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.
