Pure Indium Sputtering Targets

  • Indium Corporation

  • Pure indium sputtering targets are used for some very interesting applications:

    • Indium sputtering targets are commonly used to deposit the indium layers in CIS and CIGS solar cells. These targets can be co-deposited along with copper and gallium, and combined with sulfur/selenium to form the cell’s active layer.
    • Indium sputtering targets can also be reactively sputtered with controlled amounts of O2 and other materials to form transparent conductive oxide (TCO) layers on glass or alternative substrates. These thin films are used to transmit power without obscuring light.
    • Indium sputtering targets are also used in the semiconductor industry to form metallizations which can later be cold welded. Flip-chip packages sometimes incorporate this technology.
