Abstract: A method for forming a semiconductor device includes etching, in a masked etching process, through a layer stack located on a surface of a semiconductor substrate to expose the semiconductor substrate at unmasked regions of the layer stack. The method further includes etching, in a selective etching process, at least a first layer of the layer stack located adjacently to the semiconductor substrate. A second layer of the layer stack is less etched or non-etched compared to the selective etching of the first layer of the layer stack, such that the first layer of the layer stack is laterally etched back between the semiconductor substrate and the second layer of the layer stack. The method further includes growing semiconductor material on regions of the surface of the semiconductor substrate exposed after the selective etching process.

Abstract: To permit formation of a threading element as a closed-loop structure, while being capable of accommodating threading paths of different lengths, the threading element is formed as a sprocket chain which has a long return portion (1) in a return path, coupled to a driven sprocket wheel (2), and connecting portions (3, 4) of a length suitable for the respective threading paths (B, C), and selectively connectable with the return portion (1), to thereby form a closed loop with the selected connecting portion (3 or 4). Pneumatically operated pistons located on path selection switches (5, 6) push the last link of the return portion into engagement with a selected end of the connecting portion, for example by engaging a cross pin (26) in a slotted end link (22, 23; 24, 25) of the connecting portions.
