  • Patent number: 11626371
    Abstract: One or more semiconductor structures and/or methods for forming support structures for semiconductor structures are provided. A first porosification layer is formed over a semiconductor substrate. A first epitaxial layer is formed over the first porosification layer. A second porosification layer is formed from a first portion of the first epitaxial layer and a support structure is formed from a second portion of the first epitaxial layer.
    Type: Grant

  • Patent number: 9698247
    Abstract: A semiconductor arrangement is produced by providing a semiconductor carrier of a second conduction type and epitaxially growing a first semiconductor zone of a first conduction type on the carrier. The first semiconductor zone includes a semiconductor base material doped with first and second dopants which are made of different substances which are both 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 a decrease or an increase of a lattice constant of the first semiconductor zone. The second dopant causes one or both of hardening of the first semiconductor zone and an increase of the lattice constant of the first semiconductor zone if the first dopant causes a decrease, or a decrease of the lattice constant of the first semiconductor zone if the first dopant causes an increase.

  • Patent number: 9306010
    Abstract: 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.

  • Patent number: 6266587
    Abstract: The invention relates to a method for determining engine oil servicing dates for a motor vehicle engine as a function of recorded engine operating parameters. According to the invention, the number of engine revolutions and at least one engine other operating parameter relevant to engine oil ageing are continuously recorded and, on the basis of this, a fictitious distance is determined by associating the recorded engine revolutions with the evaluation factors dependent on recorded engine operating parameter(s) relevant to engine oil ageing in accordance with a predeterminable association relationship. From this, a remaining operating distance until the next engine oil servicing date is then calculated by subtracting the determined fictitious distance from a specified total distance potential.
