摘要:
A method of manufacturing a power switching transistor for a fluid ejection device includes forming a first conductivity type region and a first diffused region within the first conductivity type region. The first diffused region has a first conductivity type and has a greater impurity concentration than the first conductivity type region. A gate is formed and is defined to have a thin oxide region and a thick oxide region. The thick oxide region and a first portion of the thin oxide region are disposed over the first conductivity type region and the thin oxide region is at a defined distance from the first diffused region.
