A detailed 2D process simulation of strained silicon PMOS (SSPMos) and its electrical characterization was done using TCAD tool. With the oxide thickness, Tox of 16 nm and germanium concentration of 35%, the threshold voltage Vt for the strained Si and conventional PMOS is -0.5067V and -0.9290V respectively. This indicates that the strained silicon had lower power consumption. Beside that, the drain induced barrier lowering (DIBL) value for the strained PMOS is 0.3034V and the conventional PMOS is 0.4747V, which shows a better performance for strained silicon as compared to conventional PMOS. In addition, the output characteristics were also obtained for SSPMos which showed an improvement of drain current compared with conventional PMOS.","PeriodicalId":136703,"journal":{"name":"2006 IEEE International Conference on Semiconductor Electronics","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2006-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131827849","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It's been reported in [1] that a 67 GHz f<sub>max</sub> novel lateral BJT's on TFSOI has been fabricated with a simplified process. This paper presents an investigation of this high performance transistor by using 2D process and device numerical simulation. Accurate geometrical structure and reasonably good doping profiles with a simple fabrication process are successfully achieved in the process simulation. However, a careful attention is required to define the mesh for the device to obtain an accurate measurement of device characteristics. With a base, low-doped collector, emitter and high-doped collector concentrations of 3 times 10<sup>17</sup> cm<sup>-3</sup>, 1.0 times 10<sup>17</sup> cm<sup>-3</sup>, 5 times 10<sup>20</sup> cm<sup>-3</sup> and 3 times 10<sup>20</sup> cm<sup>-3</sup> respectively, a variation of 0.1-0.13 mum base width is observed. I-V and frequency performance of these transistors are simulated and analyzed.

Attention is focused on the Ga- rich composition samples (0 les x < 0.10). The Al-mole fraction is determined by high- resolution X-ray diffraction (HR-XRD) spectroscopy. Ultraviolet-visible (UV-VIS) transmission and micro-photoluminescence (mu-PL) spectroscopy are employed to determine the energy band gap of the samples. The XRD results revealed that the Bragg angle of the rocking curve (RC) peak gradually increases as the Al-mole fraction increases, indicating the reductions in the lattice constant c of the alloys. By the application of Vegard's law, the Al-mole fractions of AlxGa1-xN samples have been calculated. Overall, the UV-VIS transmission and mu-PL results showed that as the Al-mole fraction increases, blue shifts of the absorption edge and band edge emission are observed in all samples. These indicate the strong dependence of the band gap energy of AlxGa1-xN on the Al-mole fraction. Finally, the band gap energy of the AlxGa1-xN as a function of Al-mole fraction have been plotted and the energy band gap bowing parameter of 14.62 eV is obtained from the best fit of the non-linear interpolation of the UV-VIS transmission and the PL data.","PeriodicalId":136703,"journal":{"name":"2006 IEEE International Conference on Semiconductor Electronics","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2006-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129523494","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
