  • Patent number: 8592262
    Abstract: A method is used to prevent unwanted electrical contacts between various electrically conducting surfaces and lines in a display panel due to an n+ a-Si residue and/or ITO debris. The method provides a clearing pattern including at least a cleared area in the passivation layer for preventing the residue or debris from locating at the cleared area. As such, if an n+ a-Si residue happens to be deposited under the passivation layer, the part of the residue located in the cleared area is removed by an a-Si selective etching process, for example. Furthermore, with the cleared area, ITO debris deposited on the section of the dielectric layer deposited on the signal line can be electrically isolated from the electrode.

  • Patent number: 8574970
    Abstract: A MOSFET device is formed on top of a semiconductor-on-insulator (SOI) substrate having a semiconductor layer with a thickness ranging from 3 nm to 20 nm. A stair-shape raised extension, a raised source region and a raised drain region (S/D) are formed on top of the SOI substrate. The thinner raised extension region abuts at a thin gate sidewall spacer, lowering the extension resistance without significantly increasing the parasitic resistance. A single epitaxial growth forms the thinner raised extension and the thicker raised S/D preferably simultaneously, reducing the fabrication cost as well as the contact resistance between the raised S/D and the extension. A method of forming the aforementioned MOSFET device is also provided.
