPOSE:To reduce the scale of a circuit by accomplishing a making of a report and a detection of signals necessary for the making of report using a microcomputer. CONSTITUTION:A farm ware of a microcomputer 8 performs a counting of a system clock simultaneously with the recording of an SSR video inputted into an RAM. When a video pulse with an interval of 20.3mus is detected in the course of one sweep, a timing thereof is used as bracket signal to pick up a code pulse of 13 bits recorded before the timing as response code of a transponder from the RAM. At the same timing, a value of a counter 4 which is counting a system clock is read to obtain a range signal. The above bracket, code and range signals are inputted into a target detection processing 9 of the microcomputer 8 to accomplish a target detection processing. This achieves significant reduction in the scale of a circuit as compared with a type using a shift register.

Title: Semiconductor device
Inventor: OZEKI NOBORU
IPC: H01L29/72
Filed: 1985-09-27
Abstract: PURPOSE:To hold a distance between an emitter and a base in accordance with a designed value in a semiconductor device having the emitter formed through a polycrystalline silicon to which an impurity is added by coating the partial surface and side of the polycrystalline silicon with a thermal oxide film. CONSTITUTION:A thermal silicon oxide film 7 equivalent to a silicon oxide film 12 formed with holes 8, 10 for forming base of collector electrodes is formed in advance on a polycrystalline silicon 6. Thus, it can prevent an emitter 5 and a base 4 from shortcircuiting due to the displacement of the photoresist positions in the holes 8, 10 after the previous steps to be stably microminiaturized to provide a semiconductor device. Since the film 12 can be matched to the film thickness of the holes 8, 10 for the base and collector electrodes, it can suppress the lateral extension of the emitter hole 9 due to an overetching to the minimum, and can hold a distance between the emitter 5 and the base 4 in accordance with a designed value to effectively prevent them from shortcircuiting.

Title: Bed heating apparatus
Inventor: SHIRATAKE AKIRA
IPC: A47G9/06
Filed: 1988-08-30
Abstract: PURPOSE:To supply the sufficient heat value into a bed even in case a power supply is applied while a temperature sensor is kept in a moisture absorbing state or the bed is benumbed with cold by deciding the subsequent high temperature set state holding periods by a 2nd timer in proportion to the period of time when a heater reaches a high temperature from the application of the power supply. CONSTITUTION:When a power switch 2 is turned on, a microcomputer 4 is reset by a resetting part 10. Then it is decided whether a high temperature set state release switch 12 is pushed or not. If not, a signal is outputted from an output terminal D of the computer 4 via a heater driving part 8 to turn on a thyristor 9. Thus the control is started in a high temperature set state. At the same time, a 1st timer counter starts counting. Then the data on the period of time when a heater reaches a high temperature from the application of a power supply is multiplied by a proportion coefficient alpha. Thus the timer count data is obtained and set at a 2nd timer counter contained in the computer 4. Then the 2nd timer counter is started.

Filed: 1991-08-27
Abstract: PURPOSE:To enable effective circuit protection from low-level static electricity by reducing a threshold voltage value at which a thick film transistor constituting a semiconductor protective circuit turns on. CONSTITUTION:An input/output part of a semiconductor circuit is provided with a MIS type thick film transistor a gate oxide film of which is an element isolating film (LOCOS) 17: this transistor is overlaid with a polysilicon layer 36 as a conductive layer in contact being connected to a bonding pad 32 together with the gate electrode 24. This design makes electrostatic noise 34 impressed directly to this polysilicon layer 36 to shorten distance up to a channel region. Therefore, the lower center of the LOCOS 17 is channeled even at a relative low voltage. On the other hand, lower both ends of the LOCOS 17 is channeled by the effect of electric fields due to the gate electrode 24. This process makes all the regions under the gate oxide film channeled to short-circuit a drain 12 and a source 13 with the result that electrostatic noise escapes from the source to the ground.
