    • The invention relates to a lateral DMOS-transistor (10) comprising a MOS-diode made of a semi-conductor material of a first type of conductivity, a source-area (16) of a second type of conductivity and a drain-area (18) of a second type of conductivity which is separated from the MOS-diode by a drift region made of a semi-conductor material of a second type of conductivity which is at least partially covered by a dielectric gate layer (28) which also covers the semi-conductor material of the MOS-diode. The dielectric gate-layer (28) comprises a first region (38) of a first thickness (40) and a second region (42) of a second thickness (44).The first region (38) covers the semi-conductor material of the MOS-diode and the second region (42) is arranged on the drift region. The DMOS-transistor (10) is characterised in that a transition takes place from the first thickness (40) to the second thickness (44) such that an edge area of the drift region which is oriented towards the MOS-diode is arranged below the second area (42) of the gate layer (28). The invention also relates to a method for the production of said types of DMOS-transistors (10).
    • 呈现为具有由第二导电型的第二导电类型的由MOS二极管形成的第一导电类型,源极区(16)和漏区(18)的半导体材料制成的MOS二极管的横向DMOS晶体管(10) 第二导电类型的半导体材料的漂移区至少部分地被也覆盖MOS二极管的半导体材料的栅极电介质层(28)覆盖,栅极电介质层(28)具有第一区域(38) 第一厚度(40)和。 具有第二厚度(44)的第二区域(42),其中第一区域(38)覆盖MOS二极管的半导体材料并且第二区域(42)位于漂移区域上。 所述DMOS晶体管(10)的特征在于,从所述第一厚度(40)上的第二厚度(44)的过渡是这样的,所述漂移区的MOS二极管的边缘区域的已经在第二区域中的对向(42) 栅极层(28)被定位。 此外,呈现了用于制造这种DMOS晶体管(10)的方法。
