Abstract: PURPOSE:To improve transistor driving power, to achieve a high speed and to obtain high reliability, by a constitution, wherein impurity distributions in transistor channel regions, which are formed in the first- and second- conductivity-type element regions on the surface of the first conductivity type semiconductor substrate, are made to be impurity distribution having junctions. CONSTITUTION:In a process, which is close to the initial period for obtaining a CMOS, a polycrystalline silicon film 29 is deposited on the entire surface. After a resist is formed on a well region 22, e.g., phosphorus ions are implanted in the polycrystalline silicon film 29 on a substrate 21 other than the well region 22. Thus, an N-type part is obtained and the resist is removed. After the resist is formed on the substrate 21 other than the well region 22, e.g., boron ions are implanted in the polycrystalline film 29 on the well region 22. A P-type part is obtained and the resist is removed. At a process close to the end, tungsten films 37 are selectively grown on the polycrystalline silicon forming gate electrodes 31 and the like. The gate electrode 31 including the N-type impurities and the gate electrode 31 including the P-type impurities are connected through the tungsten films 37.

Title: Double refraction measuring device
Inventor: IWASAKI JUN
IPC: G01N21/23
Filed: 1990-08-17
Abstract: PURPOSE:To eliminate need for a mechanism, for mechanically and accurately moving a phase compensating plate, by using a method in which a phase difference between pieces of polarization, transmitted a double refractional specimen and mutually orthogonal is measured, and the phase difference is electrically canceled with a phase shifter using an electro-optic effect. CONSTITUTION:Incident light from a semiconductor laser 1 to a light wave-guide passage 4 is made e.g. a TE mode. Applied voltage to the electrodes of a mode converter 3 and a phase shifter 5 is adjusted with a polarization control means in a base 2 so that a laser beam 7 incident to a specimen 8 can be made circularly polarized light. A phase difference between TE and TM modes produced by the double refraction of the specimen 8 is adjusted so that output current from a photodiode 16 can be made zero. The adjustment is made by making feedback to each applied voltage of the phase shifter 5 or a phase shifter 11. Because the relation between applied voltage to the phase shifter and a phase shift quantity is known, reversely a phase difference produced with the specimen 8, that is a double refraction quantity, can be learnt from the value of the applied voltage of the phase shifter as a result of adjusting so as to make output current from the diode 16 zero.
