Description

DLS-1100 Deep Level Transient Spectrometer

The DLS-1100 Deep Level Transient Spectrometer is a premier metrology platform designed for characterizing electrically active defects and lattice impurities in semiconductor materials. Integrating low-vibration cryostat technology with advanced signal processing, it enables automated measurement of trap concentration, activation energy, and capture cross-sections. Engineered for wafer manufacturers and research institutes, the DLS-1100 provides critical data to ensure optimal carrier performance and material purity.

Product Overview

Deep Level Transient Spectroscopy (DLTS) is essential for identifying traps that limit device efficiency. The DLS-1100 supports comprehensive measurement modes including temperature scans, frequency scans, and depth profiling. With high-speed digitization of capacitance transients, it provides detailed numerical evaluations via a specialized Transient Recorder.

The system is built for versatility, accommodating both standard Capacitance DLTS and Current-based DLS (I-DLS) for conductive samples. Improved evaluation software automates experimental control, allowing precise characterization of impurity levels across a wide thermal range.
