  • Patent number: 8669150
    Abstract: A semiconductor device including a capacitor and a proximate high-voltage gate having a boron-barrier layer that ideally serves as part of both the capacitor dielectric and the (high voltage) HV gate oxide. The boron-barrier layer is preferably formed over a poly oxide layer that is in turn deposited on a substrate infused to create a neighboring wells, and N-well over which the capacitor will be formed, and P-well to be overlaid by the HV gate. The boron-barrier helps to reduce or eliminate the harmful effects of boron diffusion from the P-well during TEOS deposition of the gate oxide material.

  • Patent number: 7553733
    Abstract: A lateral double diffused metal oxide semiconductor (LDMOS) device includes a gate to control the device, a drain coupled to the gate formed in a well of a first type, a source to form a current path with the drain, and a first field oxide region disposed between the gate and the drain. The gate is formed over a first portion of the well of the first type and a channel portion of the well of the second type. The LDMOS also includes a second field oxide region, which is disposed between the edges of the drain and the well of the second type. A dummy polysilicon layer, which is formed to cover approximately one half of the second field oxide with a remaining portion of the dummy polysilicon layer covering a second portion of the well of the second type, reduces the electric field in the drift region.

  • Publication number: 20060049452
    Abstract: A lateral double diffused metal oxide semiconductor (LDMOS) device includes forming a plurality of wells on a semiconductor substrate. The plurality of wells include a first well of a first type, a second well of a second type opposite to the first type, and a third well of the first type. The device includes a gate to control flow from current from a source to a drain. Highly doped regions of the first type provide contacts for the source and the drain. The third well, which is disposed in between the second well, is formed directly below the highly doped region. The third well causes an energy barrier at the source to decrease, thereby resulting in lowering a threshold voltage of the LDMOS device compared to the LDMOS device without the third well.
