  • Publication number: 20250042146
    Abstract: A method for fabricating blanks for light-guide optical elements from a compound glass stack is disclosed. The compound glass stack is aligned to the cutting planes so that light reflecting layers arranged between the glass plates bonded together making up the compound glass stack have a defined orientation with respect to the side faces of the slices after cutting. The compound glass stack has a plane with a defined orientation, so that the light reflecting layers within the slices are correctly oriented when the cutting planes run parallel to the plane of the compound glass stack. The alignment of the compound glass stack to the cutting planes includes adjusting the tilt angles of the plane of the compound glass stack with respect to the cutting planes using an autocollimator, and adjusting the position of the compound glass stack in a direction obliquely to the cutting planes.

  • Patent number: 11984392
    Abstract: A semiconductor package includes: a carrier having an electrically insulative body and a first contact structure at a first side of the electrically insulative body; and a semiconductor die having a first pad attached to the first contact structure of the carrier, the first pad being at source or emitter potential. The first pad is spaced inward from an edge of the semiconductor die by a first distance. The semiconductor die has an edge termination region between the edge and the first pad. The first contact structure of the carrier is spaced inward from the edge of the semiconductor die by a second distance greater than the first distance such that an electric field that emanates from the edge termination region in a direction of the carrier during normal operation of the semiconductor die does not reach the first contact structure of the carrier. Methods of production are also provided.
