Abstract

A SSIMT(Suppressed Sidewall Injection Magnetotransistor) sensor with high linearity is presented in this thesis. The prototype is fabricated by using the Hynix 0.6$\mu\textrm{m}$ P-substrate twin-well double poly three-metal CMOS Process. The fabricated SSIMT shows that variation of the collector current is extremely linear by varing the magnetic induction from -200mT to 200mT at I$\_$B/=500${\mu}$A, V$\_$CE/=2V and V$\_$SUB/=5V. The relative sensitivity is up to 120%/T. At B = 0, magnetic offset is about 79mT, there relative sensitivity is 30.5%/T. The nonlinearity of the fabricated SSIMT is measured about 1.4%.
