Đo lường cấy ghép siêu nông (EXLIE SIMS)
Newest semiconductor chip manufacturing and further scaling down of CMOS devices push the limits of junction depths below the 10nm range, with a profile steepness of 1-2nm per decade. At such scale, the SIMS technique can be used to monitor in-depth distributions of dopants, proving that SIMS profiles can be measured with a depth resolution better than 1nm per decade.
