摘要: A first semiconductor zone of a first conduction type is formed from a semiconductor base material doped with first and second dopants. The first and second dopants are different substances and also different from the semiconductor base material. The first dopant is electrically active and causes a doping of the first conduction type in the semiconductor base material, and causes either a decrease or an increase of a lattice constant of the pure, undoped first semiconductor zone. The second dopant may be electrically active, and may be of the same doping type as the first dopant, causes one or both of: a hardening of the first semiconductor zone; an increase of the lattice constant of the pure, undoped first semiconductor zone if the first dopant causes a decrease, and a decrease of the lattice constant of the pure, undoped first semiconductor zone if the first dopant causes an increase, respectively.

摘要: A method of fabricating a semiconductor chip includes the providing an adhesive layer on the outer area of the active surface of a device wafer and attaching a rigid body to the active surface by the adhesive layer. The device wafer is thinned by treating the passive surface of the device wafer. A first backing tape is connected to the passive surface of the device wafer. The outer portion of the rigid body is separated from the central portion of the rigid body and the outer portion of the device wafer is separated from the central portion of the device wafer. The central portion of the rigid body, the outer portion of the device wafer and the outer portion of the rigid body are removed from the first backing tape. The device wafer may be diced into semiconductor chips.

摘要: The invention relates to a vertical arrangement of at least two semiconductor components which are electrically insulated from one another by at least one passivation layer. The invention likewise relates to a method for fabricating such a semiconductor arrangement. A semiconductor arrangement is specified in which, inter alia, the risk of cracking at the metallization edges, for example, caused by thermomechanical loading, is reduced and the fabrication-dictated high content of radical hydrogen is minimized. Furthermore, a method for fabricating such a semiconductor arrangement is specified.
