Sputtering Targets

Aluminium Chromium Alloy Sputtering Target is a technique used deposite thin films of a material onto a surface. There are many different ways to deposite materials such as metals , plastic and ceramics. Aluminum coating found on telescopes, automotive headlamps, mirrors, etc. it is widely used in the aerospace, automotive lighting,OLED etc.

Aluminium Chromium Alloy Sputtering Target primary market is sputtering targets used to make interconnects for integrated circuits. For some applications the impurities uranium and thorium are reduced to less than 1 ppbw to avoid “soft errors” associated with α particle emission. The crystallization process achieves segregation coefficients which are close to theoretical at normal yields, and this, coupled with the scale of the units, allows practical production of this material. The silicon purification process involves crystallization of Si from molten aluminum alloys containing about 30% silicon.

Aluminium Chromium Alloy Sputtering Target crystallites from this process are further treated to remove residual Al and an extreme purity ingot is obtained. This material is considered suitable for single crystal or ribbon type photovoltaic cells and for certain IC applications, including highly doped substrates used for epitaxial growth. In production of both extreme purity Al and Si, impurities are rejected to the remaining melt as the crystals form and some separation is achieved by draining this downgraded melt from the unit.
