Engineered Material Systems, Inc., a leading global supplier of negative photo resist materials for MEMS and TSV passivation/sealing applications, is pleased to introduce the DF-4014 dry-film negative photoresist for use in micro-electro mechanical systems (MEMS), wafer-level packaging and CMOS applications (TSV sealing). This material formulation has been optimized for hot roll lamination and processing on MEMS and IC wafers.
The cured chemistry can withstand harsh environments including resistance to extreme moisture conditions and corrosive chemicals.
DF4014 is extremely hydrophobic in nature, providing chemical and moisture resistance. Water will form a contact angle on the surface at > 90°. It is tougher (less brittle) than most negative photoresists on the market with a glass transition temperature of 145°C (By DMA Tan Delta) and a moderate modulus of 4.5 GPa at 25°C. DF-4014 is compatible with and can be used in contact with the EMS line of spin-coatable photoresists.
DF-4014 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.
