Title: Semiconductor laser element
Inventor: KURONAGA KOUICHI
IPC: H01S5/00
Filed: 1984-10-02
Abstract: PURPOSE:To enable the high-yield mass production of the titled element with a saturable absorption region provided in the resonator, by a method wherein the active layer is close to a layer having saturable absorption characteristic to the degree of action as the combination optical waveguide. CONSTITUTION:The induced emission of light is caused by carrier recombination in the active layer 46. On the other hand, a thin film layer 50 allows no excitation of no injection of minority carriers and has a saturable absorption region for laser beams because of equality in energy band gap to that of the active layer 46. In other words, the titled element is provided with the saturable absorber in its resonator. The LD having the saturable absorber in the resonator oscillates Q-SW short pulses on conditions such as the size of said absorber and the size of internal gain, or holds the property of photo bi-stability. Therefore, incorporating this structure in this element realizes the semiconductor element of self-modulation type and that of photo bi-stability.

Filed: 1982-11-25
Abstract: PURPOSE:To improve the poor contact due to having non-uniformity of film thickness of an insulating film by a method wherein the first vapor-phase grown insulating film is thinly formed, the second vapor-phase growing insulating film is formed creating a buffer action against a polycrystalline silicon film using a method having an excellent ratio of etching selectivity, and an anisotropic etching is performed. CONSTITUTION:After a source and drain region 22 has been formed, the first insulating film 209 is formed in a vapor-phase, and a film thin enough for the size of a contact hole is formed. Then, the first contact hole 211 is provided. Pertaining to the etching to be performed at this time, a method having an excellent ratio of etching selectivity can be used. Subsequently, a polycrystalline silicon film 212 is grown, and a polycrystalline silicon region is formed by performing a photo etching with a proper margine on the first contact. Then, the second insulating film 213 is formed in a vapor-phase, and a contact hole 214 is provided. An anisotropic etching is applied for the above-mentioned etching. As the polycrystalline silicon layer is turned to a buffer layer, there is no possibility of an etching performed on a diffusion layer 202.

Title: Electroluminescence element
Inventor: NAKABACHI YOSHIKI
IPC: H05B33/14
Filed: 1991-07-24
Abstract: PURPOSE:To show a steep L-V characteristic by an external device in an alkaline earth group phosphor showing an essentially gentle luminance voltage characteristic (L-V characteristic). CONSTITUTION:In an electroluminescence element consisting of a glass substrate 1, an ITO film 2, a first insulating film 3, a phosphor layer 4, a second insulating film 6 and an electrode 7, for instance, a varister film 5, is interposed between the phosphor layer 5 and the second insulating film 6.

Title: Photoelectric conversion device
Inventor: UENO TOSHITAKE
IPC: H01L21/82
Filed: 1990-08-07
Abstract: PURPOSE:To correct the signal of a faulty picture element so as to improve the yield by closely arranging at least parts of a plurality of scanning lines to a plurality of adjacent photoelectric conversion elements so that they can be short-circuited to each other. CONSTITUTION:When, for example, the output of a picture element A2 is lower than a normal level, the closer sections of scanning lines S1 and S2 are short- circuited to each other by means of an external means, such as laser light, etc. As a result, the outputs of picture elements A1 and A2 rise to the output of the picture element A2 and the bit omission of the picture element A2 is corrected, since the outputs of the picture elements A1 and A2 become a common value which is the higher value of the two. On the other hand, when the output of the picture element A2 is higher than the normal level, the closer sections of the scanning lines S1 and S2 are short-circuited and a switching means SW2 is disconnected from an output line l, so that the signal of the normal picture element A1 can be outputted when the picture element A1 is selected by means of a scanning circuit and cannot be outputted, but the signal of the picture element A2 can be outputted when the picture element A2 is selected. Thus the bit omission of the picture element A2 is corrected.

Title: Formation of fine pattern
Inventor: MATSUMOTO HIROSHI
IPC: H01L21/3065
Filed: 1987-08-21
Abstract: PURPOSE:To enable patterns smaller, than a minimum pattern size determined by essential characteristics of a used exposure technique to be formed as transfer patterns collectively and stably, by depositing and patterning a solid phase film whose volume expands by modification, and modifying the side faces of the pattern of the solid phase film before transferring the pattern on an underlying structure. CONSTITUTION:A solid phase film 6 is deposited on an underlying structure 1. The solid phase film 6 is such that when it is subjected to a certain modifying process, its modification progresses from the surface while causing expansion in volume. The solid phase film 6 is then patterned by a lithography process followed by an etching process. Then, the side faces of the solid phase film patterns are modified by said modifying process and the pattern in the solid phase film 6 is transferred to the underlying structure 1 by the subsequent etching process. According to an emobodiment, a polysilicon film 6 is formed on the underlying structure 1 through a CVD oxide film 5, and a nitride film 7 is formed thereon. After a blank pattern is formed in the films 6 and 7, a thermally oxidized film 9 is deposited on the side faces of the film 6. The blank pattern reduced in size by the oxide film 9 is then transferred on the CVD oxide film 5.
