What it is
General reference — not yet source-verifiedThe Hitachi Kokusai DD 802 V H is a semiconductor manufacturing machine in the thermal and diffusion category.
How it works
General reference — not yet source-verifiedA thermal diffusion furnace is used to heat wafers in a controlled process environment so atoms can move into or through the surface of the semiconductor substrate.
A machine in this class is generally used for heat-driven wafer processes such as dopant diffusion and related thermal treatments that depend on uniform temperature control and process-gas management.
Where it fits in the process flow
General reference — not yet source-verifiedA diffusion furnace sits in the wafer fabrication flow after patterning steps that define where material modification is needed.
A diffusion furnace is used before later electrical completion steps that depend on the thermal formation of regions in the wafer.
Applications
General reference — not yet source-verifiedThermal diffusion equipment is used for semiconductor wafer processing tasks that require controlled high-temperature exposure.
Thermal diffusion equipment is used for dopant introduction and other heat-based substrate treatments in mature-node semiconductor manufacturing.
