Intel made a significant breakthrough in the 90nm process generation by introducing strained silicon on both the N and PMOS transistors.NMOS strain was introduced by adding a high-stress layer that wrapped around the transistor (a process sometimes named CESL, or contact etch-stop layer after the most common layer used for …
WebStrained silicon has the potential to greatly increase the mobilities of both electrons and holes, whilst retaining nearly all of the advantages that have allowed silicon to occupy such a dominant position in the semiconductor industry.(12) 1.3 Current Investigation This thesis is an investigation into the properties of strained silicon devices Web11 Dec 2002 · Strained silicon MOSFET technology. Abstract: Mobility and current drive improvements associated with biaxial tensile stress in Si n- and p-MOSFETs are briefly reviewed. Electron mobility enhancements at high channel doping (up to 6 /spl times/ 10/sup 18/ cm/sup -3/) are characterized in strained Si n-MOSFETs.
WebToday, two main integration options remain: gate-first (often referred to as MIPS, metal inserted poly-silicon) and gate-last (also called RMG, replacement metal gate). The … WebStill, today’s strained-silicon technology is under stress. So, chipmakers may need to make a materials change in the channels at 10nm or 7nm. At one time, the leading candidate was germanium (Ge) for PMOS and indium-gallium-arsenide (InGaAs) for NMOS. (Ge has an electron mobility of 3,900cm-square-over-Vs, compared to 1,500cm-square-over-Vs ...
