Viision 80 Medium Current Ion

Ion implantation is a semiconductor doping tool used to introduce selected ions into a wafer surface in a controlled way. Machines in this class are used to modify electrical properties of materials by placing dopant species into near-surface regions before later thermal processing activates the implanted species and repairs crystal damage.

An ion implanter creates a beam of charged ions, accelerates the ions to a chosen energy, and directs the beam onto the wafer. The implanted dose and energy determine how deeply the ions penetrate and how much dopant is introduced, allowing tightly controlled modification of semiconductor layers.

Medium current implant tools are generally used for production implants that require a balance of beam current, throughput, and dose control. In normal process flow, the implanter follows wafer preparation and masking steps and is followed by annealing or similar thermal treatment.

This class of equipment sits in the doping portion of front end semiconductor manufacturing. It is used after pattern definition or masking steps so that ions are introduced only into selected wafer regions.

After implantation, wafers commonly proceed to thermal processing to activate the dopants and reduce implantation-induced damage. The implanter therefore links masking and layer formation to later device activation steps.

Medium current ion implanters are used for semiconductor doping operations that require controlled ion placement in selected regions of a wafer. They are used in device fabrication flows that need precise adjustment of electrical conductivity and junction characteristics.
