High voltage resistant edge structure for semiconductor components

The invention relates to a high voltage resistant edge structure in the edge region of a semiconductor component which has floating guard rings of the first conductivity type and inter-ring zones of the second conductivity type which are arranged between the floating guard rings, wherein the conductivities and / or the inter-ring zones are set such that their charge carriers are totally depleted when blocking voltage is applied. The inventive edge structure achieves a modulation of the electrical field both at the surface and in the volume of the semiconductor body. If the inventive edge structure is suitably dimensioned, the field intensity maximum can easily be situated in the depth; that is, in the region of the vertical p-n junction. Thus, a suitable edge construction which permits a “soft” leakage of the electrical field in the volume can always be provided over a wide range of concentrations of p and n doping.

System and method for detecting defects on reflection surface through visual system

The invention relates to a system and a method for detecting and imaging reflection surface defects on a reflection surface through a blade edge technology. A camera aperture or an external device is arranged to form a physical blade edge structure in an optical path. The physical blade edge structure advantageously shields reflection rays from an illuminated reflection surface which has a preset slope value, and makes rays deflecting by different slopes reach a visual system camera sensor. Most light reflected from a flat part on a surface is blocked by the blade edge. Most light reflected from a defective slope part is reflected to an entrance aperture. An illumination beam forms a certain angle relative to the optical axis of the camera, to provide an incidence angle which is proper for an examined surface. The surface can be static or move relative to the camera.
