ZERO-STRESS ZONES AND CONTROLLED-FRACTURING ZONES IN THE PASSIVATION LAYER OF A SEMICONDUCTOR DEVICE

A method of manufacturing a semiconductor device, such as a power MOSFET, comprising: forming a metal layer, the metal layer including an edge where the metal layer ends; forming a passivation layer at a layer higher than the metal layer; and forming a passivation slot in the passivation layer, wher...

Zusammenfassung:A method of manufacturing a semiconductor device, such as a power MOSFET, comprising: forming a metal layer, the metal layer including an edge where the metal layer ends; forming a passivation layer at a layer higher than the metal layer; and forming a passivation slot in the passivation layer, wherein the passivation slot is at least partially positioned over the metal layer, and wherein the passivation slot divides the passivation layer into multiple regions, wherein each region experiences a reduced tensile stress σSiNx as a result of the passivation slot.
