Summary on Grant Application Form |
|
It is proposed to grow, fabricate and measure a number of different novel, Si/SiGe electrical devices using the technique of regrowth. Substrates, prepatterned at Cambridge will have epitaxial material regrown on them before devices are fabricated (using CMOS compatible techniques) and measured at Cambridge. Devices to be investigated include short channel (sub 0.1...) vertical MODFET devices where MBE layers define the short channels and expensive high resolution lithography is not required. Double channel devices for both high power (especially mobile communication applications) and ultra high speed will also be pioneered. Regrown material over etched ridges and troughs along with over oxides will be investigated to assess the potential of such materials to be used as low resistivity interconnects. Coupled electron-hole structures with the theoretical possibility of a room temperature superconducting state will be investigated. Since the proposal plans to investigate silicon quantum devices with fabrication techniques compatible with CMOS plants, the success of the project would allow industry to increase performance by changing the architectures in the present fabrication plants for a small increase in cost rather than scaling the present architecture to 0.1... gate lengths which is believed to require fabrication plants costing >10 billion dollars.
