Title: Manufacture of semiconductor laser
Inventor: YOSHITOSHI KEIICHI
IPC: H01S5/00
Filed: 1984-10-19
Abstract: PURPOSE:To manufacture a semiconductor laser having a block layer with a sufficient thickness readily, by removing the central part of the block layer, which is deposited on a mesa stripe by etching, forming a groove, and providing a first clad layer, an active layer and a second clad layer on the block layer and the groove. CONSTITUTION:On the surface of a first conducting type semiconductor substrate 10, a mesa stripe 11 and a second conducting type block layer 12 are formed by a liquid phase epitaxial growing method. Then only the central part of the block layer, which is deposited on the mesa stripe, is removed by etching. A groove 13 reaching the mesa strip is formed. On the block layer and the groove, a first clad layer 14, an active layer 15 and a second clad layer 16 are sequentially formed. The block layer deposited in this way is thin on the mesa stripe and thick on the other part. The height of the mesa stripe is appropriately determined. Thus the block layer for converging a current, which has a required and sufficient thickness, is obtained. On the mesa stripe, the groove having the sufficiently narrow opening width can be formed readily.

Abstract: PURPOSE:To prevent the generation of a concavity warpage in the ordinary state of a laminated sheet for electricity and at a time of working a printed circuit plate by making the resin amount of glass fabric impregnated with resin in a metallic foil side more than the resin amount of glass fabric impregnated with resin on the side opposite to the metallic foil. CONSTITUTION:The difference of the resin amount of glass fabrics impregnated with resin in both a metallic foil side and the side opposite to the metallic foil is preferably regulated to 50 - 20wt% after drying. In other words, the improvement in the elimination of warpage is difficult when the above-mentioned difference is less than 5% and such a tendency that moldability is deteriorated is caused when the difference of resin amount exceeds 20%. As the paper to be impregnated with resin to be utilized, kraft paper, linter paper and blended paper of kraft and linter, etc., are recommended. As glass fabric to be impregnated with resin, glass woven fabric, glass nonwoven fabric and glass paper, etc., are utilized. As resin to be impregnated theretino, phenolic resin, melamine resin, epoxy resin and unsaturated polyester resin, etc., are utilized and it is desirable that epoxy resin excellent in heat resistance and balance in mechanical strength is adopted. As the metallic foil, each individual metal or alloy of copper, iron, aluminum, nickel and zinc, etc., can be utilized.

Abstract: PROBLEM TO BE SOLVED: To make it possible to indicate the phase locking of a highly flexible PLL which causes nearly zero feedback delays, is hardly immune to substrate noise, and can operate at a wide range of frequencies. SOLUTION: A lock indicator 44 incorporates a detection circuit which detects an increment pulse and a decrement pulse from a phase/frequency detector 10 and, when the pulse widths of the pulses are wider than a prescribed value, generates an actuate signal. When the actuate signal is not detected in a given number of cycles of a reference clock signal, the indicator 44 generates a lock signal. In addition, the detection circuit generates a lock cancel signal when a given number of actuate pulses having a wide width are generated in a larger second number of cycles.
