IPC: H01L23/52
Filed: 1989-10-04
Abstract: PURPOSE:To restrain the generation of protrusions in metal wiring, and obtain a highly reliable semiconductor integrated circuit with high yield, by a method wherein the heat treatment after metal wiring is patterned is performed after an insulating film is formed so as to cover the metal wiring. CONSTITUTION:The following processes are included; a process wherein a metal wiring film 3 is stuck on a substrate 1 and then shaped into a metal wiring having a specified pattern, a process wherein an insulating film 5 is formed so as to cover the metal wiring, and a process wherein heat treatment is performed in an atmosphere containing hydrogen. For example, after functional elements like a transistor and the like are formed on a P-type Si substrate 1, a silicon dioxide film 2 is grown, and contact holes for connecting the functional elements are formed. An Al film 3 is formed and shaped into a specified pattern. After a silicon dioxide film 5 is formed so as to cover the Al film 3, heat treatment at 350-450 deg.C is performed in an atmosphere containing hydrogen, and the contact resistance of an N-type diffusion layer 4 and the Al film 3 is decreased. Thus the stabilizing process of a transistor is performed. After that, a silicon nitide film 6 is formed, and an aperture 7 for connection with an outer terminal is formed.

Title: Gamma-ray level gage
Inventor: KASAI SHOZO
IPC: G01F23/288
Filed: 1993-10-20
Abstract: PURPOSE:To reduce a linearity error of a level gage and to improve the measuring accuracy thereof by setting the relation of a length of a plastic scintillator of which the linearity error is small to the length of the plastic scintillator. CONSTITUTION:When the full length of a plastic scintillator is made L and a length of the plastic scintillator used actually is made L0, the full length of L1 is provided on the upper end side and that of L2 on the lower end side so as to lessen an end-part effect. When the full length on the upper end side is made L1=D and that on the lower end side is made L2=D+Dtantheta when the thickness of the plastic scintillator is made D, a linearity error can be made small. In the case when scattering due to a vessel, a liquid or others is large, it is necessary to make an extra length at the lower end be 2D+Dtantheta. In other words, the practical range L0 of the plastic scintillator is made the range obtained by excluding the part of D from the upper end and that of 2D to 3D from the lower end, since an angle of irradiation of a gamma ray is about 45 degrees normally. According to this constitution, the linearity error of a level gage can be reduced to about 1/10.
