摘要： The present invention relates to an accurate method using laser welding for mounting an optical focusing lens utilized in a semi-conductor laser module for optical transmission and optical amplification through an optical fiber and a laser module so produced. The laser module includes an aligned laser diode, a lens fixture mounting the laser diode, a focusing lens mounted within a lens housing which in turn is mounted by a lens ring to the lens fixture. In the method, the steps include aligning mutual positions between the laser diode and the optical focusing lens in the vertical and horizontal directions so that the magnitude of the optical signal output from the optical fiber is maximized after the distance between the optical focusing lens and the optical fiber is adjusted and fixed to obtain a maximum optical coupling efficiency between the laser diode and the optical fiber. Next a laser-welding step is performed at an interval between the lens housing and the lens ring. The mutual positions between the laser diode and the optical focusing lens are aligned in the vertical and horizontal directions so that the magnitude of the optical signal output from the optical fiber is maximized. Finally a laser-welding step is performed at an interval between the lens fixture and the lens ring.

摘要： A device structure of a LDMOSFET has trench type sinker formed using a trench process. A semiconductor layer of a first conductive type is formed within the device structure. A field area is formed in a trench structure on one side of the semiconductor layer and a gate electrode is formed on a given surface of the semiconductor layer. A channel layer of a second conductive type is formed by laterally diffusion from the field area to a width containing both sides of the gate electrode. The source area of LDMOS is electrically connected with the substrate through the sinker. By a piercing through the source area, the sinker divides the source area into two source areas. This division reduces the parasitic resistance as well as parasitic capacitance. In addition, the device structure eliminates the need for high temperature diffusion process and reduces lateral diffusion of the sinker.
