Abstract
The invention describes a radiation-emmitting semiconductor component with luminescence conversion element (7), in the case of which the semiconductor body (3) is arranged in a recess in the basic body (1). Within the recess, there is shaped around the semiconductor body a bowl-like region which contains the luminescence conversion element (7) and envelopes the semiconductor body (3). The bowl-like region is formed as a depression within the recess or as an annular enclosure (6) on the base of the recess.
Claims5
A method for producing a radiation emitting semiconductor component with a luminescent conversion element, comprising the steps of:
- forming a base body having a open interior recess and an imbedded conductor frame,
- coating the conductor frame with a compound,
- forming a chip service area on the conductor frame and recessing the area,
- forming a cup like portion on the area, the cup like portion defining an internal recess,
- installing a semiconductor body on the area and bonding the semiconductor body,
- filling the cup like portion with a luminescent conversion element such that a boundary surface of the luminescent conversion element separates the cup like portion internal recess from the open interior recess.
A method for the production of a radiation emitting semiconductor component with a luminescent conversion element, further comprising the steps of:
- forming a base body having an open internal region and an imbedded conductor frame, the frame further comprising a chip service area,
- molding an annular border around the chip service area, the border defining a cup-like portion having an interior area,
- installing a semiconductor body on the chip service area and bonding the semiconductor body, and
- filling the interior area with a luminescent conversion element.
