PPT-Ion Implantation Electrostatic accelerators are used to deposit ions in semiconductors

Ion Implantation The semiconductor industry relies on the implanting of impurities in semiconductors doping This is critical in integrated circuit manufacturing One way of doping this is to fire ions into the material from an accelerator with its penetration dependent on the energy hence they can be placed accurately in the material. r.

Major initiatives are well underway for ion accelerators for nuclear astrophysics, such as FRIB, RAON and others.  With the success of SNS, high intensity proton accelerator projects are progressing, such as ESS, PIP-II, Indian SNS, along with ADS ambitions, such as CADS and IADS.  The aim of WG2 is to address the major on-going issues for each type of accelerator, how these issues are being addressed, as well as the needed developments. Demonstrated and needed advances in couplers and tuners for both accelerator classes should be included.  Please avoid presentations that give project status summaries - more suited to other conferences. .

Semiconductor material is a substance which has electrical conductivity between conductors and a non-conductor or insulator. Semiconductors are the core fundamental materials which are used in solid-state electronic devices such as transistors, diodes etc. The material’s atomic structure decides whether the material will turn out to be a metal, semiconductor or insulator. .
