Abstract
A light-emitting semiconductor component having: a semiconductor element containing an active layer, electrical contacts for impressing a current into the active layer (heat being generated at the active layer and at the electrical contacts during operation), and a carrier with a large thermal capacity for absorbing the heat generated during operation. The rear side of the semiconductor element is electrically and thermally connected to the carrier by a conductive adhesive. Recesses, which accommodate a part of the conductive adhesive when the semiconductor element is connected to the carrier, are provided in the rear side of the semiconductor element.
Claims28
A light-emitting semiconductor component, comprising:
- a semiconductor element including an active layered structure;
- electrical contacts for impressing a current into said active layered structure;
- a carrier for said semiconductor element, said carrier acting as a heat sink;
- and
- a conductive adhesive electrically and thermally connecting said carrier to said semiconductor element;
- said semiconductor element having a side facing said carrier;
- and
- said side formed with a plurality of recesses for accommodating a portion of said conductive adhesive between said semiconductor element and said carrier.
