Engineered Material Systems Introduces DF-3005 Dry Film Negative Photoresist
Engineered Material System is pleased to introduce the DF-3005 Dry Film Negative Photo Resist for use in micro-electromechanical 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-3005 is available in other thickness formats from 5-50 µm, ±5 percent. The cured chemistry can withstand harsh environments including resistance to extreme moisture conditions and corrosive chemicals. The DF-3005 film is tougher (less brittle) than most negative photo resists 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-3005 is compatible with and can be used in contact with the EMS line of spin coatable photoresists.
DF-3005 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.
