Title: Method and apparatus for wire bonding
Inventor: OZAWA ATSUSHI
IPC: H01L21/603
Filed: 1993-06-01
Abstract: PURPOSE:To decrease the area of a part to which a bonding wire is crimped, e.g. the area of a pad on a semiconductor chip. CONSTITUTION:With bonding tools 2a and 2b closed and with the vicinity of the tip of a metal thin wire 1 bitten by the tips of chucks 3a and 3b, the metal thin wire 1 is held. In this condition, first bonding is performed with the tip of the metal thin wire 1 pressed on the to a pad 9 of a semiconductor chip 8 by the bonding tools 2a and 2b. After this, the bonding tools 2a and 2b are opened, and the tips of the chucks 3a and 3b are drawn from the metal thin wire 1, and the grasp of the metal thin wire 1 is released. In this condition, looping of the metal thin wire 1 and second bonding to a lead 10 are performed by the bonding tools 2a and 2b. Accordingly, it becomes possible to reduce the size of the semiconductor chip 8 by the decrease of the area of the pad 9, since a large ball or squeeze is not needed at the tip of the metal thin wire 1 at the time of the first bonding.

Title: Production of refractive index distribution type glass
Inventor: MORITA YUKO
IPC: C03C21/00
Filed: 1995-06-21
Abstract: PURPOSE: To enable production of glass having characteristics suitable for application to an optical system by reheating a prepared refractive index distribution type glass so as to locally change the temperature of the glass and correcting the shape of the refractive index distribution. CONSTITUTION: When refractive index distribution type glass prepared by a sol-gel method is returned from an ion exchange temperature to an ambient temperature, the quenched glass structure is liable to become loose and when the glass is reheated, the density is liable to become high. Therefore, the glass is reheated by locally changing the temperature of glass. For example, the center part of the glass is heated to a temperature enough to change to skeleton structure and the periphery of the glass is subjected to re-heating treatment so as to have such heat distribution as to give a temperature lower than that of the central part. Thereby, changing amount of refractive index toward increase can be made large in the canter part treated at high temperature, while the changing amount of refractive index toward increase is made small in the peripheral part.  Further, re-heating treating reverse to the above method can also be carried out.

Abstract: PURPOSE:To reduce the number of components and to delete a mounting space by setting a diode breakdown strength between the collector and the base of a parasitic transistor generated with a second conductivity type region as a base to the collector-emitter breakdown strength or lower of the transistor. CONSTITUTION:A structure in which a high resistance layer (n<+> type) is extended in a low resistance layer (n<-> type) of a drain electrode 2 side opposed to the contact part(n<+> type, p<+> type) of a source Al electrode 1 is provided, and the extending amount to an n<-> type layer 5 is so set that a parasitic transistor becomes VCEO (SUS) > VCBO.

Title: Ic card and ic module
Inventor: GOKAMI MASAO
IPC: B42D15/10
Filed: 1988-06-24
Abstract: PURPOSE:To prevent the breakage of an IC chip and the cutting of wiring parts caused by stress concentration applied to a substrate by disposing the IC chip and the wiring parts in an area corresponding to a ground part and disposing the wiring parts orthogonally to the longitudinal direction of a card base material. CONSTITUTION:Bonding wires 18 are disposed orthogonally to the longitudinal direction of a card base material (a direction of an arrow L). Furthermore, an IC chip 17 and the bonding wires 18 are both disposed within an area corresponding to a ground part 13a of an external terminal 13. An IC card 10 in use is subjected to a bending action in the longitudinal direction of the card base material 30 as shown by an arrow R. Due to this longitudinally bending action, stress concentration occurs on a substrate 12 in the vicinity of an insulating groove 28b. Since the IC chip 17 and the bonding wires 18 are not affected by this stress concentration, the breakage of the IC chip 17 is prevented. Even if the IC card 10 is subjected to the longitudinally bending action, the bonding wires 18 are never cut.
