Vertical hall sensor and method for manufacturing a vertical hall sensor

摘要

A well (2) doped for a conductivity type and provided as the sensor region is formed in a substrate (1) made of semiconductor material. Contact regions (4), arranged spaced apart from one another and doped for the same conductivity type as the well (2), are formed in a cover layer (3) that delimits the region with the conductivity type of the well. The contact areas (4) are electroconductively connected to the well (2) and provided for terminal contacts (6).
