Hauptsensor

Baby-Sensoren

1) atoll p-stop

2) common p-stop

3) combined p-stop

Muster 1: atoll p-stop Muster 2: common p-stop Muster 3: combined p-stop

Sensordesign• trapezoid• doppelseitig

– spezielle Strukturen notwendig, um Streifen der Rückseite elektrisch zu trennen → „p-stop“

– 3 Muster, je 4 Geometrien• Micron Semiconductor Ltd.
