What it is
The VIISta HE XP is an ion implantation system produced by Applied Materials (formerly Varian Semiconductor Equipment). The VIISta HE XP is a high-current implanter.[1][2]
How it works
General reference — not yet source-verifiedIon implanters generate a beam of dopant ions from a source gas, accelerate the ions to a desired energy, and then scan the beam across the wafer surface to achieve a uniform implanted dose. High-current implanters typically use a ribbon beam or a spot beam that is mechanically scanned across the wafer to achieve high throughput.
Where it fits in the process flow
General reference — not yet source-verifiedIon implantation is a critical step in the fabrication of integrated circuits, typically performed after photolithography and before annealing. High-current implanters are used for source/drain doping, polysilicon gate doping, and other high-dose applications that require heavy concentrations of dopants.
Applications
General reference — not yet source-verifiedThe primary application of high-current ion implanters is for high-dose doping of silicon wafers in CMOS logic and memory device fabrication. Typical implanted species include boron, phosphorus, and arsenic for p-type and n-type doping.
