1. Introduction to the TSK UF2000 Prober
The TSK UF2000 is one of the flagship wafer probers developed by Tokyo Seimitsu (now ACCRETECH), a company recognized worldwide for its precision metrology and semiconductor testing solutions. Positioned as a 200 mm-class prober, the UF2000 is designed to handle both production wafer testing and engineering applications, making it suitable for IC manufacturers, research institutions, and specialty device fabs.
When it was introduced, the UF2000 bridged a critical gap between high-accuracy manual probers and fully automated high-throughput systems. Even today, it remains a reliable choice in the secondary equipment market, particularly for fabs that value stability, accuracy, and cost-effectiveness.
2. Core Features of the TSK UF2000
The UF2000 integrates several advanced features that ensure stable performance across a wide range of wafer testing applications.
Key Features at a Glance:
-
Wafer Compatibility: Supports wafers up to 200 mm in diameter.
-
Precision Alignment: High-accuracy optical alignment system ensures consistent contact between probe needles and pads.
-
Automation: Automated wafer handling and chuck movement reduce operator intervention.
-
Flexible Software: Intuitive user interface for recipe management and repeatable test routines.
-
Throughput: Balanced performance designed to support both engineering and mid-volume production.
-
Robust Design: Built to handle continuous use in demanding fab environments.
These features made the UF2000 an attractive investment for fabs requiring versatility and long-term reliability.
3. Technical Specifications of the TSK UF2000
The following table summarizes the main technical parameters of the UF2000:
| Specification | Details |
|---|---|
| Wafer Size Support | Up to 200 mm |
| Chuck Options | Thermal chucks (hot/cold) available; supports various device testing needs |
| Alignment Accuracy | ±1 µm (typical), ensuring reliable pad-to-needle contact |
| Repeatability | High stability across long test cycles |
| Probing Force | Adjustable, compatible with different probe cards |
| Throughput | Mid-range UPH (Units per Hour), suitable for R&D and production |
| Software Control | Recipe-driven, user-friendly GUI |
| Maintenance Cycle | Designed for low downtime, predictable preventive maintenance |
Interpretation of the Specs
-
The 200 mm wafer compatibility makes it ideal for fabs that are still producing at sub-200 mm nodes or running specialty devices.
-
Alignment precision of ±1 µm ensures yield consistency, particularly important for fine-pitch IC devices.
-
With thermal chuck options, the UF2000 can support temperature-dependent electrical tests, which are increasingly relevant in power devices and MEMS applications.
