With over 40+ years of experience EAG knows SIMS, whether you call it dynamic, static, TOF otherwise. Dynamic SIMS analyses involve dopant and impurity depth profiling, thin film characterization, ultra-high depth resolution, bulk analyses, and high-precision matching of process tools. WebThe early‐stage spectrometer is operated in a mode of dynamic SIMS (DSIMS). The DSIMS directs a high flux of primary ion to the sample surface, eroding the surface rapidly. Therefore, DSISM is not suitable for ultra‐thin surface analysis. A static SIMS (SSIMS) was developed in 1970’s. greatfishing4u.com
