    • A tank-isolated drain extended power device (50, 60, 70, 80) having an added laterally extending heavily doped p-type region (56, 62, 72) in combination with a p-type Dwell (32) which reduces minority carrier buildup. The p-doped regions are defined in a P-epi layer surrounded by a buried NBL region (14) connected with a deep low resistance drain region (16) forming a guardring. This additional laterally extending p-doped region (56,62,72) reduces minority carrier build up such that recovery time is significantly reduced, and power loss is also significantly reduced due to reduced collection time of the minority carriers. The device may be formed as an LDMOS device.

    • A power integrated circuit architecture (10) having a high side transistor (100) interposed between a control circuit (152) and a low side transistor (100) to reduce the effects of the low side transistor on the operation of the control circuit. The low side transistor has a heavily p-doped region (56) designed to reduce minority carrier lifetime and improve minority carrier collection to reduce the minority carriers from disturbing the control circuit. The low side transistor has a guardring (16) tied to an analog ground, whereby the control circuit is tied to a digital ground, such that the collection of the minority carriers into the analog ground does not disturb the operation of the control circuit. The low side transistor is comprised of multiple transistor arrays (90) partitioned by at least one deep n-type region (16), which deep n-type region forms a guardring about the respective transistor array. The guardring isolates minority carriers in one transistor array from another transistor array, and facilitates the collection of the minority carriers therethrough.

    • A thick copper interconnection structure and method for an LDMOS transistor for power semiconductor devices. A large LDMOS transistor is formed of a plurality of source and drain diffusion regions to be coupled together to form the source and drain. Gate regions are formed between the alternating source and drain diffusions. Each diffusion region has a first metal layer stripe formed over it and in electrical contact with it. A second metal layer conductor is formed over a plurality of the first metal layer stripes, and selectively contacts the first metal layer stripes to form a source and a drain bus. A thick third metal layer is then formed over each second metal layer bus, either physically contacting it or selectively electrically contacting it. The thick third level metal is fabricated of a highly conductive copper layer. The thick third level metal bus substantially lowers the resistance of the LDMOS transistor and further eliminates current debiasing and early failure location problems experienced with LDMOS transistors of the prior art. Other devices and methods are described.
    • 一种用于功率半导体器件的LDMOS晶体管的厚铜互连结构和方法。 大的LDMOS晶体管由多个源极和漏极扩散区域形成以耦合在一起以形成源极和漏极。 栅极区域形成在交替的源极和漏极扩散之间。 每个扩散区具有形成在其上并与其电接触的第一金属层条纹。 第二金属层导体形成在多个第一金属层条纹上,并且选择性地接触第一金属层条纹以形成源极和漏极总线。 然后在每个第二金属层母线上形成厚的第三金属层,或者物理地接触它或选择性地电接触它。 厚三层金属由高导电铜层制成。 厚的第三级金属总线大大降低了LDMOS晶体管的电阻,并进一步消除了现有技术的LDMOS晶体管所经历的电流去差和早期故障定位问题。 描述其他设备和方法。

    • A zener diode capable of breakdown at much higher voltages than in the prior art is fabricated by providing a semiconductor substrate of a first conductivity type having an opposite conductivity type first tank disposed therein. The first tank includes relatively lower and relatively higher resistivity portions, the relatively lower doped portion isolating the relatively higher doped portion from the substrate.

In accordance with a further embodiment, the diode includes a semiconductor substrate, a first tank portion disposed in the substrate and a second tank portion disposed in the first tank portion as in the prior embodiments. A first region of first conductivity type is disposed in the second tank portion and extends into the first tank portion. A second region of opposite conductivity type more highly doped than the first tank portion is disposed in the first tank portion and spaced from the first region.
