摘要:
A plurality of light-emitting diode light sources of the same kind are produced simultaneously. Each light source includes a light-emitting diode chip and a luminescence conversion element, which converts the wavelength of at least part of an electromagnetic radiation emitted by the light-emitting diode chip. In a first process, a layer composite with a light-emitting diode layer sequence applied to a carrier substrate is provided. The wafer is provided with trenches and then inserted into a cavity of a mold. A molding compound, which contains a luminescence conversion material, is driven in, so that the trenches are at least partly filled with the molding compound. The mold is then removed and the light-emitting diode light sources are separated from the layer composite. In a second process, instead of the layer composite, a plurality of light-emitting diode chips which are applied to a common carrier in a regular arrangement are provided.
摘要:
A housing accommodating a semiconductor chip is set out. The housing and chip may be used for sending and/or receiving radiation. Popular applications of the housing may be in light emitting diodes. The housing includes a conductor strip that is punched into two electrically isolated portions. The housing further includes a cavity extending inwards from the top of the housing. The conductor portions include respective areas that are exposed at the bottom of the cavity. The semiconductor chip is bonded to one of the exposed areas and a wire bonds the chip to the second exposed area. The conductor portions also terminate in exposed electrodes, which allow for electrical connection of the chip with external devices. A window is formed in the cavity and the walls of the housing that form the cavity may be made of a reflective material. The electrodes remain unexposed to the window but for any residual areas about the chip and bonding wire within the first and second exposed areas. By minimizing the area of the conductor exposed to the window, delamination brought about by the different thermal expansions of the window and conductor are minimized and/or eliminated. Likewise, with a reflective housing covering the base of the cavity that accommodates the window, internal radiation reflection is increased over that which was achieved with an exposed conductor.

摘要:
In a two-pole SMT miniature housing in leadframe technique for semiconductor components, a semiconductor chip is mounted on one leadframe part and is contacted to a further leadframe part. The further leadframe part is conducted out of the housing in which the chip is encapsulated as a solder terminal. No trimming or shaping process is required and the housing is tight and is capable of further miniaturization. The solder terminals as punched parts of the leadframe are conducted projecting laterally from the housing sidewalls residing opposite one another at least up to the housing floor which forms the components' mounting surface. The chip mounting surface and the components' mounting surface form a right angle with one another.
