摘要： A semiconductor device, and a method of manufacturing the same, containing a high voltage DMOS transistor, a low voltage CMOS transistor, and a bipolar transistor in a single substrate. The steps include forming an isolation layer within the substrate in an isolation region between each of a DMOS region, a CMOS region, or a bipolar region. A first oxide layer of variable thickness is formed on the substrate, a thick second oxide layer is formed on the isolation layer, and a polysilicon layer is formed on both oxide layers. The polysilicon layer is patterned to form gate patterns on the first oxide layer and resistive patterns on the second oxide layer. The gate pattern is then doped but the resistive pattern is undoped. The thickness of the first oxide layer in the DMOS region is greater than the thickness of the first oxide layer in the CMOS region.

摘要： A high voltage semiconductor device includes a source region of a first conductivity type having an elongated projection with two sides and a rounded tip in a semiconductor substrate. A drain region of the first conductivity type is laterally spaced from the source region in the semiconductor substrate. A gate electrode extends along the projection of the source region on the semiconductor substrate between the source and drain regions. Top floating regions of a second conductivity type are disposed between the source and drain regions in the shape of arched stripes extending along the rounded tip of the projection of the source region. The top floating regions are laterally spaced from one another by regions of the first conductivity type to thereby form alternating P-N regions along the lateral dimension.

摘要： Methods of forming vertical trench-gate semiconductor devices include the steps of patterning an oxidation resistant layer having an opening therein, on a face of a semiconductor substrate, and then forming a trench in the semiconductor substrate, opposite the opening in the oxidation resistant layer. An insulated gate electrode is then formed in the trench. The face of the semiconductor substrate is then oxidized to define self-aligned electrically insulating regions in the opening and at a periphery of the patterned oxidation resistant layer. Here, the patterned oxidation resistant layer is used as an oxidation mask so that portions of the substrate underlying the oxidation resistant layer are not substantially oxidized. Source and body region dopants of first and second conductivity type, respectively, are then implanted into the substrate to define preliminary source and body regions which extend adjacent a sidewall of the trench. During the implanting step, the electrically insulating regions are used as a self-aligned implant mask. The implanted dopants are then diffused into the substrate to define source and body regions adjacent upper and intermediate portions of the sidewall of the trench, respectively.
