Title: Boron diffusing method
Inventor: NAGAYAMA YUKIO
IPC: H01L21/22
Filed: 1978-10-26
Abstract: PURPOSE: To keep B density produced on the surface of a semiconductor substrate constant when diffusing B in a BSG layer into the substrate by applying a heat treatment first at low temperature in a dry O 2  atmosphere and then at high temperature in a wet O 2  atmosphere.  
     CONSTITUTION: A BSG layer is predeposited on the surface of a semiconductor substrate, and a heat treatment is applied at 1,000°C for 15 minutes in a dry O 2  atmosphere flowing at 5l/min. Next, the temperature is raised up to 1,100°C in N 2  atmosphere and as holding 1,100°C, the heat treatment is applied consecutively for 1 hour in the wet O 2  atmosphere at 5l/min. The density becomes 1.2W1.4× 10 19 /cc from redistributing impurities on the surface of the substrate, the surface density thus sharply decreases from 5.0W6.0×10 19 /cc which so stands from lacking such a way of treatment, and an uneven distribution is minimized, too.

Title: Manufacture of electrode plate of lead battery
Inventor: YONEZU WAKICHI
IPC: H01M4/21
Filed: 1990-05-21
Abstract: PURPOSE:To make formation efficiency uniform in the inside of a secondary battery and improve the formation efficiency by mounting an evaporation suppressing body on the flat part of an electrode plate of a most end plate in a layered group of laminated electrode plates. CONSTITUTION:Water and sulfuric acid are added to lead powder and the mixture is kneaded to give a paste and after applying the paste to grids, shaping them into electrode plates, a plurality of the electrode plates are laminated to form a electrode plate-laminated group and then maturation-drying of the laminated group is carried out. The maturation-drying is carried out while an evaporation suppressing body is placed on the flat parts of the most end plates of the laminated group which are exposed to the ambient environment. As a result, moisture evaporation speed in the most end electrode plates is delayed to be the same as those of other electrode plates among the electrode plate-laminated group. Consequently, formation efficiency is made uniform in the inside of a battery and also improved.
