    Abstract: An alignment mark definer is configured to provide a geometrical definition for an actual alignment structure to be formed at a temporary surface of a substrate based on a desired appearance of the alignment mark and on an expected alteration of an appearance of the actual alignment structure caused by a deposition material deposited on the temporary surface and the actual alignment structure.

    Abstract: A semiconductor substrate includes a semiconductor base substrate. An alignment structure is formed on a surface of the semiconductor base substrate. An epitaxial layer is deposited on the surface of the semiconductor base substrate. The alignment structure includes an area of the surface of the semiconductor base substrate that is formed as a groove pattern. Grooves of the groove pattern are aligned with a specific crystallographic direction of the semiconductor base substrate. The specific crystallographic direction provides for a slower epitaxial growth rate on such a groove-patterned base substrate surface area compared to epitaxial growth on a surface of the semiconductor base substrate adjacent to the groove-patterned area.

    Abstract: A method for use in manufacturing semiconductor devices includes providing a structured layer on a wafer, and selectively providing a substance on a selected portion of the structured layer. A die comprises a semiconductor device on a substrate, where the semiconductor device includes a substance, and where the substance has a sidewall that is sheer with respect to one or more of a base surface or a top surface of the substrate.
