SBS-150 Minority Carrier Lifetime Measuring the growth block is the best way to obtain the final wafer minority carrier lifetime. The SBS-150 bulk silicon minority carrier lifetime analyzer is particularly sensitive to the changes in the minority carrier lifetime in the growth direction of the silicon ingot, and can accurately predict the quality and defect status of the cut silicon wafer.
Simple, flexible scanning tool offers a 2D profile of silicon growth quality. Built for simplicity and safety in production environments, with a sophisticated data analysis package enabling research and development.
Product Overview
Measuring as-grown blocks provides the best indication of final wafer lifetime.The SBS-150 bulk-silicon lifetime analyzer is especially sensitive to lifetime variations in the growth direction of silicon ingots, giving an accurate preview of wafer quality and propagation defects.
It addition, the SBS-150 offers the only lifetime scan with a lifetime measurement range of several orders of magnitude – a feature that is typical of Sinton Instruments true bulk lifetime characterization.
System Capabilities
Primary applications:
Example of lifetime map, taken at a medium resolution. Similar maps of resistivity and trap density are also standard.
