Provisional entry — research in progress
This page was generated automatically from cited public sources and hasn't completed the full research pass yet. Every specification shown carries its source; more detail is added as research completes.
What it is
General reference — not yet source-verifiedThe Tokyo Electron Alpha 805 is a thermal processing furnace in the diffusion equipment class.
How it works
General reference — not yet source-verifiedA thermal diffusion furnace heats wafers in a controlled process chamber so that heat-driven film growth or dopant movement can occur on wafer surfaces and within near-surface regions.
A vertical furnace architecture typically loads wafers in a stacked arrangement within a heated tube or chamber to promote uniform thermal processing across the wafer batch.
Where it fits in the process flow
General reference — not yet source-verifiedA furnace of this class sits in the front end of semiconductor wafer processing, after substrate preparation and before later patterning and interconnect formation.
