Hitachi Kokusai DD 803 V Annealing is an annealing furnace. Hitachi Kokusai DD 803 V Annealing is categorized as Thermal / Diffusion.[1][2]
What it is
How it works
General reference — not yet source-verifiedAnnealing furnaces process wafers by placing them in a temperature-controlled chamber or tube and holding them through a defined thermal cycle. Annealing furnaces commonly use controlled ambient gases to manage oxidation, reduction, inert heating, or other thermal conditions during the recipe.
Where it fits in the process flow
General reference — not yet source-verifiedAnnealing furnaces sit in the thermal portion of the semiconductor line and are used after steps that leave implanted dopants, deposited films, or thermally stressed structures that need a heat treatment. Annealing commonly fits between front-end fabrication steps and later patterning, deposition, or contact-formation steps, depending on the device flow.
Applications
General reference — not yet source-verifiedAnnealing furnaces are used for post-implant dopant activation, defect reduction, film densification, interface improvement, and stress relief in semiconductor structures. Annealing furnaces are also used when a process requires controlled heating to tune electrical behavior or material stability before subsequent fabrication steps.
