Title: Junction of lead and substrate
Inventor: MASAKI YASUSHI
IPC: H01L23/48
Filed: 1993-12-15
Abstract: PURPOSE:To realize junction of a lead with a higher junction strength by heating the leas which is enhanced in thermal conductivity in the junction direction on the occasion of thermally pressure-bonding the tip of the lead to a semiconductor mounting substrate. CONSTITUTION:A lead 2 which is enhanced in thermal conductivity in the junction direction is heated for thermally pressure-bonding the end portion of the lead 2 to a semiconductor device mounting substrate 1. For instance, a thinner- walled area 17 is formed at the end portion of the lead 2 by eliminating the opposite surface (upper surface) of the junction surface of the lead 2 by the half-etching method, etc. Thereby, a distance from the tip of a heating tool 14 to the junction surface becomes short enhancing thermal conductivity. Accordingly, heat is conducted at a higher rate to the junction surface from the heating tool 14. Moreover, a thermal capacity of the tip of the lead 2 becomes small, resulting in a quick temperature rise. Therefore, tin and gold used for plating the lead 2 and circuit quickly form an eutectic alloy of Au-Sn, followed by formation of a fillet 12 having good wettability to realize higher junction strength of the lead 2.

Title: Image data conversion method
Inventor: HAYASHI SHUJI
IPC: H04N1/46
Filed: 1995-12-04
Abstract: PROBLEM TO BE SOLVED: To provide the method converting black level data and three primary color data into three primary color data. SOLUTION: A DTP system 300 provides an output of C(cyan), M(magenta), Y(yellow) and K(black) data representing a color image. The data are given to a data conversion section 105, in which the data are converted into CT, MT, YT before black data generation processing. Achromatic processing by a color adjustment circuit 41 is applied to the data after conversion to allow an output section 3 to provide a print-output of a monochromatic image. A data conversion section 105 predicts black data generation processing to substitute the C, M, Y, K data to a prescribed conversion equation, from which the CT, MT, YT data are generated. Since the layout or the like is confirmed by a monochromatic output in the stage on the way of block copy making, the cost is reduced.
