    Abstract: An embodiment of an N-channel device has a lightly doped substrate in which adjacent or spaced-apart P and N wells are provided. A lateral isolation wall surrounds at least a portion of the substrate and is spaced apart from the wells. A first gate overlies the P well or the substrate between the wells or partly both. A second gate, spaced apart from the first gate, overlies the N-well. A body contact to the substrate is spaced apart from the isolation wall by a first distance within the space charge region of the substrate to isolation wall PN junction. When the body contact is connected to the second gate, a predetermined static bias Vg2 is provided to the second gate, depending upon the isolation wall bias (Vbias) and the first distance.

    Abstract: An N-channel device (40, 60) is described having a lightly doped substrate (42, 42′) in which adjacent or spaced-apart P (46, 46′) and N (44) wells are provided. A lateral isolation wall (76) surrounds at least a portion of the substrate (42, 42′) and is spaced apart from the wells (46, 46′, 44). A first gate (G1) (56) overlies the P (46) well or the substrate (42′) between the wells (46′, 44) or partly both. A second gate (G2) (66), spaced apart from G1 (56), overlies the N-well (44). A body contact (74) to the substrate (42, 42′) is spaced apart from the isolation wall (76) by a first distance (745) within the space charge region of the substrate (42, 42′) to isolation wall (76) PN junction. When the body contact (74) is connected to G2 (66), a predetermined static bias Vg2 is provided to G2 (66) depending upon the isolation wall bias (Vbias) and the first distance (745). The resulting device (40, 60) operates at higher voltage with lower Rdson and less HCI.

    Abstract: An LDMOS field effect transistor (80) provides protection against the inadvertent reversal of polarity of voltage applied across the device. To protect an N-channel device, a floating P-type blocking region (82) is provided surrounding the drain region (32). The blocking region (82) is spaced apart from a body region (28) that forms the diffused channel (34) of the transistor (80). A first gate electrode (36) controls the conductivity of the diffused channel (34) and a second gate electrode (84) controls the conductivity of the surface (35) of the blocking region (82).

    Abstract: An N-channel device (40, 60) is described having a very lightly doped substrate (42) in which spaced-apart P (46) and N (44) wells are provided, whose lateral edges (461, 45) extending to the surface (47). The gate (56) overlies the surface (47) between the P (46) and N (44) wells. The P-well edge (461) adjacent the source (50) is substantially aligned with the left gate edge (561). The N-well edge (45) lies at or within the right gate edge (562), which is spaced a first distance (471) from the drain (48). The N-well (44) desirably includes a heavier doped region (62) in ohmic contact with the drain (48) and with its left edge (621) located about half way between the right gate edge (562) and the drain (48). A HALO implant pocket (52) is provided underlying the left gate edge (561) using the gate (56) as a mask. The resulting device (40, 60) operates at higher voltage with lower Rdson, less HCI and very low off-state leakage. P and N dopants are interchanged to provide P-channel devices.
