Electroglas 4080X
TOC
About
Process: This is an automated wafer prober used for precise wafer-level electrical testing preparation. It loads the wafer, performs vision-based alignment, and steps across die sites to make contact with a probe card, enabling the connected tester to perform measurements. Hardware: Electroglas 4080X prober (modular: handler + prober control + vision). Configured for 200 mm (8") wafers with hot chuck option. Includes DCM-2 (display/control), MHM (material handler), PCM (prober control), PRM-3 (vision). Key Features:
Wafer size: 100 mm (4″) – 200 mm (8″) standard; ring-carrier adapters up to 300 mm available Chuck type & temp.: Gold-plated vacuum chuck, ambient → +130 °C with TC-2000 controller (standard “hot chuck”) Indexing accuracy/repeatability: ±4 µm X-Y, Z-resolution 0.25 mil (6.3 µm) Throughput: ≤ 1.5 s die-to-die at 5 mm step; lot-level ≈ 60 wph (150 mm) Vision/alignment: PRM-3 CCD camera, Self-Teach Auto Alignment (STAA), optional OCR & Probe-Mark-Inspection (PMI) Interfaces: GPIB-IEEE 488, RS-232, Ethernet, EG-Commander/ProberBench software Applications: Wafer loading, precise alignment, and stepping for parametric/TEG testing Integration with external testers (e.g., Keithley S530) for automated electrical characterization Temperature-controlled probing for device performance at elevated temps High-accuracy die-to-die positioning in production monitoring flows Usage: Load wafer via material handler, initiate alignment (STAA/vision), step to die sites, make probe contact. Controlled externally via interfaces (e.g., from tester software). Clean chuck/stage after use.

Documentation
Training required – contact lab staff (Chandan Ramakrishnaiah or Shivakumar Bhaskaran) Check lab resources for manuals (e.g., EG-Commander/ProberBench guides); no dedicated SOP listed – consider creating one
Recipes & Data
Standard Usage: Automated stepping for PCM/TEG lots; hot chuck for temp-dependent tests Process Control: Use consistent alignment routines; verify probe contact/scrub marks Notes: Interface with tester for full automation (GPIB/RS-232/Ethernet commands). Monitor chuck temp via TC-2000. Template:Under review This article was generated with assistance from a large language model (LLM) and is currently under human review and editing.
