LTX-Credence
ASL 3000
The LTX / Credence ASL 3000 is a semiconductor tester. The LTX / Credence ASL 3000's computer configuration includes a Pentium 4 processor, 1GB RAM, 80GB HDD, and Windows NT 4.0 operating system.[1]
What it is
How it works
General reference — not yet source-verifiedA semiconductor test system applies electrical stimuli to a device and measures the resulting responses to verify behavior and characterize circuits.
A probe-oriented test setup connects test resources to device pads or probe points through card-based instrumentation and measurement paths.
Where it fits in the process flow
General reference — not yet source-verifiedThe ASL 3000 fits in electrical test and probe handling for semiconductor devices rather than in wafer fabrication steps that change material layers.

Frequently asked questions
How are test programs created for these machines?General reference — not yet source-verified
Test programs are developed using the system's proprietary software environment, typically through graphical flow-chart editors or text-based languages like STIL (Standard Test Interface Language). Engineers define test sequences, stimulus parameters, and pass/fail limits for each device type.
What does the test system interface look like?General reference — not yet source-verified
The system connects to the device through a test interface board that carries either a probe card for wafer-level testing or a socket for final packaged testing. The interface provides reliable electrical contact and signal routing between the test head and the device.
What is the typical maintenance requirement for such test systems?General reference — not yet source-verified
Routine maintenance includes periodic calibration of internal instruments, cleaning of contact probes or sockets, and software updates. Preventive maintenance schedules are recommended to ensure measurement accuracy and uptime.
