Abstract: A layout pattern of an implant layer includes at least a linear region and at least a non-linear region. The linear region includes a plurality of first patterns to accommodate first dopants and the non-linear region includes a plurality of second patterns to accommodate the first dopants. The linear region abuts the non-linear region. Furthermore, a pattern density of the first patterns in the linear region is smaller than a pattern density of the second patterns in the non-linear region.

Abstract: A layout pattern of a high voltage metal-oxide-semiconductor transistor device includes a first doped region having a first conductivity type, a second doped region having the first conductivity type, and an non-continuous doped region formed in between the first doped region and the second doped region. The non-continuous doped region includes a plurality of gaps formed therein. The non-continuous doped region further includes a second conductivity type complementary to the first conductivity type.

Abstract: A high voltage metal-oxide-semiconductor (HV MOS) device includes a substrate, a gate positioned on the substrate, a drain region formed in the substrate, a source region formed in the substrate, a first doped region formed in between the drain region and the source region, and a second doped region formed over a top of the first doped region or/and under a bottom of the first doped region. The drain region, the source region, and the second doped region include a first conductivity type, the first doped region includes a second conductivity type, and the first conductivity type and the second conductivity type are complementary.

Abstract: A layout pattern of a high voltage metal-oxide-semiconductor transistor device includes a first doped region having a first conductivity type, a second doped region having the first conductivity type, and an non-continuous doped region formed in between the first doped region and the second doped region. The non-continuous doped region further includes a plurality of third doped regions, a plurality of gaps, and a plurality of fourth doped regions. The gaps and the third doped regions s are alternately arranged, and the fourth doped regions are formed in the gaps. The third doped regions include a second conductivity type complementary to the first conductivity type, and the fourth doped regions include the first conductivity type.
