Summary on Grant Application Form |

This proposal is for a collaborative programme of research to develop SiGe HBT technology for mobile communication applications up to and beyond 5.5ghz. High speed and low power consumption will be achieved by producing SiGe HBTs on wafer bonded SOI substrates incorporating buried silicide layers. Experimental work will include studies of process uniformity, defect control and yield for different device architectures and SiGe growth methods, including selective and non-selective LPCVD SiGe growth and gas source MBE. Theoretical work will include the devising of improved circuit models for SiGe HBTs on Si and SOI substrates, which incorporate mechanisms such as neutral base recombination and self-heating in Si islands. In addition, mixed mode circuit simulations will be performed to investigate how the overall device and process design can be optimised to give minimum power consumption consistent with circuit operation at 5.5ghz and beyond. Fundamental scientific issues addressed by the project will include the introduction of carbon into SiGe to suppress transient enhanced diffusion (TED), investigations of novel process architectures which avoid direct implantation into SiGe and hence avoid TED and investigations of the effectiveness of buried silicides for heat removal from SOI islands.
