Title: Semiconductor device and production thereof
Inventor: NAKAMURA TETSUHIRO
IPC: H01L21/60
Filed: 1998-07-16
Abstract: PROBLEM TO BE SOLVED: To prevent contact or breakage of bonding wire at the time of injection and molding of transfer mold by coating a bonding wire connecting a semiconductor chip with a wiring board with insulating resin. SOLUTION: Insulating resin 10 is sprayed, before curing, to cover a bonding wire 8 by means of a spray and then it is cured thus protecting the bonding wire 8 with the insulating resin 10. A low viscosity insulating resin having insulating resistance equal to or higher than that of a transfer mold 9, e.g. epoxy adhesive employing a liquid anhydride, is employed as the insulating resin 10. Subsequently, a semiconductor chip 1 and the wire 8 are sealed with the transfer mold 9. According to the method, short circuit due to contact of bonding wires 8 is eliminated at the time of molding and the bonding wire 8 is protected against breakage because strength thereof is enhanced.

Abstract: PURPOSE:To enable to accurately detect the specific pattern on an element to be read out by delaying a signal obtained by photoelectric conversion in the prescribed time, and comparing it with a photoelectric conversion signal outputted later, thereby preventing the erroneous discrimination. CONSTITUTION:When a mail P is detected by an image sensor 5 at a time t0, the output signal becomes a level V1 of substantially constant value in response to the reflectivity. At this time, the scanning output of the previous N lines is supplied to a quantizing circuit 7 from a delay circuit 6, and this output becomes substantially constant level V1' in response to the DC bias voltage. The output of the sensor 5 becomes the level V2 or V3 at the time t2 or t3 when detecting the upper flap 2a or lower flap 1b. On the other hand, the output of the delay circuit 6 becomes the level V2' or V3' at the time t<1> or t4. The quantizing circuit 7 quantizes on the basis of the outputs of the sensor 5 and the circuit 6. When the sensor 5 is higher than the delay circuit 6, it produces ''1'', and when lower, it outputs ''0''.
