Engineered Material Systems Introduces DF-3020 Antimony Free Dry Film Negative Photoresist

Oct 29, 2013

 DF-3020 Dry Film Negative Photoresist

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-3020 Dry Film Negative Photoresist for use in micro-electro-mechanical systems (MEMS).

This material formulation has been optimized for hot roll lamination and processing on MEMS and IC wafers.

DF-3020 is available for sampling in 20um thickness, ±1 μm and can be manufactured from 5 to 25 μm thick. The cured chemistry can withstand harsh environments including resistance to extreme moisture conditions and corrosive chemicals. The DF-3020 film is tougher (less brittle) than most negative photoresists in the market with a glass transition temperature of 165°C (by DMA Tan Delta) and a moderate modulus of 4 GPa at 25°C. The cured chemistry is hydrophobic in nature, providing chemical and moisture resistance.

DF-3020 is compatible with and can be used in contact with the EMS line of spin coatable photoresists. DF-3020 is the latest addition to Engineered Materials Systems’ full line of film and liquid negative photo resists formulated for making microfluidic channels on MEMS devices and integrated circuits.
