Semiconductor sensor for determining position of incident light beam, has receiving unit with conductivity type semiconductor layer formed as receiving surface, and is arranged on another semiconductor layer of another conductivity type

摘要

The semiconductor sensor (20) comprises a receiving unit (22) with a conductivity type semiconductor layer which is formed as a receiving surface, and is arranged on another semiconductor layer of another conductivity type. A strip (24) of the latter conductivity type divides the former semiconductor layer in two receiving areas (26,28).
