Publication number: 20130032841Abstract: A light-emitting device which has various emission colors and can be manufactured efficiently and easily is provided. A first conductive layer formed of a semi-transmissive and semi-reflective conductive film is provided in a first light-emitting element region, so that the intensity of light in a specific wavelength region is increased with a cavity effect. As a result, the light-emitting device as a whole can emit desired light.

Publication number: 20130032845Abstract: A vertical GaN-based LED is made by growing an epitaxial LED structure on a silicon wafer. A silver layer is added and annealed to withstand >450° C. temperatures. A barrier layer (e.g., Ni/Ti) is provided that is effective for five minutes at >450° C. at preventing bond metal from diffusing into the silver.

After wafer bonding, the silicon is removed, gold-free electrodes (e.g., Al) are added, and the structure is singulated.

Publication number: 20130032885Abstract: Gridded polysilicon semiconductor layouts implement double poly patterning to cut polylines of the layout into polyline segments. Devices are arranged on the polyline segments of a common polyline to reduce the area used to implement a circuit structure relative to conventional gridded polysilicon layout. Stacking of PMOS and NMOS devices is enabled by using double poly patterning to implement additional cuts which form additional polyline segments. Metal layer routing may connect nodes of separate polyline segments.Type: ApplicationFiled: August 3, 2011Publication date: February 7, 2013Applicant: QUALCOMM INCORPORATEDInventors: Chethan Swamynathan, Jay Madhukar Shah, Vijayalakshmi Ranganna, Foua Vang, Pratyush Kamal, Prayag B.

Publication number: 20130032886Abstract: A structure has a semiconductor substrate and an nFET and a pFET disposed upon the substrate. The pFET has a semiconductor SiGe channel region formed upon or within a surface of the semiconductor substrate and a gate dielectric having an oxide layer overlying the channel region and a high-k dielectric layer overlying the oxide layer. A gate electrode overlies the gate dielectric and has a lower metal layer abutting the high-k layer, a scavenging metal layer abutting the lower metal layer, and an upper metal layer abutting the scavenging metal layer. The metal layer scavenges oxygen from the substrate (nFET) and SiGe (pFET) interface with the oxide layer resulting in an effective reduction in Tinv and Vt of the pFET, while scaling Tiny and maintaining Vt for the nFET, resulting in the Vt of the pFET becoming closer to the Vt of a similarly constructed nFET with scaled Tinv values.Type: ApplicationFiled: August 1, 2011Publication date: February 7, 2013Applicant: International Business Machines CorporationInventors: Takashi Ando, Changhwan Choi, Martin M.

Publication number: 20130032890Abstract: CMOS devices (60, 61, 61?) having improved latch-up robustness are provided by including with one or both WELL regions (22, 29) underlying the source-drains (24, 25; 31, 32) and the body contacts (27, 34), one or more further regions (62, 62?, 62-2) doped with deep acceptors or deep donors (or both) of the same conductivity type as the corresponding WELL region and whose ionization substantially increases as operating temperature increases. The increase in conductivity exhibited by these further regions as a result of the increasing ionization of the deep acceptors or donors off-sets, in whole or part, the temperature driven increase in gain of the parasitic NPN and/or PNP bipolar transistors inherent in prior art CMOS structures. By clamping or lowering the gain of the parasitic bipolar transistors, the CMOS devices (60, 61, 61?) are less likely to go into latch-up with increasing operating temperature.Type: ApplicationFiled: August 3, 2011Publication date: February 7, 2013Inventors: Yanxiang Liu, Xiaodong Yang, Gan Wang
