Abstract: PURPOSE: To evade the occurrence of side-etching at the time of the formation of a protruding electrode by forming the protruding electrode of Ag on a semiconductor substrate surface via base-meterial metal by electrolytic plating and by removing the unneeded part of the base-material metal by etching while covering the surface with metal inferior to Ag and Au.  
     CONSTITUTION: On N-type Si substrate 1, P-type region 4 is formed through selective diffusion and then covered with SiO 2  film 2 and windwo 3 for electrode formation is made. Next, Cr layer 5 as a contact metal layer is vapor-deposited on the entire surface and after thick interposing metal layer 6 of Cu or Ni is vapor-deposited on it by being stacked, reverse-surface electrode 7 is fitted onto the reverse surface of substrate 1. Next, the unneeded part of layer 6 is removed through photoetching and photo resist film 8 is applied here for the protection of layer 5. On layer 6, Ag protruding electrode 9 is formed by electrolytic plating and metal protective film 10 of Zn and Ni inferior to Ag and Au is adhered onto the surface before the unneeded parts of film 8 and layer 5 are removed.

Title: Electrolyzed water and production and use thereof
Inventor: KURIWAKA YOSHIOMI
IPC: C02F1/46
Filed: 1994-07-08
Abstract: PURPOSE:To obtain the perfectly same sterilizing effect as a conventional product using only electrolytic acidic water on an anode side even when electrolyzed water formed by performing electrolysis without providing a diaphragm between an anode and a cathode is used as a mixture as it is without distinction of cathode and anode sides and to enhance the productivity of electrolyzed water. CONSTITUTION:Water is electrolyzed without providing a diagraphm between an anode and a cathode. It is pref. to add a small amt. of salts to water to be electrolyzed in order to enhance the efficiency of electrolysis. The electrolyzed water thus obtained inclines to an alkaline side as compared with pH 2-3 of electrolytic acidic water of a conventional method to become a pH range of about 7-10 but has the same sterilzing effect as conventional acidic water. However, since this electrolyzed water is slightly inferior to effect lasting power, it is more pref. to employ a system arranging an electrolytic cell on the way of the piping of tap water to provide electrodes and performing electrolysis at a time of use to obtain fresh electrolyzed water. Since alkali water on a cathode side discarded up to now can be used as a product, productivity is enhanced.
