IPC: H01L21/00
Filed: 1983-05-24
Abstract: PURPOSE:To obtain solid bonding by forming a groove to the bonding surface of an external lead in a flat type semiconductor device. CONSTITUTION:Grooves 8 are formed to the lower surfaces of external leads 2 for an IC. Consequently, since distances are kept among metallic wirings 4 and the leads 2 even in a reflowing method by the pressing of a heater-block, solder sufficient for bonding collects, and solid bonding is obtained. Since sections among the lower surfaces of the leads 2 and the wirings 4 are bonded strongly, the semiconductor device may not depend upon bonding by the side sections of the leads of the IC, the width of the metallic wirings for a substrate can be thinned up to the size close to lead width, and the IC can be mounted while corresponding to the increase of pins for the IC.

When the copying paper on the intermediate tray 48 becomes less as the copying paper is fed, the 1st rocking member 68 is swiveled through the operation of a spring member in the 2nd operation state. Therefore, the feed roller 58 is pressed against the top surface of the uppermost copying paper with relatively large necessary pressure at any time without reference to the quantity of sheets of copying paper on the intermediate tray 48, and consequently copying paper is fed securely as necessary.

Filed: 1982-05-28
Abstract: PURPOSE:To improve the characteristic of resolution in the subscanning direction, by changing the shape of an aperture of picture element in a photoelectric converting section.
