Accretech / TSK AP3000e Wafer Prober | High-Precision, High-Throughput Semiconductor Testing

Introduction to the Accretech / TSK AP3000e Wafer Prober

In semiconductor manufacturing, wafer probers play a vital role by bridging the gap between wafer fabrication and final device testing. They ensure that each die on a wafer can be electrically evaluated before packaging, helping manufacturers detect defects early and optimize yield. Among the many systems available, the Accretech / TSK AP3000e stands out as one of the most advanced and reliable probing platforms.

Designed for both research laboratories and high-volume fabs, the AP3000e combines high precision mechanics, robust automation, and intelligent software to deliver consistent results in demanding testing environments. For companies that must balance accuracy, throughput, and cost-effectiveness, this model represents an industry benchmark.

Design Philosophy and Core Performance

The AP3000e was developed with a design philosophy that emphasizes accuracy, stability, and usability. At its core, it integrates a next-generation motion control system that minimizes vibration and noise, ensuring reliable measurements even when probing extremely fine structures.

• High Precision Mechanics – Advanced alignment stages and Heidenhain scale systems provide nanometer-level positioning accuracy.

• Low Noise Operation – Quiet chuck and stage operation are ideal for sensitive electrical measurements.

• Recipe and Map Compatibility – Full backward compatibility with earlier Accretech systems allows easy migration of testing data and processes.

• User-Centric Design – Control interfaces are intuitive, reducing training time and operator errors.

Together, these characteristics allow semiconductor engineers to focus on process optimization rather than machine calibration.

Throughput and Efficiency Enhancements

Beyond accuracy, the AP3000e is engineered for throughput efficiency, a key metric in high-volume semiconductor testing. Its dual robotic wafer handling arms, advanced pre-alignment stages, and optimized indexing movements shorten cycle times without compromising stability.

Typical efficiency-enhancing features include:

• Automated Wafer Handling – Compatible with single or dual loaders, as well as AMHS (Automated Material Handling System) integration.

• Fast Alignment Routines – Advanced optical systems reduce alignment time per wafer.

• Reduced Downtime – Options such as automatic needle cleaning and probe card exchange minimize manual intervention.

The following table summarizes how the AP3000e addresses efficiency compared with standard wafer probers:

This combination of speed and consistency makes the AP3000e a preferred choice for fabs aiming to maximize both testing throughput and operational reliability.

Software and Security Features

Modern wafer probers are no longer just mechanical tools; they are integrated digital platforms. The AP3000e reflects this transition by offering software features that enhance both usability and system security.

One of the most notable aspects is the pre-installed antivirus and anti-malware protection, which safeguards testing environments against cybersecurity threats. As wafer probers are often networked across fabs, this level of protection is essential for data integrity.

In addition, the graphical user interface (GUI) has been designed with clarity and accessibility in mind. Operators can quickly set up recipes, monitor test progress, and analyze wafer maps without steep learning curves.

• Intuitive Operation – Clear menus and real-time wafer mapping.

• Recipe Management – Easy storage, retrieval, and compatibility with legacy formats.

• Automated Calibration – Built-in functions for needle height and probe-to-pad alignment.

• Secure Connectivity – Support for fab-wide data sharing without compromising safety.

This software-centric approach ensures that even in complex testing environments, the operator experience remains smooth and reliable.

Flexible Hardware Configurations

Another reason the AP3000e is widely adopted is its hardware flexibility. Instead of offering a fixed configuration, Accretech designed the system to be modular, allowing fabs to tailor it to their own testing needs.

• Chuck Systems:

  • Ambient chucks for standard testing

  • Hot temperature (up to 200°C) for reliability and stress tests

  • Low temperature or low noise chucks for specialized applications

• Loader Options:

  • Standard dual loader

  • Integration with AMHS for automated wafer transport

• ID Recognition Systems:

  • Wafer ID reading (top or back surface)

  • Cassette ID reading for enhanced traceability

The following table illustrates the modular hardware choices:

By offering this range of configurations, the AP3000e can serve both R&D labs requiring versatility and production fabs demanding full automation.

Advanced Probing and Measurement Options

Testing requirements in the semiconductor industry are becoming more complex, and the AP3000e addresses this with a suite of advanced probing options. These enhancements not only increase measurement accuracy but also reduce operator workload.

Key options include:

• Automatic Needle Cleaning – Utilizes either a cleaning wafer or ceramic block, ensuring consistent contact quality.

• APC (Auto Probe Card Exchange) – Reduces downtime by enabling automated card replacement.

• Probe Card Auto Setup (PCAS) – Simplifies probe card alignment, significantly reducing setup time.

• Multi-Site Parallel Probing – Supports up to thousands of sites, ideal for high-volume production.

• Probe Mark Inspection – Ensures contact quality and prevents false test results.

For fabs that demand the highest efficiency, these advanced probing systems provide a competitive advantage by enabling faster, cleaner, and more consistent testing cycles.

Networking and System Integration

In today’s semiconductor fabs, no system works in isolation. The AP3000e is designed with networking and communication interfaces that allow seamless integration into existing manufacturing ecosystems.

Supported features include:

• Prober Network Options – Compatibility with Veganet, Light-Veganet, and Vega-Planet systems.

• Standard Protocols – GEM interface for fab-level equipment communication.

• Tester Connectivity – GP-IB and Ethernet interfaces ensure compatibility with a wide range of testers.

• Real-Time Data Sharing – Wafer maps and yield data can be shared instantly across systems for analysis.

This connectivity makes the AP3000e especially valuable in smart factory environments, where data-driven process optimization is critical.

Applications in Semiconductor Manufacturing

The AP3000e is versatile enough to serve multiple stages of semiconductor production. Its precision, speed, and automation options make it suitable for:

• Research and Development (R&D) – High precision alignment and customizable chuck options support advanced device testing.

• Pilot Line Production – Flexibility in configuration allows efficient transition from development to limited production.

• High-Volume Manufacturing (HVM) – Automation readiness (AMHS, APC, PCAS) ensures stability and throughput in 24/7 fabs.

• Advanced Technology Nodes – Low vibration and accurate probing enable testing of fine-pitch devices and high-density wafers.

This adaptability explains why the AP3000e remains a long-term investment for both emerging semiconductor companies and global tier-one manufacturers.

Why Choose the AP3000e for Modern Fabs
