Abstract: PURPOSE:To provide a semiconductor device capable of stable operation while eliminating adverse effects of doping on the device by a method wherein a highly doped diamond layer is formed as a supply source of carriers and a low doped diamond layer is formed as a movement region of the carriers. CONSTITUTION:A highly doped P<+> type diamond layer 2 is epitaxially grown on a diamond single-crystal substrate 1 which has been synthesized by using an ultrahigh pressure method; and after that, an undoped diamond layer 3 is grown on the layer 2. Then, a Ti electrode 4 as an ohmic electrode and an electrode 5 as a Schottky electrode are formed on the layer 3 by a vapor deposition method. The highly doped layer 2 is used as a supply source of carriers; the undoped layer 3 is used as a conductive layer of the carriers; the impurity density of the layer is set at 10<18>cm<3> or higher and 10<22>cm<3> or lower; and the impurity density of the layer 3 is set at 10<17>cm<3> or lower. Thereby, it is possible to manufacture a semiconductor device, for high-speed and large-lower use, which is stable against a temperature change, whose carrier mobility is high, which can utilize a high dielectric breakdown voltage, which is resistant to the temperature change and whose heat-resistant property and surroundings- resistant property is excellent.

IPC: C01D5/00
Filed: 1981-08-18
Abstract: PURPOSE:To obtain Glauber's salt having high free flowability and dispersible and soluble easily in cold water, by granulating powdery Glauber salt in the presence of a water-soluble binder and water, and drying and classifying the granules. CONSTITUTION:Powdery Glauber salt is mixed homogeneously with a water- soluble binder such as carboxymethylcellulose, etc. and water at weight ratios of 100:(0.5-10):(5-30), and the mixture is granulated and dried. The granules are classified during the above process so as to make a most part of the product to fall within the range of 20-80 mesh. Since the Glauber salt obtained by this process has high free flowability and contains spaces between the particles, it can be piled up for a long period without causing caking phoenomenon. As the salt can be dissolved in water rapidly, it can be used easily in combination with other materials.
