Title: Cream solder
Inventor: NAKAMURA YUKIO
IPC: B23K35/36
Filed: 1988-10-26
Abstract: PURPOSE:To simply discriminate an eliminated state of a flux by a visual observation by adding an organic substance dyestuff whose color is not dissipated before and after melting, to cream solder. CONSTITUTION:When an organic substance dyestuff added to cream solder is allowed to reflow, it expands together with a flux and the cream solder is melted. Dyestuff used therefor is stable dyestuff which is not decomposed even at a heating temperature at the time of reflow, and also, does not become other compound. In the flux which is left by fleon washing, this dyestuff is dispersed, therefore, by checking up whether this dyestuff exists or not, the residual of the flux can be discriminated even by visual observation.

Title: Solid-state image pickup device and overflow barrier forming method for it
Inventor: HARADA KOICHI
IPC: H01L27/148
Filed: 1996-10-14
Abstract: PROBLEM TO BE SOLVED: To avoid occurrence of a false signal or generation of dark current irregularity, by selectively providing an overflow barrier in part of a solid photographing device forming region. SOLUTION: An overflow barrier 26 is formed only in a region (region surrounded by a chain line) where an effective picture element area 21 and OPB 22 are combined together, and is not formed at a horizontal transfer register 23 or peripheral channel stop portion 27. Thus, the potential profile 41 is simply sloped toward a semiconductor substrate. Because of this, all electrons 37 in this region move to the substrate side of this semiconductor. By doing this, photoelectric converted electron 37 and a dark current n the peripheral channel stop portion 27 are not flowed to a light receiving element or the like at the most outer periphery, so that the false signals (irregularity in image) can be reduced.
