High Throughput Wafer Production Test

22 September 2011 - Keithley Instruments has introduced an upgrade to its popular Keithley Test Environment (KTE) semiconductor test software. KTE Version 5.3 is designed for use with Keithley's S530 Parametric Test Systems, the company's fastest, most cost-effective line of process control monitoring solutions to date.

KTE is a powerful test development and execution software platform that has served hundreds of semiconductor fabs worldwide with Keithley's previous-generation parametric test systems. Now, Keithley's S530 test systems can leverage the same industry-proven software platform, providing flexible test plan development and high speed test execution for even the most demanding production environments. Users of existing Keithley S400 and S600 Series parametric testers especially benefit from KTE Version 5.3 on the S530 because existing measurement routines can easily be ported to the S530, and identical test plans can be shared between existing testers and new S530 systems.

For customers already using earlier versions of KTE, KTE V5.3 speeds and simplifies integrating S530 test systems into their test floors:

The same test recipes and test plans can be used for all Keithley automated parametric test systems, which not only shortens the learning curve for test engineers and operators working with multiple systems but offers a smooth migration path to protect the fab's test development investment when adding new high speed systems to the test floor or replacing older ones.

Users can continue working with the familiar user libraries they've developed for earlier Keithley systems over the years after recompiling and rebuilding them for use with the S530. Typically, only minimal debugging is required.

KTE V5.3 simplifies creating new user access point (UAP) source code for conditional test sequencing and customizing the flow of the S530's system operation. UAP source code developed for earlier Keithley systems is applicable to S530 systems with minimal adjustments.

The tools within KTE provide identical functionality for all Keithley parametric test platforms.

KTE for the S530 is designed to run on a Linux operating system on a standard industrial PC to ensure long-term stability and ease of maintenance. The software has been optimized for speed and extended reliability in high throughput production test environments. S530 systems running KTE V5.3 can address all the DC I-V and C-V measurements required in process control monitoring, process reliability monitoring, and device characterization. They are optimized for use in production parametric test environments that must accommodate a broad mix of products or wherever wide application flexibility and fast test plan development are critical.
