IPC: H01L21/76
Filed: 1988-06-09
Abstract: PURPOSE:To remove damage to the surface of a groove, which is caused by Si etching, to eliminate an increase in a collector-substrate parasitic capacity and to contrive the improvement of the operating speed of an element by a method wherein a sacrificial oxide film is provided and after boron ions are implanted in the film, the film is removed. CONSTITUTION:A groove 5 is formed by Si etching and thereafter, the bottom surface and side surface of the groove 5 are sacrificially oxidized and boron ions are implanted beyond this sacrificial oxide film (thermal oxide film) 6. Then, when the film 6 is removed, a thermal oxide film 8 is again formed on the bottom surface and the surface of the groove 5 and moreover, the groove 5 is filled with a poly Si layer 9 to form element isolation regions. Thereby, the contact of a p-type channel stopper layer 7 with an n-type buried layer can be avoided and a collector-substrate parasitic capacity that obstructs the high-speed operation of an element is reduced.

Abstract: PURPOSE:To eliminate the photographic fog in both side end parts of a developing roll in a reversal developing device, by forming a doctor blade into such shape that the toner amount supplied to both side end parts of the developing roll is larger than that to the center part. CONSTITUTION:In a reversal developing device, a backup roll 14 keeps a slight gap between itself and a developing roll 11 to carry a recording medium 3. A DC power source 8 is so connected that a bias having the same polarity as an electrostatic latent image is impressed across the developing roll 11 and the roll 14. The shape of a doctor blade 13 has such taper that both end parts of the doctor blade 13 are not brought into contact with the roll 11, and the toner amount supplied to both end parts is larger than that to the center part. Thus, a stagnant toner 12 generated between the roll 11 and the medium 3 is not thinned on both sides and is made uniform through-out the overall width, and the same development conditions are given to all regions of the medium 3. Therefore, the photographic fog in both end parts is eliminated to obtain a good picture.
