Telindy B Vertical

A vertical furnace is a batch thermal-processing tool used to heat wafers in a controlled ambient for diffusion, oxidation, annealing, and related furnace steps. In fab workflows, it is part of the thermal processing area rather than the lithography or patterning sequence.

A vertical furnace processes wafers in a stacked batch arrangement inside a heated chamber. The vertical orientation helps manage thermal uniformity and wafer loading while the process tube or chamber exposes the wafers to carefully controlled heat and process gases.

In diffusion-oriented use, elevated temperature allows dopant species or other furnace ambients to interact with the wafer surface and near-surface region in a controlled way. The same class of tool is also used for other high-temperature furnace steps that require stable temperature control and repeatable atmospheric conditions.

The Telindy B Vertical belongs in the front-end thermal section of a semiconductor line, where wafer batches undergo furnace processing after earlier wafer preparation and before later pattern-dependent or integration steps. It is used when a batch thermal cycle is preferred over single-wafer processing.

Tools in this class are used for diffusion-related thermal steps and other furnace processes that require controlled high temperature and ambient conditions. Typical applications include dopant drive-in, oxidation, annealing, and similar mature-node wafer heating operations.
