Title: Cutting device
Inventor: UEHARA TSUKASA
IPC: B26D7/02
Filed: 1990-11-09
Abstract: PURPOSE:To perform accurate cutting action in a short time by providing plural number of cutting members, a frame that holds the cutting members and movable, a placing member whereon a member to be cut is placed, and an attraction member that attracts and holds the member to be cut on the placing member. CONSTITUTION:A member 23 to be cut is placed on the electrostatic attraction plate 24 of a placing member 2, and after aligning it with first and second aligners 26, 27, 27' a power switch 25 is pressed to operate the electrostatic attraction plate 24 to attract and lock the member 23 to be cut. A frame 1 is rotated in the direction of an arrow A, and a pressure holder 10 is pressed in the direction of an arrow P to perform cutting action. The power switch 25 is a common momentary switch, and an operator turns it ON, then a pressing member presses the power switch 25 again as the result of lowering of the frame 1, however, it is still in the state wherein it is turned ON exerting no effect on retaining of the member 23 to be cut at the time of cutting. After cutting is finished, the frame 1 is lifted turning it OFF for the first time, thereby adsorption of the member 23 to be cut is released and can be taken out easily.

Title: Wafer rear dielectric,system and method for manufacture of gate oxide capacitance containing injection electron flat gun current control as well as manufactured gate oxide capacitance
Inventor: TERII CHIRAPAKUTSU
IPC: H01L23/60
Filed: 1995-11-22
Abstract: PROBLEM TO BE SOLVED: To optimize the manufacturing yield of semiconductor, by depositing dielectric on a silicon wafer or semiconductor material, in order to protect the silicon wafer or the semiconductor material from damage due to electrostatic discharge in the course of manufacture. SOLUTION: A silicon wafer 320 is set in an equipment 306 to be used for ion implantation. It acts for eliminating one out of two conducting paths existing in the course of ion implantation that a nitride (Si3 N4 ) layer exists between the silicon wafer 320 and rubber mount blocks 304. When the backside dielectric layers exist, only the current path passing a wafer fixing member 310 is left. Since the backside and the side of the wafer are isolated with the nitride dialectic layer, the whole part of the wafer is electrically floated from an implantation equipment retaining disc 306. Thereby voltage difference which generates damage in the silicon wafer 320 can be avoided.

Filed: 1988-11-30
Abstract: PURPOSE:To permit a head to effectively follow tracks in high density by reproducing track deviation information having intervals shorter than those of servo sectors from a part except for a data zone and adding it to a control signal obtained from a position signal as an auxiliary signal.

Title: Large scale semiconductor integrated circuit chip
Inventor: MASUKO KOICHIRO
IPC: H01L21/027
Filed: 1989-11-21
Abstract: PURPOSE:To increase the number of logic circuits contained in one chip by using a same aligner, by exposing circuit layout data which are inscribed in a circumference showing a range where optical aberration satisfies a reference value, has six or more vertexes of even number, and is provided with at least two pairs of facing parallel sides. CONSTITUTION:The inside of a circumference 8 is a region capable of assuring that aberration of a wafer stepper is lower than or equal to a reference value. A shaded region 19 is one where circuit elements are formed, i.e., the effective region of a chip. Even in a case where a same optical system of same wafer stepper is used, the effective chip region which can be used for the arrangement of circuit elements can be increased by about 40%, only by tranforming the external shape of a chip from, e.g. a square into an octagon. When the number of corners of the polygon inscribed in the circumference is increased, the area capable of effectively exposing circuit elements can finally be increased by about 60%. Thereby the chip size can be enlarged up to the limit of wafer stepper capability, and a circuit chip on which many logic circuits can be mounted is obtained.
