  • Patent number: 8796053
    Abstract: Photolithographic methods of forming a roughened surface for an LED to improve LED light emission efficiency are disclosed. The methods include photolithographically imaging a phase-shift mask pattern onto a photoresist layer of a substrate to form therein a periodic array of photoresist features. The roughened substrate surface is created by processing the exposed photoresist layer to form a periodic array of substrate posts in the substrate surface. A p-n junction multilayer structure is then formed atop the roughened substrate surface to form the LED. The periodic array of substrate posts serve as scatter sites that improve the LED light emission efficiency as compared to the LED having no roughened substrate surface. The use of the phase-shift mask enables the use of affordable photolithographic imaging at a depth of focus suitable for non-flat LED substrates while also providing the needed resolution to form the substrate posts.

  • Patent number: 8779527
    Abstract: A method and circuit in which the drive strength of a FinFET transistor can be selectively modified, and in particular can be selectively reduced, by omitting the LDD extension formation in the source and/or in the drain of the FinFET. One application of this approach is to enable differentiation of the drive strengths of transistors in an integrated circuit by applying the technique to some, but not all, of the transistors in the integrated circuit. In particular in a SRAM cell formed from FinFET transistors the application of the technique to the pass-gate transistors, which leads to a reduction of the drive strength of the pass-gate transistors relative to the drive strength of the pull-up and pull-down transistors, results in improved SRAM cell performance.

  • Patent number: 8772769
    Abstract: To provide a miniaturized transistor having favorable electric characteristics. An oxide semiconductor layer is formed to cover a source electrode layer and a drain electrode layer, and then regions of the oxide semiconductor layer which overlap with the source electrode layer and the drain electrode layer are removed by polishing. Precise processing can be performed accurately because an etching step using a resist mask is not performed in the step of removing the regions of the oxide semiconductor layer overlapping with the source electrode layer and the drain electrode layer. Further, a sidewall layer having conductivity is provided on a side surface of a gate electrode layer in a channel length direction; thus, the sidewall layer having conductivity overlaps with the source electrode layer or the drain electrode layer with a gate insulating layer provided therebetween, and a transistor substantially including an Lov region is provided.
