DLS-1000 Deep Level Transient Spectrometer

DLS-1000 is an improved, high sensitivity system. It is eight times more sensitive than its predecessor, the DLS-83D.

The DLS-1000 offers a fully automatic measurement mode as well as providing 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, capture cross section and concentration distribution. It permits identification of the impurities and is capable of detecting contamination concentrations below 2*108 atoms/cm3.
