Abstract: PURPOSE:To make possible easy control of an impurity concentration profile by a method wherein an inert film on the surface of a semiconductor film on a substrate is removed, gas containing impurity component is fed to an exposed active surface to form an impurity film and the impurities are diffused and activated by a heat treatment. CONSTITUTION:A substrate 1 formed with a silicon single crystal semiconductor film 2 and the like on its surface is set in a vacuum chamber, an inert film 3 on the surface of the film 2 is removed and an active surface 4 is exposed. Then, when gas containing impurity components is fed to the surface 4 in the chamber to form an adsorption layer, which is an impurity film 5, and a heat treatment is performed, a solid phase diffusion is performed using the film 5 as a diffusion source and at the same time, the impurities are activated and implanted in the film 2. By this chemical treatment method which does not depend on an ion implantation method, the control of an impurity concentration profile is easily and reliably performed.

Title: Pressure control valve
Inventor: NISHIDA SHIN
IPC: F25B1/00
Filed: 1997-11-17
Abstract: PROBLEM TO BE SOLVED: To prevent breakage of bellows of a pressure control valve to be applied to a CO2 cycle. SOLUTION: The first sealed space 42 to displace a valve element 37 is formed from the first bellows 41, and the second sealed space 40 whose pressure becomes lower than the first sealed space 42 is provided outside the bellows. Thereby the pressure when a refrigerant leakage is generated becomes greater in the sequence from the flow passage 34, the second space 40, and first space 42. Because the differential pressure between the first space 42 and the outlet side of a heat radiator does not directly act on the first bellows 41, they 41 are prevented from breakage, and also damage to the second bellows 38 can be prevented by lessening the pressure in the second space 40 below the first space 42.
