Then the P well diffusion window of the desired pattern is drilled to film 12 and 14 each. Oxide film 12' is grown through the heat oxidation method at the area to be the P well, and B is ion-injected through film 12'. Film 12' is then grown furthermore after pressed with oxygen and nitrogen and until stage error 18 is eliminated between film 12' and 12 on substrate 11. After this, film 14 is removed by corrosion. With this method, error 18 between film 12 and 12' can be reduced down to 0 to several hundreds Å, which is very advantageous to the subsequent photo resist processes. As film 12 and 12' have not to be removed, and thus the oxide film is not necessary to be removed over the entire surface. As a result, the PN junction never be exposed.

Filed: 1983-04-15
Abstract: PURPOSE:To eliminate the need for attachment of aheater and to miniaturize a drum for video tape recorder by using a coil contained in a direct drive type motor as a heater as well. CONSTITUTION:A drum is constituted with a monolithic structure of an upper drum 1, a lower drum 2 and a motor 5. The motor 5 contains a stator coil 6 and a rotary magnet 7. This motor 5 of a direct drive type drum is not generally energized when the operation of a video tape recorder is stopped since it is originally intended to revolve the drum 1. While, the coil 6 can be energized even when the operation of the video tape recorder is stopped and can generate heat. Thus the coil 6 can substitute a conventional heater 3. Furthermore the coil 6 has a large surface area and can heat up quickly the entire part of the drum in comparison with the heater 3. Then the coil 6 can defrost more quickly than the heater 3 when the condensation is produced.
