SAN JOSE -- Keithley Instruments Inc. today announced availability of a single-insertion RF and DC parametric test solution for probing wafers of processed communications and high-speed digital devices.
The S400DC/RF was developed in cooperation with major manufacturers of telecommunications components, said the Cleveland-based company, which began showing the new system at Semicon West here today. The new system is aimed at providing rapid testing of semiconductor devices at frequencies in the GHz range, while still providing DC parametric tests that are often required.
Keithley said many testing operations must currently dedicate extra floor space for separate DC and RF testing and probing systems. The new S400DC/FR reduces cost and floor space, while providing higher measurement accuracy, according to the company.
The S400DC/RF ATE tool incorporates an advanced vector network analyzer (VNA) and DC/RF probe card technology to support "lights out" factory automation, according to Keithley. The VNA, interconnects, probe card adapter, probe card, and calibration substrate are specified and calibrated as a complete system. This helps to eliminate the need for technical personnel to monitor what has often been "finicky rack-and-stack systems," said the company.
The DC/RF probe tester integrates Anritsu Co.'s self-calibrating VNAs and GGB Industries' probe cards. This combination allows the S400DC/RF to provide testing throughput that's an order of magnitude higher than rack-and-stack systems, said Keithley.
Keithley said the S400DC/RF has been designed to provide highly repeatable RF measurements of 2-port/4-terminal power parameters that correlate with results from other RF parametric test systems. The company also said the system's 1-kHz frequency resolution makes it easier to "dial in" the desired frequency than with typical rack-and-stack systems, which usually offer less resolution.
The S400DC/RF is now available with prices starting at less than $160,000 for an upgrade from an existing S400 system, and less than $400,000 for a new S400DC/RF ATE System, depending on features.
