    Abstract: The disclosure relates to an n-channel laterally diffused metal-oxide-semiconductor device comprising an n+ source (11) in a p-well region (12) and an n+ drain (21) in an n-well region (22), an n-channel (14) extending between the n+ source (11) and the n-well region (22), and a poly gate (3) having a first part (31) above the channel and spanning the entire channel and a second part (32) extending above a part (24) of the n-well region (22) for forming a gate-to-n-well-overlap. The poly gate (3) is a hybrid n+/p+ structure wherein the first part (31) is an n+ part and the second part (32) is a p+ part.

    Abstract translation: 本公开涉及一种n沟道横向扩散的金属氧化物半导体器件,其包括p阱区域(12)中的n +源极(11)和n阱区域(22)中的n +漏极(21), 在n +源极(11)和n-阱区域(22)之间延伸的n沟道(14)以及在沟道上方跨越整个沟道的第一部分(31)的多晶硅(3)和第二部分 (32),其延伸在所述n阱区域(22)的一部分(24)上方,用于形成栅极到n阱的重叠。 多栅极(3)是混合n + / p +结构,其中第一部分(31)是n +部分,第二部分(32)是p +部分。
