Abstract: PURPOSE:To form wirings of small size by forming a second resist film on a whole circuit substrate including a first resist film disposed on the circuit substrate and a wiring forming region, and forming wirings mainly made of Cu in an accuracy corresponding to the working size of the first opening of the second resist film. CONSTITUTION:In a region not formed with wirings 23C, an interlayer insulating film 23B is disposed on a circuit substrate 23A to form a first resist film 18. Then, second resist films 19 are formed on the region formed with the wirings 23C and the film 18 of the region not formed with the wirings 23C. A first opening (groove) 20A is formed on the film 19 of the region formed with the wirings 23C, and a second opening 20B is formed at the film 19 of the region not formed with the wirings 23C. Then, a metal film 23E mainly formed of Cu is deposited on the whole substrate 23A, the films 19, 18 are then removed, the wirings 23C in the opening 20A remain, and dummy wirings 23D on the film 18 and the metal film 23E on the film 19 are removed.

Filed: 1997-01-17
Abstract: PROBLEM TO BE SOLVED: To prevent drying of a tip part of a supply pipe in an apparatus which supplies a coating liquid to the surface of a material to be treated through the supply pipe and carries out the coating. SOLUTION: In an apparatus to supply a resist to the surface of a wafer supported by a chuck through a supply pipe 8 and apply the resist to the surface of the wafer, a solvent bath 14 to collect a solvent of a resist and a solvent- discharging pipe 16 to discharge the solvent of the resist overflowing out of the solvent bath 14 are installed in a container 12 having an aperture 13 into which the tip part of the supply pipe 8 can be inserted. The aperture 13 is formed at a position out of the upper part of the solvent bath 14. The solvent is prevented from being collected in a prescribed amount or more and moreover the resist dropped through the tip end of the supply pipe never flows in the solvent bath 14.

Title: Semiconductor laser
Inventor: NARUI HIRONOBU
IPC: H01S5/00
Filed: 1990-01-30
Abstract: PURPOSE:To prevent a leakage current from being produced, the current triggering a thyristor, by holding an active layer in a recessed part with a first conductivity type cladding layer and a second conductivity type cladding layer vertically and laterally. CONSTITUTION:A title laser is constructed as a double hetero function structure in which a second conductivity type cladding layer 15 is epitaxially grown on an active layer 14 which is then buried in a first and the second conductivity type cladding layers 13, 15, and constructed as a buried type construction in which the double hetero junction structure is held at its opposite end surfaces directly with a current blocking layer 12 via the first conductivity type cladding layer 13. Accordingly, provided part of the active layer 14 is etched in itself, there is avoided a problem such as production of an oxide film, i.e., the actual layer 14 from being eroded in itself. Hereby, a thyristor is prevented from being switched on owing to a leakage current generated through a current blocking layer to improve optical output characteristics.
