Varian E 500 Medium Current is a medium current ion implanter designed for 8-inch wafers. Varian E 500 Medium Current was introduced around 1996.[1]
What it is
The Varian E 500 Medium Current is an ion implantation system used in semiconductor manufacturing.[1][2]
How it works
General reference — not yet source-verifiedIon implanters of the medium-current class direct a beam of dopant ions at a semiconductor wafer, embedding the ions into the substrate to alter its electrical properties.
The machine accelerates the ion beam through an electric field to achieve a desired energy, then scans the beam or the wafer to achieve uniform doping across the wafer surface.
Where it fits in the process flow
General reference — not yet source-verifiedIon implantation is a doping step performed after the wafer has been cleaned and patterned with photoresist.
After implantation, the wafer typically undergoes an annealing step to activate the dopants and repair crystal damage caused by the implant.
Applications
General reference — not yet source-verifiedThe Varian E 500 Medium Current is used for doping silicon wafers with dopant species such as boron, phosphorus, and arsenic.
