  • Patent number: 11935941
    Abstract: A semiconductor structure includes a substrate, a conductive region, a first insulation layer, a second insulation layer, a gate structure, a low-k spacer, a gate contact, and a conductive region contact. The low-k spacer is formed between a sidewall of the gate structure and the first insulation layer. The gate contact is landed on a top surface of the gate structure. A proximity distance between a sidewall of the gate contact and the conductive region contact along a top surface of the second insulation layer is in a range of from about 4 nm to about 7 nm. A method for manufacturing a semiconductor structure is also provided.

  • Publication number: 20240087961
    Abstract: The embodiments described herein are directed to a method for reducing fin oxidation during the formation of fin isolation regions. The method includes providing a semiconductor substrate with an n-doped region and a p-doped region formed on a top portion of the semiconductor substrate; epitaxially growing a first layer on the p-doped region; epitaxially growing a second layer different from the first layer on the n-doped region; epitaxially growing a third layer on top surfaces of the first and second layers, where the third layer is thinner than the first and second layers. The method further includes etching the first, second, and third layers to form fin structures on the semiconductor substrate and forming an isolation region between the fin structures.

  • Publication number: 20120147386
    Abstract: A touch device with light frequency sensor to sense the relative position of an object to be detected includes a work area, a light source, at least two light frequency sensors, and a position computation module. The light source is arranged toward the work area for providing light with predetermined frequency. The two light frequency sensors are arranged for respectively detecting the light frequency signals entered into the lens and the optical filter. The position computation module is linked with the two light frequency sensors for signal connection and detects characteristic data by means of trigonometry to determine the position of the object to be detected. As the light frequency sensor could simple detects the signal, the position computing module with a relative low-order computing is capable of processing the signal. That means the high-order processor of the prior art is unnecessary to be used to processing the acquired image.

  • Publication number: 20110273385
    Abstract: A sensing structure and method for a touch spot of a resistive touch panel, includes a first conducting layer, with a frame of the first conducting layer defined as an X-axis, a plurality of parallel first resistance detecting lines designed towards Y-axis; and a second conducting layer coincident with the first conductive layer, and a plurality of second resistance detecting lines with certain slope angles on the second conducting layer. The plural second resistance detecting lines intersect plural first resistance detecting lines to form interlacing and fixed blocks. In response to a screen touch, the position of the Y-axis of the second resistance detecting line is used in a triangulation calculation.
