Engineered Material Systems Debuts DF-3050 Dry Film Negative Photoresist


Reading time ( words)

Engineered Material Systems, Inc., a leading global supplier of negative photo resist materials for MEMS and IC cooling applications, is pleased to introduce the DF-3050 Dry-film Negative Photoresist for use in micro electro mechanical systems (MEMS) and wafer-level packaging applications (TSV sealing). This material formulation has been optimized for hot roll lamination and processing on MEMS and IC wafers.

DF-3050 is available in other thickness formats from 5 to 50um, ±5 percent. The cured chemistry can withstand harsh environments including resistance to extreme moisture conditions and corrosive chemicals. The DF-3050 film is tougher (less brittle) than most negative photoresists on the market with a glass transition temperature of 158°C (By DMA Tan Delta) and a moderate modulus of 3.5 GPa at 25°C. It is hydrophobic in nature providing for chemical and moisture resistance. DF-3050 is compatible with and can be used in contact with the EMS line of spin coatable photoresists.

DF-3050 is the latest addition to Engineered Materials Systems’ full line of film and liquid negative photoresists formulated for making microfluidic channels on MEMS devices and integrated circuits.
