Protech Technology

For low melting point materials, we have developed
casting processes which carefully control
micro structure and uniformity, both of which
are necessary for superior sputtering

Examples are indium (In) and indium alloy
sputtering target casting, used in thin film
solar manufacturing, web coating and
architectural glass coating applications.  
The ProTech Materials' casting process
yields high purity, small grain size, void free
sputtering targets.

Powder processing is another core strength
of ProTech Materials. Our manufacturing
processes are used to consolidate powders
for both metals with high melting points,
as well as, ceramic oxides .  The process steps used in powder based target
manufacturing include powder preparation, cold pressing, hot pressing, cold
isostatic pressing (CIP), hot isostatic pressing (HIP), sintering  and thermal spraying.

Careful control of key parameters in these process steps result in the high quality
materials that ProTech Materials is known for.

An example of one of ProTech's powder manufactured products is ITO (Indium Tin
Oxide).  Our powder and consolidation processes result in a high density sputtering
target with excellent uniformity control, within a lot and lot to

ProTech Materials is continuously improving existing processes and developing new
ones to meet the challenge of the rapidly changing materials needs in each of the
markets we serve.
