  • 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.

  • Patent number: 9965098
    Abstract: The present disclosure provides a clamshell electronic device. The clamshell electronic device includes a touch module, a sensing device and a calculation unit. The touch module is arranged to detect touch events. The sensing device is arranged to detect whether an upper cover and a lower cover of the clamshell electronic device are separated, and produce a detecting signal when the upper cover and the lower cover are separated. The calculation unit is arranged to count the number of times the upper cover and the lower cover are separated according to the detecting signal to obtain a separated number, and calibrate the touch module when a predetermined condition is satisfied, wherein the predetermined condition comprises that the separated number is greater than a predetermined number.

  • Patent number: 9266207
    Abstract: The present invention relates to an oblique-driven platform having three coplanar driving axes, in which three oblique driving modules are disposed on an identical base, so as to drive a work platform to rotate and carry out 2-dimensional motion by the controlling of the three oblique driving modules. Thus, this design could solve the problems occurring in the conventional stacked machine tools; such as the deformation or the displacement of the sever axis or the rotation axis caused by the upper-layer machine tools. Moreover, by the disposing of the three oblique driving modules, the work platform can be driven to stably rotate and carry out 2-dimensional motion with high precision and high accuracy.
