Used TEL Track System MARK Vz

The TEL MARK Vz is a fully automated track system designed for 200mm (8-inch) wafers. As part of Tokyo Electron’s (TEL) classic MARK series, it serves as a highly reliable, high-volume production platform for 8-inch lithography processes.

Core Positioning: A High-Stability, High-Throughput Lithography Hub

This system integrates key lithography-related processes, including photoresist spin-coating, soft baking, post-exposure baking (PEB), developing, and hard baking. It is primarily utilized in production lines for mature-node technologies—such as power semiconductors, analog chips, MEMS, and compound semiconductors—where it ensures process consistency before and after exposure, playing a critical role in maintaining critical dimension (CD) uniformity.

Key Technical Features

Modular Cluster Architecture: The system features a flexible combination of coating, hot plate, cooling, and developing units, supporting parallel processing across multiple chambers. A central robotic handler facilitates high-speed wafer transport, which can be optimized based on production line takt time to achieve high throughput and high equipment utilization.

Precision Thermal and Fluid Management: Multi-zone, independently controlled hot plates ensure uniform baking and minimize pattern distortion. The coating and developing units incorporate precise control over spin speed and chemical flow rates, guaranteeing uniform photoresist thickness and stable development processes.

High-Cleanliness Automated Integration: The system includes an integrated "mini-environment" to prevent particle contamination. It supports automated wafer-carrier loading/unloading and SECS/GEM communication, allowing for seamless integration with various stepper/scanner lithography tools within fully automated production lines.

Summary

With its mature coating and developing processes, flexible modular configuration, and exceptional automation capabilities, the MARK Vz serves as an essential piece of equipment for ensuring lithography yield and production efficiency in 200mm mature-node and specialty-process manufacturing lines.
