Title: Bipolar transistor and its manufacture
Inventor: AMANO MASARU
IPC: H01L29/73
Filed: 1999-06-08
Abstract: PROBLEM TO BE SOLVED: To reduce base resistance and the resistance between a base and a collector without increasing an element size and costs and to obtain improved high-frequency characteristics by forming a base electrode in contact with at least either of the upper surface of a base layer and the mesa side of the base layer. SOLUTION: Base electrodes 29a and 29b are brought into contact with the entire surface of a base layer 24a as well as the upper surface of the base layer 24a, and are extended to the outer end across a mesa side surface for formation, thus increasing the contact area between the base layer 24a and the base electrodes 29a and 29b and at the same time increasing a sectional area as compared with the base electrode of a bipolar transistor in conventional structure without increasing the film thickness. Therefore, since base resistance can be reduced without increasing the element size and increasing the film thickness of the base electrodes 29a and 29b, improved high-frequency characteristics can be obtained.

Title: Manufacture of distributed index type rubber optical fiber
Inventor: MINE YOSHIKI
IPC: G02B6/00
Filed: 1990-06-20
Abstract: PURPOSE:To manufacture the distributed index rubber optical fiber continuously even when a clad material and a core material are extruded at the same time by extruding the clad material and core material from a double pipe at the same time and setting the clad material which is extruded from the double pipe only nearby the surface. CONSTITUTION:When the core material 17 is inserted into the inner pipe 15 of the double pipe 10 and the clad material 18 is inserted into the outer pipe 16 of the double pipe 10, a monomer which has a different refractive index from the core material 17 is added to the clad material 18 previously, then the clad material 18 and core material 17 are extruded from the double pipe 10 at the same time. After the core material 17 and clad material 18 are extruded from the double pipe 10 at the same time, the surface of the clad material 18 is irradiated with ultraviolet rays from the ultraviolet-ray lamp of an ultraviolet-ray irradiation device 11 to set only the surface of the clad material 18. Then the core material 17 and clad material 18 are extruded toward a coating tank 12 and taken up by a take-up device 14 through a heating furnace 13, and consequently the monomer in the clad material 18 permeates the core material 17 gradually and is diffused, thereby forming a core which varies in refractive index continuously.

Title: Correcting method of mask
Inventor: KOBAYASHI KEIJI
IPC: G03F1/72
Filed: 1980-11-19
Abstract: PURPOSE:To correct a mask by changing a metal layer on a substrate on a transparent glass into a transparent oxide by annealing using electron beam, laser beam, infrared or ultraviolet rays in heated oxide atmosphere. CONSTITUTION:A fine Cr mask pattern 2 on a glass substrate 1 is radiated by convergent laser beam while controlling atmosphere by O2 gas 3. The O2 gas is heated to keep the substrate at high temperatures to prevent hillock or peeling of a pattern due beam heating. The repetition of the irradiation will prove effective. This annealing evaporates a part of Cr leaving the most part being oxidized and almost transparent. Unnecessary part of the mask is removed as if etched chemically making the correction accurate in a short time.
