Abstract: PURPOSE:To obtain a pattern formation method by means of which a very fine pattern composed of a metal or a metal oxide is formed to be a desired thickness by a method wherein a very fine pattern is formed by means of an energy beam by using an amorphous thin film formed of a solution containing a polyacid containing a metal and, after that, the metal or the metal oxide is grown by making use of the very fine pattern as a growth nucleus. CONSTITUTION:By using a solution composed of a polyacid containing a metal, an extremely homogeneous amorphous thin film 1 is formed on a substrate 2 by a coating method or an electrodialytic method. A desired pattern is drawn by using, e.g. an electron beam 3'; after that, a developing operation is executed; a very fine pattern 4 is formed. The amorphous thin film on which the very fine pattern has been formed is heated in a reducing atmosphere; a very fine metal pattern 5 is obtained. When it is heated in an oxidizing atmosphere, a very fine metal oxide pattern is obtained. The substrate on which the very fine pattern has been tormed is placed in a reaction furnace; after that, a metal or a metal oxide is grown by a chemical vapor growth method in a reaction-gas atmosphere while the very fine metal pattern or the very fine metal oxide pattern is used as a growth nucleus. As a result, the very fine pattern composed of the metal or the metal oxide can be formed simply without being limited to a thin film.

Abstract: PROBLEM TO BE SOLVED: To improve the yield of manufacture by setting the laser wavelength of a laser activating section to a specific value, setting the forbidden band width of the waveguide layer in a light projecting section to a value larger than that of the laser activating layer, and transparentizing it against laser oscillation wavelength. SOLUTION: A n-type InGaP layer as a lower clad layer 12 and an InGaAs/ InGaAsP layer as a laser activating layer 13 containing an optical containing layer and a strain quantum well layer, are formed on a n-type GaAs substrate 11. The oscillation wavelength of the laser activating layer 13 is set to 0.8-1.1μm, and the forbidden band width of the waveguide is increased. In addition, a p-type InGaP layer as an upper clad layer 14 and a p-type InGaAs layer as a contact layer 15 are grown. Both the end faces of the laminated body are cleft, and a low-reflection film 23 and a high-reflection film 24 as a light reflecting end face are formed on the light projecting plane in the direction of the arrow marked with 'L', or the direction of light projection.  Since the In component of the waveguide layer in the light projecting section is reduced and the forbidden band width is increased, transparency is obtained against laser oscillation wavelength.
