Abstract
A novel silicon sensor capable of detecting all three magnetic-field components is presented. The device is based on a vertical Hall structure and has been designed and fabricated in a standard 2 mu m CMOS process. Furthermore, a second test structure was implemented by introducing slight changes to the initial design in order to investigate the possibility of increasing device sensitivity. The results show a linear response to magnetic field in the x-, y-, and z-directions for both devices.<>
