摘要： A power semiconductor element having a lightly doped drift and buffer layer is disclosed. One embodiment has, underneath and between deep well regions of a first conductivity type, a lightly doped drift and buffer layer of a second conductivity type. The drift and buffer layer has a minimum vertical extension between a drain contact layer on the adjacent surface of a semiconductor substrate and the bottom of the deepest well region which is at least equal to a minimum lateral distance between the deep well regions. The vertical extension can also be determined such that a total amount of dopant per unit area in the drift and buffer layer is larger then a breakdown charge amount at breakdown voltage.

摘要： A semiconductor device includes a first semiconductor substrate of a first band-gap material and a second semiconductor substrate of a second band-gap material. The second band-gap material has a lower band-gap than the first band-gap material. A heterojunction is formed between the first semiconductor substrate and the second semiconductor substrate substantially in a first plane. The semiconductor device further includes, in a cross-section which is perpendicular to the first plane, a first semiconductor region of a first conductivity type and a second semiconductor region of the first conductivity type both of which extend from the second semiconductor substrate at least partially into the first semiconductor substrate. The first and second semiconductor regions are spaced in the first semiconductor substrate from each other in a direction parallel to the first plane by a first distance which is arranged in an area proximate to the heterojunction and which is larger than a second distance which is arranged in an area distal to the heterojunction.

摘要： A semiconductor component has a semiconductor body in which a trench structure is provided. An electrode structure embedded in the trench structure is at least partly insulated from its surroundings by an insulation structure, and is contact-connected in a contact-connecting region via a contact hole that penetrates through an upper region of the insulation structure. The semiconductor component has at least two trenches running next to one another, at least one of said trenches containing a part of the electrode structure. The trenches are oriented so that at least the regions of the insulation structure which are provided in the upper region of the trenches overlap one another in an overlap region. The contact hole is arranged above the at least two trenches in such a way that at least parts of the overlap region and at least one of the electrode structure parts are contact-connected via the contact hole.
