IPC: H01L31/04
Filed: 1988-08-25
Abstract: PURPOSE:To form unevenness excellent in reproducibility and controllability on a substrate surface, and improve photovoltaic conversion efficiency, by a method wherein, after etch-pits are formed on the surface of crystal silicon by chemically treating the crystal silicon, the pattern of the etch-pits is transferred on the surface of low melting point glass under a heated state. CONSTITUTION:After a crystal silicon wafer 15 having crystal orientation of (100) face is subjected to surface polishing with diamond paste, pyramid type etch-pits are formed on the surface by chemical treatment. The depth of etch-pit is desirable to be 0.2-0.5mum. A substrate 11 is obtained by transferring the pattern of etch-pit on the surface of low melting point glass under a heating state at 500-600 deg.C. Thereby, uneveness excellent in reproducibility and controllability is formed on the substrate surface, and a solar cell having high photovoltaic conversion efficiency can be constituted.

Abstract: PURPOSE:To make it possible to prepare spindle type calcium carbonate with slight aggregation property in forming and drying, by adding water glass or silica sol to a suspension f calcium hydroxide, and blowing gaseous carbon dioxide into the suspension. CONSTITUTION:Water glass or silica sol in an amount of 1-10pts.wt. expressed in terms of SiO2 based on 100pts.wt. solid Ca(OH)2 is added to a suspension of the Ca(OH)2 in 5-20wt% concentration at 20-50 deg.C, and gaseous carbon dioxide is then introduced into the suspension at >=150l/min/kg Ca(OH)2 flow rate under 1-10kg/cm<2> (gauge pressure). Thus, the spindle type calcium carbonate having 0.05-0.2mum minor axis and 0.5-1.0mum major axis is obtained. The surface of the spindle type calcium carbonate particles is further treated with an organic modifying agent, e.g. an alkali metallic salt of a fatty acid or resin acid, or an inorganic modifying agent, e.g. hydrogen fluoride, sulfurous acid gas (sulfur dioxide), titanium or aluminum. According to the method, the calcium carbonate having improved characteristics as a filler for coated paper or aqueous coating materials is obtained.

Title: Spray plating method of ic lead frame
Inventor: MURATA YASUTO
IPC: H01L23/48
Filed: 1984-10-09
Abstract: PURPOSE:To subject only the wire bonding area to a sure plating treatment by subjecting the chip bonding area and wire bonding area to spray plating then stripping the plating layer of the chip bonding area. CONSTITUTION:A plating liquid is injected from a nozzle 12 to an aperture 11 of the 1st mask body 3 which exposes both of the chip bonding area 9 and wire bonding area 10 of an IC lead frame 8 and masks the other part to form the plating layer to the chip bonding area 9 and the wire bonding area 10.
