Intel And IQE Will Speed Up Transistors With InGaAs
The firms recently presented work at the IEDM 2010 Conference in San Francisco regarding how InGaAs FETs could be used for low power logic applications.
Intel and IQE recently presented a joint paper on the development of InGaAs Quantum Well Field Effect Transistors (QWFETs) for low power logic applications.
The paper was presented by Marko Radosavljevic from Intel at the International Electron Devices Meeting (IEDM) held in San Francisco. The paper detailed work carried out by scientists at Intel’s Technology and Manufacturing Group in Oregon and IQE’s epitaxial growth facility in Bethlehem, Pennsylvania.
The paper entitled, “Non-Planar, Multi-Gate InGaAs Quantum Well Field Effect Transistors with High-K Gate Dielectric and Ultra-Scaled Gate-to-Drain/Gate-to-Source Separation for Low Power Logic Applications," reports results of work on InGaAs QWFETs with high-K gate dielectric and ultra-scaled gate-to-drain and gate-to-source separations (LSIDE) of 5nm.
The QWFET devices fabricated by Intel using epitaxial wafers produced by IQE, show improved enhancement-mode threshold voltage (VT) and significantly improved electrostatics. The results of this work demonstrated that non-planar, multi-gate device architecture are an effective way to improve the scalability of III-V QWFETs for low power logic applications.
The IEDM has for almost sixty years been the world's main forum for reporting breakthroughs in technology, design, manufacturing, physics and the modeling of semiconductors and other electronic devices. Proceedings of the conference will be published by the IEEE.
IQE is a global supplier of advanced semiconductor wafers with products that cover a diverse range of applications, supported by an innovative outsourced foundry services portfolio that allows the Group to provide a 'one stop shop' for the wafer needs of the world's leading semiconductor manufacturers.
IQE uses different forms of epitaxy to supply bespoke semiconductor wafers to major chip manufacturing companies, who then use these wafers to make the chips which form the key components of virtually all high technology systems. These include HBTs for mobile phones, VCSELs for remote controls as well as solar cells. IQE supplies wafers using all of the leading crystal growth technology platforms.
The firm has eight operating facilities, two located in Cardiff, Wales, and another two in the South of England based in Milton Keynes and Bath. IQE also has facilities in Bethlehem, Pennsylvania, Somerset, New Jersey and Spokane, Washington based, in the USA and in Singapore.
