    摘要: A semiconductor power device is formed on a semiconductor substrate. The semiconductor power device includes a plurality of transistor cells distributed over different areas having varying amount of ballasting resistances depending on a local thermal dissipation in each of the different areas. An exemplary embodiment has the transistor cells with a lower ballasting resistance formed near a peripheral area and the transistor cells having a higher ballasting resistance are formed near a bond pad area. Another exemplary embodiment comprises cells with a highest ballasting resistance formed in an area around a wire-bonding pad, the transistor cells having a lower resistance are formed underneath the wire-bonding pad connected to bonding wires for dissipating heat and the transistor cells having a lowest ballasting resistance are formed in an areas away from the bonding pad.

    摘要: This invention discloses bottom-source lateral diffusion MOS (BS-LDMOS) device. The device has a source region disposed laterally opposite a drain region near a top surface of a semiconductor substrate supporting a gate thereon between the source region and a drain region. The BS-LDMOS device further has a combined sinker-channel region disposed at a depth in the semiconductor substrate entirely below a body region disposed adjacent to the source region near the top surface wherein the combined sinker-channel region functioning as a buried source-body contact for electrically connecting the body region and the source region to a bottom of the substrate functioning as a source electrode. A drift region is disposed near the top surface under the gate and at a distance away from the source region and extending to and encompassing the drain region. The combined sinker-channel region extending below the drift region and the combined sinker-channel region that has a dopant-conductivity opposite to and compensating the drift region for reducing the source-drain capacitance.
