High-sensitivity deep level spectrometer for semiconductor defect characterization, impurity identification, and deep-level transient spectroscopy analysis in wafer and materials applications. The system is based on deep-level transient spectroscopy (DLTS), a characterization platform for studying electrically active defects, also known as charge carrier traps, in semiconductors. It is designed to support advanced contamination analysis and defect investigation in semiconductor materials and structures. DLS-83D allows automatic control of experimental parameters and automatic evaluation of impurity concentration, activation energy, and capture cross section on semiconductor samples. This helps improve analysis efficiency while supporting accurate defect and contamination identification. In CMOS imaging technology, the increasing requirement for the detection of metallic contamination in silicon pushes DLTS techniques toward more sensitive measurements. DLS-83D is built to address this need with high sensitivity, flexible control, and broad measurement capability for advanced semiconductor analysis workflows. Supports very high sensitivity measurement below 10¹ p atoms/cm³ for detection of trace contaminant levels and electrically active defects in semiconductor samples. Automatically evaluates impurity concentration, activation energy, and capture cross section to support efficient and repeatable semiconductor defect analysis. Supports multiple cryostat configurations for different temperature ranges, enabling flexible low-temperature and elevated-temperature semiconductor characterization. Designed for temperature, frequency, electrical, and optical defect analysis workflows across a wide range of semiconductor research and wafer analysis applications. Deep-level transient spectroscopy (DLTS) is the characterization platform for studying electrically active defects, known as charge carrier traps, in semiconductors. It is widely used to identify and analyze deep-level impurities and defect states that affect semiconductor device performance. In CMOS imaging technology, the industry faces a pressing requirement for detection of metallic contamination in silicon. This creates demand for DLTS techniques that can deliver more sensitive measurements and more reliable defect identification for advanced semiconductor process control and materials research. Temperature range from 30 K to 325 K for low-temperature defect characterization and semiconductor trap analysis. Controlled LN flow cryostat with temperature range from 80 K to 550 K / 800 K for broader thermal measurement capability. Temperature range from 80 K to 450 K for practical cryogenic semiconductor defect and impurity analysis workflows. Multiple cryostat configurations help adapt the DLS-83D to different semiconductor materials, defect states, and temperature-dependent characterization requirements. Used for analysis of electrically active defects, charge carrier traps, and contamination effects in semiconductor materials and wafer structures.
