DLS-83D

The DLS-83D offers a fully automatic measurement mode, as well as provides complete interpretation of the measured data, including impurity identification and concentration determination without any need for user interaction.

The Deep Level Transient Spectroscopy (DLTS) is the best technique for monitoring and characterizing deep levels caused by intentionally or unintentionally introduced impurities and defects in semiconductor materials and complete devices. It is an extremely versatile method for determining all parameters associated with deep traps, including energy level, capturing cross-section and concentration distribution. It allows the identification of the impurities, and is capable of detecting contamination concentrations below 109 atoms/cm3.
