Title: Manufacture of gallium arsenide epitaxial wafer
Inventor: ISHIDA KAZUMOCHI
IPC: H01L21/205
Filed: 1983-05-17
Abstract: PURPOSE:To grow an N<+> layer without losing the property of an N<-> layer and obtain the desired oscillation characteristics by a method wherein a doping impurity concentration in the growth atmosphere gas falls within a specified range of concentration during the time equivalent to 0.5mum growth after initiating the growth of N<+> layer for forming an ohmic electrode. CONSTITUTION:An epitaxial wafer 112, wherein an N<-> layer is deposited on an N type low resistivity GaAs substrate, is mounted on a heating board 111. The flow rate of the H2S gas (N type impurity), which is diluted with the H2 gas in a reaction vessel 109, is determined to be 30ml/min. for a minute and 30sec from the initiation of the growth of the N<+> layer and then increased to 300ml/ min. linearly for a minute. Thereafter, the flow rate is kept constant up to the termination of the growth. The N<+> layer with a thickness of 3mum is discontinuously formed on the epitaxial wafer 112 in 15min. In this process, after initiating the growth of the N<+> layer for an ohmic electrode, the concentration of the doping impurity existing in the growth atmosphere gas shall fall between 20% or more and 50% or less of the degree by which the desired N<-> layer surface concentration can be obtained during the time equivalent to the growth of 0.5mum.

A measuring fluid introduction passage 24 is formed, one end of which is communicated with a case 7 on the bottom part 22 side and the other end of which is communicated with an inner periphery surface supply passage 13 and the supply holes 23. A measuring fluid discharge passage 25 is formed on the other end side of the body 21. As a result, by eliminating contamination of the measuring fluid, it is possible to improve response characteristic and obtain a high sensitive oscillating type gas density meter.  By disposing the introduction passage 24 and the discharge passage 25, it is possible to reduce passage resistance and pressure drop. As a result, the measurement can be conducted even if differential pressure between input and output is small, and the fluid measured can be recycled, therefore, it is possible to prevent it from being discharged to the atmosphere.

Abstract: PURPOSE: To improve the earthquake resistance performance of a reactor by arranging the leaf spring contact point of a horizontal motion prevention fitment and the protruding tip of a fuel pad on the same horizontal surface and the horizontal surface at a height penetrating the upper edge part of an upper lattice plate. CONSTITUTION: Since the displacement limitation protrusion on the lower outer surface of a channel fastener 15 affects the upper limit of the displacement of a high-stiffness leaf spring 17, a reactor has a sufficient stiffness against a large horizontal outer force. Further, a contact A of the spring 17 and the tip middle point of a thick fuel pad 20 are arranged on a same horizontal surface C and the plane C is arranged at a height for penetrating the upper edge part of an upper lattice plate 7, thus extremely reducing the length of the fastener 15 and obtaining a required spring stiffness.  Namely, the upper portion of a fuel assembly can be strongly pressed against the lattice plate 7 due to the operation between the spring 17 and the pad 20 as a fitment for preventing horizontal motion and a loading structure with a sufficient stiffness can be achieved against a large horizontal outer force, thus greatly improving the earthquake resistance of a reactor core.
