Wafer implantation, also called "ion implantation", is a process that uses elemental ions to change the physical, chemical, or electrical properties of a target. Wafer implantation originated in the 1940s. However, it is most common in the semiconductor industry today. During the wafer implantation process, the ions are accelerated in the electric field to produce a beam emitted at the wafer. Ion implantation allows very precise quantification, which can make the position and depth of the particles on the target wafer more precise.

Alfa Chemistry provides wafer implant services for silicon, silicon-on-insulator (SOI) and other types of specialty substrates such as GaAs, GaN, InP, and more.

Alfa Chemistry's Wafer Implant Capabilities

Alfa Chemistry is a recognized leader in semiconductor wafer ion implantation. We have a dedicated professional department and expert team to help you at any time. We process unique shapes and wafer sizes ranging from pieces to 300 mm.

  • Wafer diameter: 25 mm to 300 mm
  • Implant energy range: 1 KeV to 3 000 KeV
  • Wafer materials: Si, Si thin wafers / Taiko wafers, SiC, GaN, InP / GaAs, InSb, HgCdTe, LiNbO3, Sapphire / Diamond / Quartz
  • Provide low, medium and high dose implant solutions
  • Implantation can be provided on bare and patterned wafer substrates
  • Small batches of prototypes can be accepted (Implantation is a small batch process and is usually more expensive than other standard services.)
  • The following contains a partial list of species that are regularly implanted:
