Title: Semiconductor device
Inventor: TANIGUCHI AKIHISA
IPC: H01L29/812
Filed: 1990-03-20
Abstract: PURPOSE:To provide a semiconductor device with reduced source inductance by selectively growing an epitaxial layer to leave an ungrown area where a source electrode is formed which is connected with a subwafer on the reverse side. CONSTITUTION:Before an epitaxial layer 2 is formed, an SiO2 film 3 is formed on a subwafer 1 so that epitaxial growth may not occur on the SiO2. The SiO2 film 3 is then removed, and another SiO2 film 3 is formed by CVD. A contact hole is opened in the film 3 by a photographic process, and an electrode 4 is formed in it. As a result, the electrode and the subwafer are connected, with the result of decrease in source impedance. Since the electrode 4 and the subwafer 1 are shorted, the manufacturing cost is reduced, and in addition it is possible to improve high frequency characteristics.

IPC: G11B5/84
Filed: 1988-03-25
Abstract: PURPOSE:To reduce the friction of a magnetic disk so as to give CSS (contact- start-stop) characteristics having no friction and attraction phenomena to the disk by removing the carbon layer produced on the surface of a diamond-like carbon layer when diamond-like carbon layer is formed on a magnetic recording layer. CONSTITUTION:This magnetic disk 7 is composed of a base material 1, hardened ground film 2 formed on the base material 1, magnetic recording layer 3 formed on the film 2, and diamond-like carbon film 4 formed on the magnetic recording layer 3 as the protective film of this magnetic disk 7. In the course of manufacturing this magnetic disk 7, a brittle soft carbon film formed on the surface of the diamond-like carbon film 4 is removed by rubbing the surface of the disk 7 with a wiper for clean room after the diamond-like carbon film 4 is formed. Therefore, a protective film which is high in hardness and has a self- lubricating property and a strong water shedding property is obtained. Thus the frictional force is reduced and friction and attraction phenomena are eliminated. In addition, the CSS characteristics are improved.
