Title: Forming method of electrode of semiconductor device
Inventor: NAGURA HIDEAKI
IPC: H01L21/306
Filed: 1985-09-05
Abstract: PURPOSE:To facilitate the removal of an unnecessary metal film and to improve the operability of manufacture by a method wherein the speed of vapor deposition of a metal film is kept high in the former stage and low in the latter stage when the metal film is formed on the region of a semiconductor substrate inside an opening of a photoresist film. CONSTITUTION:A collector region 2 is formed on the back side of an Si substrate 1, and a base region 4 is formed on the front side thereof, while an emitter region 5 is formed inside the region 4. Thereafter an Si oxide film 3 is formed, a photoresist film 7 is stuck thereon, and those portions of the films 3 and 7 corresponding to the regions 4 and 5 respectively are opened to form respective openings 8 and 9. Next, an Al film 10 is formed with vapor deposition on the surface of the film 7 and in the regions 4 and 5 inside the openings 8 and 9. Then, the film 7 is removed, and a base electrode 12 and an emitter electrode 11 are formed. When the film 10 is formed by vapor deposition in the above-stated process, the speed of vapor deposition is expedited in the initial stage of vapor deposition, and thereby it is made possible to impede the nucleation on the substrate 1 and thus to obtain a desired film thickness. The speed of vapor deposition is slowed down in the latter stage of vapor deposition. Thereby the unevenness of the surface of the film 10 is reduced, and thus wire bonding in a process of fabricating a semiconductor element is facilitated.

Abstract: PURPOSE:To prevent a bloom from occurring by passing air from the lateral direction through the main body, making it possible to supply hot water from the upper part, and disposing an openable and closable seal plate at the upper end. CONSTITUTION:An actuator for a cold period is operated, and driven by interrupting the upper end portion of a passage 3b. By driving a blast fan 14, external air is sucked into a passage 3a from the direction (a) and into a passage 3b from the direction (b). On the other hand, hot water has flowed down from a water sprinkling nozzle 6 to a wet wall system film type filler 2, is robbed of heat by external air passing through the passage 3a, and is cooled and stored in a cold water tank 11. Air which has passed through the passage 3a assumes a high temperature saturated state. Further, the passage 3b is a dry type cooling part of hot water, and external air within the passage 3b is heated, and enters into a space 17, and mixed air is discharged to the outside by a blast fan 14. By setting a relative humidity of mixed air with respect to a dry ball temperature to a predetermined value, whereby it becomes possible to prevent the exhaust air from supersaturating and generating white smoke.
