摘要:
A method for fabricating a plurality of semiconductor bodies, in particular based on nitride compound semiconductor material. The method includes forming a mask layer (3) over a substrate (1) or over an initial layer (2), which mask layer has a plurality of windows (4) leading to the substrate (1) or to the initial layer (2), etching back the substrate (1) or the initial layer (2) in the windows (4), in such a manner that pits (41) are formed in the substrate (1) or in the initial layer (2) starting from these windows. The semiconductor material (5) is grown onto the substrate (1) or onto the initial layer (2), in such a manner that lateral growth is promoted and the semiconductor material initially grows primarily from the flanks (43) of the pits (41) toward the center (42) of the pits (41) where they form a coalescence region (61), so that defects in the substrate (1) or in the initial layer (2) which impinge on the flanks (43) of the pits (41) bend off toward the center of the pits (41) in the semiconductor material, and then, starting from the windows (4), the semiconductor material grows over the mask layer (3) and grows together over the mask layer (3) between adjacent windows (4), where it forms a further coalescence region (62). A component layer sequence (8) is grown onto the semiconductor material (5).

摘要:
The invention relates to a press furnace for a denture or partial denture, having a combustion chamber in which a press mold, in particular a muffle, having a press channel for the introduction of a ram can be positioned, and a drive for driving the ram, wherein, in order to improve the drive of the press furnace, the drive provided is an electromagnet, the magnetic armature or magnetic coil of which drives the ram.
摘要:
An optoelectronic module for emitting monochromatic radiation in the visible wavelength range is specified. The module has a plurality of light emitting diode chips which generate UV radiation. The UV radiation is converted into light in the visible range, for example, into green light, by a wavelength converter. The coupling-out of light from the module is optimized by the use of two selectively reflecting and transmitting filters. This module can be used as a light source in a projection apparatus.
