Title: Mask alignment for manufacturing semiconductor device
Inventor: UMEMURA YOSHIO
IPC: H01L21/30
Filed: 1984-05-21
Abstract: PURPOSE:To make it possible to maintain the original quantity of accuracy even after the process change, by employing for a pattern to be mask-aligned constituted by a polygonal diagram, another diagram which has sides being parallel to straight lines which intersect at a half angle of the apex angle to the apexes. CONSTITUTION:The apex 11 of a pattern to be mask-aligned on a photo mask is altered into the apex 11' owing to a process change difference after the pattern is transcribed and formed on a semiconductor substrate, but the apex 11' is still on the line. Since a case not being properly aligned can be detected by a fact that four, three or two of the apexes being included in the pattern to be mask- aligned are not positioned on the line l or l', setting the accuracy of the mask alignment pattern of the photo mask at an appropriate value such as 2mum or 1mum can attain any alignment precision. In this way, where the pattern to be mask-aligned is transcribed on the semiconductor substrate, it is not affected by the diagram modification which may be produced owing to the process change difference, and thus the quantity of accuracy can be kept at a constant value.

Title: Semiconductor laser
Inventor: YAGI TETSUYA
IPC: H01S5/00
Filed: 1987-04-22
Abstract: PURPOSE:To hardly perform the absorption of a laser light at the end face of a laser and to increase a COD level by doping more than the quantity of P-type inverting a P-type impurity near the end face from the surface of the laser to a level of one half of an N-type second clad layer. CONSTITUTION:An impurity is so doped that a P-type is obtained from the surface of a laser near the end face of the laser to one half of an N-type second clad layer 6. Since a P-type-doped layer near the end face composes a P-N-P structure of this section, the clad layer 6 disposed directly below, a P-type active layer 5 and a P-type first clad layer 4, and a current flowing to the vicinity of the end face is blocked. Thus, it can prevent a laser light from being absorbed due to the heat generation at the end face owing to the current flowing near the end face, a laser light at the end face of a chip is absorbed to increase a so-called COD level in which the end face is damaged. Thus, the COD level can be raised without reducing the thickness of the active layer.
