Research and Teaching Interests
The processing of semiconductors for the microelectronic industry remains an example of a discipline for which technology is leading science. There is a growing demand by the industry for processes which can yield components which are smaller, more densely packed and capable of greater electronic speed. The critical processes which limit development in this area are fine line anisotropic etching and the passivation of surfaces and interfaces. In response to these needs several processes which could be important to future developments in this technology are being studied. These include:
(a) the laser enhanced etching of gallium arsenide and silicon with chlorine, bromine and iodine molecules and atoms. These are seen as possible anisotropic etching techniques which avoid the component damage which is characteristic of current plasma-based techniques.
(b) the oxidation of silicon by atomic oxygen to form "gate oxides".
(c) the use of photoluminescence to monitor the passivation of III-V semiconductor surfaces and interfaces, and laser induced photconductivity to monitor the passivation level of silicon/silica interfaces.
(d) the processing and characterization of SiGex thin films for high-speed MOSFETs.
