| 摘要 |
An MIS-semiconductor component, includes a substrate having a surface, a first zone of a given first conductivity type embedded in the substrate, a second zone of a given second conductivity type embedded in the first zone, at least one insulating layer disposed on the substrate surface, a contact, and an auxiliary zone surrounding at least part of the contact and being of the second conductivity type and more heavily doped than the second zone. The at least one insulating layer and the second zone have a hole formed therein. The contact is connected to the first zone through the hole and is electrically connected to the second zone through the hole and the auxiliary zone.
