Patent JP-S5698842-A (JP)
Title: Semiconductor device
Inventor: SAKIYAMA KEIZOU
IPC: H01L21/768
Filed: 1980-01-09
Abstract: PURPOSE:To make the properties of semiconductor more stabilized, by forming the silicon nitride film containing excessive Si on the electrode wire on the semiconductor substrate. CONSTITUTION:The N layer is formed on the P type Si substrate 1. Opening window through the insulation film 2, Al wire 4 is formed. The silicon nitride film 5 containing excessive Si is stacked on it by plasma growth, by changing the ratio of mixed gases of SiH4, N2 and NH3 and its volume. The formation of the film 5 is performed at the temperature below 550 deg.C so that any unusual reactions between the Si substrate and wire may not occur. After the above, this undergoes the ohmic contact after heat treatment. As the film 5 contains excessive Si, the Al layer is fed with Si from the film 5, and the amount aborbed from the substrate is considerable decreased. Therefore the P-N junction on the substrate does not wear out and the stabler properties of the semiconductor is obtained.

At the same time, charges are supplied to the surface of a plate-shaped dielectric 16 and strong creeping discharge is performed. By the creeping discharge, plasma of atmospheric elements is generated over the all surfaces of the dielectric 16, and positive and negative ions are irradiated on the surface of a current collecting plate 19, and fats and oils and other foreign matters on its surface are removed. Thereby, high grade of surface cleanliness can be obtained and bonding ability of the current collecting plate with an outer jacket film is increased. Therefore, leakage resistance of a battery is improved.
