  • Configuration of trenched semiconductor power device to reduce masked process
    Patent number: 7960787
    Abstract: A semiconductor power device formed on a semiconductor substrate of a first conductivity type wherein the semiconductor power device includes trench gates surrounded by body regions of a second conductivity type encompassing source regions of the first conductivity type therein. The semiconductor power device further includes trench contact structure having a plurality of trench contacts with trenches extended into the body regions for as source-body contacts and extended into the trench gates as gate contact. The semiconductor power device further includes a termination area wherein a plurality of the trench gate contacts are electrically connected to the source-body contacts.
