Title: Manufacture of magnetic powder for magnetic recording
Inventor: KAWAI TAKAO
IPC: G11B5/712
Filed: 1985-03-07
Abstract: PURPOSE:To enable Co-deposited iron oxide to be directly manufactured from alpha-FeOOH by forming a MeO2 deposit layer (where Me is a metal having a valence of 4) on the surface of acicular alpha-FeOOH, further forming a deposit layer containing Co ions, and thereafter performing reduction and oxidation. CONSTITUTION:Using acicular alpha-FeOOH as the raw material, a MeO2 deposit layer (where Me is a metal having a valence of 4) is formed on the surface thereof, a deposit layer containing Co ions is further formed, and thereafter reduction and oxidation are performed, thereby forming Co-deposited iron oxide. For instance, when NaOH is added to the aqueous solution of FeCl2 and sodium silicate is added and air is blown into after this solution is stirred, alpha-FeOOH will separate out. When hydrochloric acid is added to this solution, SiO2 is deposited on the surface of alpha-FeOOH. Then, when this solution is stirred after addition of the aqueous solution of CoCl2:FeCl2 and the precipitates are filtered and washed, three-layered grains of the mixed layers of alpha-FeOOH/SiO2/CoFeO4 and (CO, Fe)OOH. When this is calcined at 600 deg.C and then is subjected to reduction treatment under the H2 gas stream, Co-deposited iron oxide is obtained.

Filed: 1983-03-22
Abstract: PURPOSE:To stabilize threshold voltage and element characteristics by reducing impurity concentration with regard to a semiconductor substrate by doping an impurity so that a gate electrode is formed in the same type impurity semiconductor as the substrate. CONSTITUTION:A molybdenum silicide film 14 and a polycrystalline silicon film 13 are etched up to a predetermined pattern shape to form a gate electrode 15 on a gate oxide film 12. The ions of an impurity such as P are implanted to form an ion implantation layer in an active region, and the implanted impurity is activated electrically through heat treatment in an inert gas atmosphere, thus shaping N type source region 16 and drain region 17. The intrinsic levels Ei and Fermi levels EF of both a gate and a substrate are approximately equal because both consist of the same type impurity semiconductor at that time. Accodingly, the impurity may be doped to a channel only by an impurity concentration difference section between the gate and the substrate.

IPC: H01L21/673
Filed: 1982-03-26
Abstract: PURPOSE:To reduce probability of failed wafers due to quartz grains and to prolong life of a jig by a method wherein the jig used for supporting semiconductor wafers in a furnace core tube made of quartz is covered on its surface with a polycrystalline silicon coating. CONSTITUTION:A polycrystalline silicon coating 6 is formed on the surface of a quartz jig body 2 in a thickness of not less than 3,000Angstrom . This is performed, for example, in a manner that monosilane is thermally decomposed under low pressure to be deposited on the surface of the jig 2. The jig surface coated with a polycrystalline silicon film which is hard to be broken as compared with quartz, makes it possible to prevent generation of quartz grains due to rubbing between quartzes when the jig is inserted into a furnace core tube made of quartz at the time of heat treatment for wafers. As a result, quartz grains can be prevented from adhering onto the wafer surface. Also, the polycrystalline silicon coating 6 on the jig 2 can be formed at the reduced cost in a repeated manner, so that life of the jig is prolonged.
