Morgan Technical Ceramics (MTC), a leading manufacturer of innovative ceramic, glass, precious metal, piezoelectric and dielectric materials, will exhibit at booth # 6458 at Semicon West, to be held at The Moscone Center, San Francisco, CA from July 14-16, 2009. MTC will showcase its line of fused silica rollers and PBN crucibles, which are ideal for a wide variety of market applications.

The Bolt Technical Ceramics business of MTC will be exhibiting its line of Fused Silica Rollers. Traditionally used for handling sheet glass for automobiles, appliances and architectural applications, these high quality fused silica rollers are now being used in the manufacturing of solar cells. The outstanding mechanical properties and special surface quality of the fused silica rollers make them ideal for use as transport rollers for tempering flat glass, as well as for use in both diffusion and thin film processing of solar panels.

The fused silica rollers move hot glass panels through the deposition process used in manufacturing thin film photovoltaic (TFPV) cells. The thermal stability of this complex component is exceptional; it has a coefficient of thermal expansion (CTE) of <1 x 10-6/°C – lower than any other ceramic material. This low CTE combined with its chemical compatibility with glass makes fused silica rollers an ideal choice for ensuring the glass panels remain flat during the manufacturing process.

In addition, Morgan Technical Ceramics’ CVD Materials business (MTC – CVD) will be exhibiting its Performance® Pyrolytic Boron Nitride (PBN) material for use in manufacturing the photo absorption layer in thin film photovoltaic (TFPV) cells. Performance PBN is an excellent material for crucibles and evaporation boats used in producing the TFPV cells, as well as for coating graphite heating elements used for material vaporization.

In the TFPV deposition process, precursor vapors are transported from a source vessel into a deposition zone onto a heated substrate to deposit the PV layer. In some instances, solid materials are melted and vaporized from ceramic crucibles or boats to form a flux that is deposited on the heated substrate. It is critical that the ceramic crucible or boat be dimensionally stable and chemically non-reactive to the molten source material. PBN ceramic is an excellent material because of its high corrosion resistance and non-reactivity with the source materials used in PV deposition.
