What it is

The Nitto Kagaku NHK 170 AF is an electric furnace. The furnace is classified as thermal/diffusion equipment.[1][2]

How it works

General reference — not yet source-verified

Diffusion furnaces operate by heating a quartz tube or chamber with resistive heating elements. Wafers loaded into a quartz boat are placed inside the tube, and process gases are introduced to achieve the desired chemical reactions at elevated temperatures. Temperature profiles are tightly controlled to ensure uniform processing across the wafer batch.
