TEL NT333™ Vertical Batch Thermal Oxidation Diffusion Furnace Platform

The TEL NT333™ is Tokyo Electron's (TEL) vertical batch thermal oxidation/diffusion furnace platform for wafers 200mm and smaller. It belongs to TEL's mature process thermal processing equipment series, primarily serving power devices, analog chips, and MEMS production lines.

Process Positioning: The NT333 operates in batch mode, processing dozens to hundreds of wafers per tube. It primarily handles high-temperature thermal processing steps such as thermal oxidation (dry/wet oxidation), diffusion, annealing, and alloying. It can also be used for LPCVD thin film deposition. In power device manufacturing, it covers key stages such as gate oxide growth, field oxide formation, and impurity-activated annealing. The batch architecture delivers high throughput and low cost per wafer.

Design Focus: This platform emphasizes temperature uniformity and process stability, featuring independent multi-temperature zone control, supporting both atmospheric and low-pressure processes, and is compatible with 100/150/200mm wafer sizes, facilitating flexible production line switching. The equipment is optimized for mass production scenarios in terms of uptime and ease of maintenance, meeting the core requirements of mature processes for continuous equipment operation.

Positioning Analysis: The NT333 belongs to the same batch furnace family as TEL's ALPHA-8SE™ i and Episode™ series, but the NT333 focuses more on high-temperature heat treatment and oxidation, rather than primarily ALD/CVD film deposition. It belongs to a different track in terms of production capacity and application nodes compared to the single-wafer advanced node ALD/CVD platforms you've previously focused on.

In short, the NT333 is TEL's main high-temperature batch heat treatment platform in mature processes and power semiconductors, and is a fundamental piece of equipment in the thin film deposition and heat treatment process chain.
