Patent DE-19544725-A1 (DE)
Title: Insulated gate bipolar transistor semiconductor substrate mfr.
Inventor: KIM HO-HYUN
IPC: H01L29/78
Filed: 1995-11-30
Abstract: The method involves the vapour deposition of a first epitaxial layer. This has impurities of a first conductive type of a low density and is formed on a silicon substrate. A high density of impurities of the first type are then implanted in the whole first epitaxial layer. A second epitaxial layer is then formed by vapour deposition. This has a lower density of impurities of the first type.A heat treatment process is then carried out. This adjusts the rate of increase of density of the impurities implanted in the first epitaxial layer. The impurities are preferably N type. The method may also involve forming a thermal oxidation layer on the first epitaxial layer then removing it in the region where the gate is to be formed, leaving a photoconductive layer structure. The remaining oxidation layer is removed after implantation of the high density of impurities.

Patent DE-19634755-A1 (DE)
Title: Headlamp reflector for vehicle
Inventor: GIORDANI MARC
IPC: F21V7/09
Filed: 1996-08-28
Abstract: The wave pattern superimposed on the reflector profile has alternate convex (32) and concave (34) shapes separated by vertical lines (35). The width of each convex section is much greater than the width of the concave sections to provide an overall dispersive effect for the beam. This eliminates hot spots in the beam and reduces dazzle. The reflector is designed to provide a horizontal cut-off for one side of the beam. The other side has a wedge shaped upper extension to illuminate the road signs on the nearside of the road. This effect is produced by a wedge section of reflector with the wave pattern slanted to one side.
