Following our previous study on the material-quality limiting factors of evaporated solid-phase crystallized (SPC) poly-Si thin films fabricated on planar glass for photovoltaic applications, we extend our study to investigate the impurity levels, optical properties, transport properties, and device performance of so-called ??EVA?? (EVAporated Si) solar cells. These potentially cost-effective cells...
A non-classical device structure namely self-aligned quasi-silicon-on-insulator (SOI) metal-oxide semiconductor (MOS) field-effect transistor with pi-shaped semiconductor conductive layer (SA-piFET) is presented, seeking to improve the performance and upgrade the reliability of the SOI-based devices. Designed to equip with a SA single crystal silicon channel layer, plus a natural source/drain (S/D)...
Plasma-exposed Si surface related to Si recess in source/drain region was investigated in detail for various superposed bias configurations with frequencies of 13.56 MHz and 400 kHz. Two different bias powers were utilized by an inductively coupled plasma reactor (ICP). The surface layer (SL) and the interfacial layer between the SL and Si substrate (IL) were analyzed by spectroscopic ellipsometry...
This paper shows that dc device performance and reliability characteristics of CMOSFETs do not have the same dependence on the film stress of contact etch stopping layers (CESLs) in strained silicon technology. Two kinds of CESLs, namely, plasma-enhanced chemical vapor deposition (PE-CVD) SiN and low-pressure CVD SiON, with tensile and compressive stresses, respectively, were used to induce channel...
