A method of implanting an implant species into a substrate at different depths is described. The method includes forming an implant mask over the substrate. The implant mask includes a first implant zone designed as an opening and a second implant zone designed as a block array. The implant species is implanted through the implant mask under an implant angle tilted against a block plane, such that a first implant area is formed by the implant species at a first depth in the substrate beneath the first implant zone and a second implant area is formed by the implant species at a second depth in the substrate beneath the second implant zone. The first depth is greater than the second depth.

Method of implanting an implant species into a substrate at different depths

Various embodiments provide a method for processing a carrier, the method including changing the three-dimensional structure of a mask layer arranged over the carrier so that at least two mask layer regions are formed having different mask layer thicknesses; and applying an ion implantation process to the at least two mask layer regions to form at least two implanted regions in the carrier having different implantation depth profiles.

A method for forming a semiconductor device includes providing a semiconductor substrate having an upper side and comprising, in a vertical cross-section substantially orthogonal to the upper side, a plurality of semiconductor mesas of a first monocrystalline semiconductor material which are spaced apart from each other by sacrificial layers selectively etchable with respect to the first monocrystalline semiconductor material and arranged in trenches extending from the upper side into the semiconductor substrate, forming on the semiconductor mesas a support structure mechanically connecting the semiconductor mesas, at least partly replacing the sacrificial layers while the semiconductor mesas remain mechanically connected via the support structure, and at least partly removing the support structure.

Methods for manufacturing semiconductor devices

A method for producing a semiconductor device is provided. The method includes: forming in a semiconductor substrate a plurality of semiconductor mesas extending to an upper side so that adjacent semiconductor mesas are spaced apart from each other by one of a substantially empty trench and a trench substantially filled with a sacrificial layer selectively etchable with respect to the semiconductor mesas; forming a support structure mechanically connecting the semiconductor mesas spaced apart from each other by one of the substantially empty trench and the trench substantially filled with the sacrificial layer; and processing the semiconductor substrate from the upper side while the semiconductor mesas are mechanically connected via the support structure.
