IPC: H01L21/225
Filed: 1982-02-10
Abstract: PURPOSE:To reduce the number of required steps and facilitate the control of the surface resistance of a diffused region without any diffusion of undesired impurities due to a rosette and without increasng the diffusion depth in the periphery of a desired impurity-diffused region, by laminating a glass film containing impurities and a polycrystalline silicon film on a desired impurity-diffused region on a semiconductor substrate, and oxidizing the substrate surface not covered with the laminate and the surface of the polycrystalline silicon film, and then effecting the diffusion of the impurities. CONSTITUTION:With the atmosphere changed from wet O2 to dry O2, the temperature is raised and a heat treatment is carried out to diffuse Sb from an antimony glass film 22, thereby forming an N type impurity-diffused region 25.

Particularly, the diffusion toward the silicon substrate 21 is stabilized to make it possible to facilitate the control of the surface resistance value.

Abstract: PURPOSE:To provide a phosphor screen with small dispersion of brightness by manufacturing the phosphor screen in such a manner that specific gravity of phosphor slurry is controlled to increase the specific gravity at the time of large grain size of phosphor and to decrease the specific gravity at the time of small grain size. CONSTITUTION:Applying slurry 2 is stirred in an agitator 1, to pass through a feed hose 4 by a snake pump 3, and applied to an internal surface of a panel 6 by opening an injection three-way solenoid valve 5, and unnecessary applying slurry 2 passes through a return hose 7 to return to the agitator 1. After the internal surface of the panel 6 is all coated with the slurry, by centrifugal force with high speed rotation, the slurry is collected to a collecting pan 11. In this recovery slurry 12, specific gravity and grain size are always measured by an automatic specific gravity control meter 9 and a grain size distribution measuring device 10. Since the specific gravity of the recovery slurry is decreased, in order to hold the specific gravity of the applying slurry 2 to a certain fixed value, high specific gravity slurry 8 of specific gravity higher than the specific gravity of the applying slurry 2 is periodically supplied. Here by measuring grain size of the applying slurry 2, the specific gravity is controlled highly at the time of large grain size and lowly at the time of small grain size.
