IPC: H01L21/3205
Filed: 1986-12-18
Abstract: PURPOSE:To form a second electrode layer in a self-aligned manner by forming a stepped part in advance on an interlayer insulating film. CONSTITUTION:A first electrode layer 3 of polysilicon is formed on an oxide film 2 on a semiconductor substrate 1, and an interlayer insulating film 4 is formed on the assembly. Then, a resist layer 5 is formed on the insulating film 4, and a stepped part 6 is formed at the insulating film 4 by etching. During this process, only the insulating film 4 at a part where a second electrode layer 10 is to be formed is made thin by etching. Then, a contact hole 7 is made at the insulating film 4 on the electrode layer 3. Then, the whole surface is coated with an electrode material such as Al or the like until the upper face becomes flat. Then the whole surface of the electrode material layer is etched until the surface of the insulating film 4 is exposed. By this process, the second electrode layer 10 is formed in a self-aligned manner in such a way that it is buried by the stepped part 6 of the insulating film 4. In addition, because the selective etching ratio of the insulating film 4 to the resist layer 5 is big, it is possible to execute a minute processing.

Abstract: PURPOSE:To remove contaminants containing carbon or the like from a compound semiconductor crystal substrate without roughening the surface thereof, by heat-treating the substrate in a pre-deposition chamber at a high temperature in a short period of time while it is irradiated with molecular beams of a material that can be removed most easily from among the components of the compound semiconductor crystal substrate. CONSTITUTION:A substrate exchanging chamber 1 is evacuated to about 10<-7>-10<-8> torr. Then, a gate valve 12 is opened so that a GaAs substrate is transferred into a pre-deposition chamber 2. The pressure in the chamber 2 is held at about 10<-9> torr, and As molecular beams are emitted from an As molecular beam source 5 to the GaAs substrate 10. The GaAs substrate 10 is heated by a lamp while it is irradiated with As molecular beams. Then, the temperature of the substrate is lowered spontaneously. The GaAs substrate 190 is transferred to a deposition chamber 6, in which the substrate 10 is heated again to a temperature of about 680 deg.C so that a semiconductor crystal layer of GaAs/AlGaAs is deposited thereon.

IPC: F21V19/00
Filed: 1991-11-19
Abstract: PURPOSE:To provide a socket for single base lamp, with which a base storage part is held at a position of attaching/detaching the lamp without using a spring, which is easily aligned while packaging, and which offers feeling of lamp attachment/detachment. CONSTITUTION:A single base lamp 5 is inserted at a position of attachment/detachment of the lamp that is situated between a first recessed rib 21 and a second recessed rib 22, while a base storage part 6 is held by an locking arm 11. At the time, when the base storage part is rotated around a rotational connection part 10 while a projection 1 of a base 4 of the single base lamp is being inserted into a recessed part 9, the locking arm passes over the recessed rib 12, and the base storage part is changed from the lamp attachment/detachment position into a mounting position, and the locking arm is engaged with the projection and is stopped therethough, while a base pin is in contact with a contact arm 26. When the single base lamp is to be attached or detached, the base storage part is rotated from the mounting position and the locking arm passes over the recessed rib 1, and the storage part is in the lamp attachment/detachment position, and since the projection will not be engaged with a through-stop arm and is thus not be stopped, the lamp can be easily replaced. If the force is excessively great at the time, the base storage part is sometimes rotated so that the locking arm passes over the recessed rib 22, however, by rotating the base storage part in reverse, it returns to the attachment/detachment position.

Abstract: PURPOSE: To obtain the subject compound having excellent heat resistance and capable of holding a crystalline laminar structure even under a high temperature by mixing a phosphate salt with a tin salt in a molar ratio (the phosphate salt/the tin salt) higher than a specified value, filtering the formed precipitates, washing them, mixing with an aqueous solution of phosphoric acid and subsequently heating at a temperature higher than a specified temperature. CONSTITUTION: An aqueous solution of phosphate salt is mixed with an aqueous solution of tin salt in a molar ratio of the phosphate salt to the tin salt at 0.5 or higher than 0.5 to form precipitates. The formed precipitates are filtered, washed, subsequently mixed with an aqueous solution of phosphoric acid and heated at >=120 deg.C. The molar ratio of >=2 is preferable for getting high yield. If soluble in water, any tin salt, e.g. tin chloride is usable. As the phosphate salt, e.g. disodium hydrogenphosphate is used. As the phosphoric acid, e.g. orthophosphoric acid is used. The obtained crystalline tin phosphate is filtered, washed and dried to obtain the subject compound having BET specific surface area of <=15m<2> /g and a laminar structure having spacing of >=0.65nm.
