摘要： There is provided an assembly of a light source and an optical detector, each using a vertical cavity surface emitting laser (VCSEL). To control light emission of the VCSEL light source, spontaneous light emitted laterally therefrom is converted into an electrical signal. The optical detector for monitoring light is provided around the light source to supply the feedback electrical signal. The inner surface facing the light source of the optical detector is circular to absorb the spontaneous light and the outer surface thereof is polygonal having a plurality of peaks and valleys. Therefore, most of spontaneous light absorbed in the optical detector is reflected within, not penetrating the outer surface thereof, thereby extending the path of the spontaneous light in the optical detector and increasing the light intensity converted into an electrical signal.

摘要： A semiconductor device and manufacturing method thereof is disclosed in which a connection pad layer for securing a contact margin is formed on a first conductivity-type area whereas electrodes are connected directly through openings on a second conductivity-type area without the connection pad layer. In the method, an insulating layer is formed on the overall surface of a substrate. Using a mask pattern for exposing the first conductivity-type area, the insulating layer placed on an exposed portion is anisotropically etched so that the remaining insulating layer serves as an impurity-implantation preventing mask in a succeeding first conductivity-type impurity implantation step. A material layer for the connection pad layer is formed prior to the impurity-implantation step and patterned after the impurity implantation. In forming the second conductivity-type area, an additional insulating layer is formed, and using a mask pattern for exposing the second conductivity area, selectively and anisotropically etched so that the remaining insulating layer or the mask pattern for exposing the second conductivity-type area serves as an impurity-implantation preventing mask.
