IPC: H01M10/06
Filed: 1999-07-14
Abstract: PROBLEM TO BE SOLVED: To efficiently conduct formation, even at high specific gravity formation with low efficiency and increase low rate discharge capacity and high rate discharge capacity by keeping electrolyte temperature during current supply in a specified range, and increasing the quantity of supply electricity for formation to specified times the theoretical capacity of a positive electrode active material.

Title: Solid-state image pickup device, and its manufacture
Inventor: YAMANO TOSHIAKI
IPC: H04N5/369
Filed: 1996-07-30
Abstract: PROBLEM TO BE SOLVED: To shade the oblique incident light to a charge transfer part completely by providing a solid-state image pickup device with the first shield film made at the sidewall of a transfer electrode through the first interlayer insulating film and the second shield film made to cover the transfer electrode and the first shield film. SOLUTION: The first shield film 10a and the second shield film 10b are made at the sidewall of a transfer electrode 8, and only the second shield film 10b is made at the topside of the transfer electrode 8, and the thickness of the shield films 10a and 10b at the side wall is large, and also they are of double-layer structure. Then, at the interface between the shield films, needle- shaped crystals are not continuous, so the incident light from oblique direction can be shielded enough, so the incident light never reaches the n-type well layer 5 to serve as charge transfer part, and the third shield film 12 shields the vertical incident light from above the n-type well layer 5 to serve as the transfer part.  Accordingly, the occurrence of smear can be prevented by suppressing only the leakage of the light to the n-type well layer to serve as a charge transfer part of oblique incident light.
