IPC: C23C18/44
Filed: 1992-01-17
Abstract: A printed wiring board is disclosed, which has one or more copper conductor circuits. It has a palladium coating on at least the copper parts which are provided for mounting components by soldering. A process for the mfr. of the printed wiring board by a pattern plating process or a semi-additive process comprises: (1) forming a Cu pattern by copper electroplating; (2) depositing a Pd coating by electroless plating or Pd electroplating on to the Cu pattern parts; (3) removing the plating resist layer; (4) etching the Cu to be removed; (5) forming a soldering resist pattern. USE/ADVANTAGE - The invention is used in the mfr. of high-density integrated circuits. The Pd coating improves the solderability and protects the copper parts from contamination due to the deposition of solder. In an example, a rolled Cu foil (25 x 225 x 0.3mm) was purified by electrolysis and washed with an acid. A Pd film 0.1 thick was deposited by electroless plating, from a soln. contg. palladium dichloride, ethylene diamine, thiodiglycollic acid, and sodium hydrogen phosphite of pH 8 at 60 deg.C. The coated Cu was washed with water and dried. The solderability was tested before and after heating to 230-250 deg.C. The solderability improved by about 50% compared with a Cu sample without a Pd coaing, both before and after heating

Title: Capacitive potential barrier semiconductor dynamic RAM - comprises matrix of word and bit lines interconnected by memory elements formed from potential barrier-gated capacitors
Inventor: YAMADA TAKASHI
IPC: H01L27/108
Filed: 1992-03-18
Abstract: The memory device comprises a matrix of word/bit lines interconnected by a number of single-bit memory elements, each comprising two back-to-back diodes in series with a capacitor. The memory element matrix is constructed from a substrate of one doping type (1) with parallel rows of second doping type regions (3) that form discrete rows of electrodes. Every other row of electrodes (3b) forms a row of memory element lower capacitor lower plates, while the intermediate rows are connected to a metallic bit line. The other plate of the capacitor is formed from a strip of polycrystalline silicon (5) that also forms the word line and which is separated from the lower plate by an insulating layer (4). When a high potential is applied to the bit line conductor (8) while the word line conductor (5) is held low, charge flows across the electrode/substrate/electrode pn junctions and charges the lower plate of the capacitor, thus storing a logical ``1''. If the arrangement is reversed and a high potential is applied to the word line conductor while the bit line conductor is held low, a reverse charge flows, discharging the lower capacitor plate and storing a logical ``0''. ADVANTAGE - Lower memory element size results in increased memory density.
