    摘要: A semiconductor structure is disclosed. The semiconductor structure includes: a substrate of a first conductivity; a first region of the first conductivity formed in the substrate; a second region of the first conductivity formed in the first region, wherein the second region has a higher doping density than the first region; a source region of a second conductivity formed in the second region; a drain region of the second conductivity formed in the substrate; a pickup region of the first conductivity formed in the second region and adjacent to the source region; and a resist protective oxide (RPO) layer formed on a top surface of the second region. An associated fabricating method is also disclosed.
