Title: Manufacture of semiconductor device
Inventor: HIJIKATA YUMIKO
IPC: H01L21/76
Filed: 1998-08-06
Abstract: PROBLEM TO BE SOLVED: To treat a shallow groove formed at the upper edge of the residual section of an etching stopper film surrounding an insulator buried into the groove having element-isolation structure properly by conducting a heat treatment for promoting thermal oxidation of a section buried into the shallow groove of a polycrystalline material with introduction of impurities to the polycrystalline material. SOLUTION: Polysilicon 19 is deposited on a silicon oxide film 14 on a semiconductor substrate 10. Impurities are introduced to polysilicon 19 prior to heat treatment to polysilicon l9 for promoting thermal oxidation for changing polysilicon 19 into an electric insulator. Consequently, polysilicon 19 can be converted surely into silicon oxide including even the section of a shallow groove 17. A heating temperature required for oxidizing polysilicon 19 can also be lowered, and the possibility of the whole semiconductor substrate 10 exposed to a high temperature is also prevented. Accordingly, a specified silicon oxide section can be removed without generating a residual problem due to SOG and various problems due to an etchback.

Filed: 1991-08-09
Abstract: PURPOSE:To realize inexpensively a transmission and a reception means and to enhance the ciphering performance by using an infrared ray as a communication means for the cordless microphone system. CONSTITUTION:A microphone 1 is provided with a sound collection section 2, a main body section 3 and an infrared ray transmission section 4.

Filed: 1988-09-07
Abstract: PURPOSE:To obtain a device easy to control the distance between reflectors and to install in spite of change of the lengths of the arm of a robot and a step part by installing two reflectors in parallel with each other and with a prescribed angle to the incident beam and making them rotatable and air-cooled. CONSTITUTION:An incident laser beam 41a is reflected by a reflector 37 to be changed into a laser beam 41b, further, reflected by a reflector 31, and outgoing in a different direction. Since beam guiding members 33, 36 can be rotated through bearings 34, 35, the outgoing beam 41c of the laser beam 41a can change the outgoing beam 41c round the laser beam 41b by an angle of 360 deg. and, therefore, can be used as a laser beam relay unit of a laser beam machine with a robot. Besides, since the reflectors 31, 37 absorb energy, they generate heat. Consequently, cooled air is taken in from an inlet 11, changes the flowing direction at a projecting part 13, the air is permitted to stay temporarily at staying parts 14, 15 to absorb the heat from the reflectors 31, 37 and discharge it outward from discharging parts 16, 17.

Title: Method of fractional collection of nucleic acid fragment
Inventor: NAGAI KEIICHI
IPC: C07H21/04
Filed: 1993-09-09
Abstract: PURPOSE:To provide a method capable of automating the separation and fractional collection of a mixture of nucleic acid fragments of which characteristics such as a sequence, etc., are not known. CONSTITUTION:After providing a column 4 filled with fine particles 1 to which several kinds of oligonucleotide 3 are bound, a specimen of nucleic acids consisting of multiple nucleic acid fragments is injected into one end of the column together with an eluting liquid 7 at a constant flow rate. The nucleic acid fragments move from a specimen injection port 5 to an elution port 11, while the fragments repeat interactions like hybrid formation with the oligonucleotides bound to the fine particles in accordance with the number of complimentary sequences contained in each of the fragments. Since the time required to move to the other end of the column is longer when the interactions of the nucleotide fragments of the specimen with the oligonucleotides bound to the fine particles are stronger, the separation and fractional collection of the specimen fragments become possible by taking advantage of the above time difference.

Title: Complementary type mos semiconductor device
Inventor: HARA TOSHIO
IPC: H01L27/092
Filed: 1985-10-07
Abstract: PURPOSE:To obtain a complementary type MOS semiconductor device having excellent latch-up resistance by joining sections except a channel-side end section in a source region with a high concentration region while connecting these sections except the channel-side end section by conductors. CONSTITUTION:A P-type region 11, which is formed near a junction section with a source region 3 of a P-type well 2 and has concentration higher than the well 2, extends in the direction of the end section of the anti-channel side with the exception of a channel-side end section in the source region 3, and is connected to a P-type region 10. Consequently, the source region 3 is surrounded by the P-type regions 10, 11 in a high concentration region 12 with the exception of the channel-side end section. When a parasitic transistor constituted of a substrate 1, the well 2 and a drain region 4 is brought to an ON state during the use of a complementary type MOS transistor, the potential of the well 2 rises. Since the resistivity of the high concentration region 12 is small, charges entering the high concentration region 12 are discharged instantaneously to an electrode 8, thus preventing an excess over the fault potential difference of the high concentration region 12 and the source region 13 of potential difference between the region 12 and the region 3. Accordingly, a parasitic thyristor is not also ignited.

Filed: 1992-07-31
Abstract: PURPOSE:To improve the recording and reproducing characteristics of an optical recording disk by forming a substrate protective layer by applying ultraviolet curing resin paint having surface tension smaller than the critical surface tension of a transparent substrate to the surface of the transparent substrate. CONSTITUTION:A substrate protective layer 4 is formed by applying ultraviolet curing resin paint to the surface of a transparent substrate 1 to a film thickness of 3-10mum by spin coating and hardening the paint. In order to make the surface of the substrate protective layer smooth without recessed nor projecting section, ultraviolet curing resin paint having surface tension r1 which is smaller than the critical surface tension gammaC of the substrate 1 is used as the paint to be applied to the surface of the substrate 1. Therefore, the surface of the layer 4 which becomes the incident surface of laser light can be made smooth and the recording and reproducing characteristics of this optical recording disk can be improved.
