Product Overview:
The Keithley 4200-SCS (Semiconductor Characterization System) is an integrated system for I-V characterization of semiconductor devices and materials. Depending on the configuration, the instrument has two standard SMUs (resolution 1pA) and two pre-amplified SMUs (resolution 100fA). When combined with a ground unit (GRNU), this provides the ability to perform up to five end-device measurements. The 4200-SCS is an ideal instrument for performing transistor characterization and parameter measurement. It can also be used for diode characterization. Advanced users can use the instrument's flexible configuration and extremely high sensitivity for other purposes, such as pressure testing and quasi-static C-V measurements.
The 4200-SCS delivers truly outstanding sensitivity and performance through a convenient user interface. However, users are strongly advised to note that successful low current measurements (e.g., below 1pA) require appropriate clamps and proficiency in shielding and protection techniques. Therefore, users are encouraged to take the time to study the equipment operating manual and carefully consider their sample configuration and experimental conditions. Failure to make this commitment will result in compromised equipment performance and less than optimal results. An important consideration in all test configurations is the trade-off between test sensitivity and test time. Very low current testing is limited by the laws of physics (shot noise), and accuracy is achieved through a long test (integration) time.
Input to the instrument is provided via a low noise triaxial cable. To maximize performance, the test fixture should be configured as close as possible to the protected connection of the device under test (DUT).
MTW engineers can provide advice and assistance with DUT fixtures and programming of the device under test through the GUI. Users who wish to take advantage of the instrument's features without a full understanding of its operation should anticipate the need for purchase assistance.
This instrument is an excellent choice for users who require the highest sensitivity within the available operating range.
