  • Patent number: 6864112
    Abstract: The present invention relates to a method for the production of semiconductor components. This method comprises the steps of applying masking layers and components on epitaxial semiconductor substrates within the epitaxy reactor without removal of the substrate from the reactor. The masking layers may be HF soluble such that a gas etchant may be introduced within the reactor so as to etch a select number and portion of masking layers. This method may be used for production of lateral integrated components on a substrate wherein the components may be of the same or different type. Such types include electronic and optoelectronic components. Numerous masking layers may be applied, each defining particular windows intended to receive each of the various components. In the reactor, the masks may be selectively removed, then the components grown in the newly exposed windows.

  • Patent number: 6812500
    Abstract: The light-radiating semiconductor component has a radiation-emitting semiconductor body and a luminescence conversion element. The semiconductor body emits radiation in the ultraviolet, blue and/or green spectral region and the luminescence conversion element converts a portion of the radiation into radiation of a longer wavelength. This makes it possible to produce light-emitting diodes which radiate polychromatic light, in particular white light, with only a single light-emitting semiconductor body. A particularly preferred luminescence conversion dye is YAG:Ce.

  • Publication number: 20040202819
    Abstract: A substrate with banks having end channels is provided to advantageously allow excess fluid collecting on one part of the substrate to flow to another part of the substrate. An excess of fluid collecting in a particular area of the substrate may flow to an area of the substrate where it would not interfere with the manufacturing process. The end channels may be modified with wave breakers that act as buffers to redirect excess fluid and/or with capillary-force homogeneity enhancers that pull excess fluid away from other parts of the substrate. The end channels may also contain line-end reservoirs that provide additional room for excess fluid to collect.

  • Patent number: 6797211
    Abstract: A method of fabricating a device, including mechanically patterning a device layer using a stamp containing a desired pattern. The device layer is formed on a plastic or polymeric substrate. The stamp is pressed against the substrate under a load which patterns the device layer without cracking the device layer in the non-patterned areas.

  • Patent number: 6797940
    Abstract: The present invention relates to an optical encoder for measuring the speed and direction of a moving raster. The raster may be moving linearly or angularly and may further be connected to a moving element, such as a spinning shaft, of which speed and orientation measurement Is sought. The raster may comprise a slit plate or the like and include many formations in sequence. The formations may be successively opaque and transparent to light. The raster modulates light from a light source and the modulated light is detected by at least one set of three photodetectors. Output of the photodetectors is then used to generate a reference signal to which individual outputs are compared. The results of the comparisons are indicative of the speed and direction of the raster and moving element to which the raster is attached.

  • Patent number: 6713795
    Abstract: An ultraviolet light radiation photodetector includes a quartz lens, a UV transmission filter, a silicon photodiode, and a scintillator layer. After passing through the quartz lens and the UV transmission filter, the UV light to be detected is converted in the scintillator layer, preferably applied to the surface on a light-exiting side of the UV transmission filter, into light radiation of a greater wavelength, for which the silicon photodiode exhibits a greater sensitivity. If desired, an additional edge filter can be used to improve the configuration's drop in sensitivity between 350 and 400 nm.
