Abstract
A method of aligning semiconductor chips in a medium includes providing an electrically insulating liquid medium; providing semiconductor chips; forming a suspension with the medium and the semiconductor chips; exposing the semiconductor chips to electromagnetic radiation that generates free charge carriers in the semiconductor chips; arranging the suspension in an electric field in which the semiconductor chips are aligned along the electric field; and curing the medium after aligning the semiconductor chips.
