EMS: Negative Photoresist for MEMS and IC Wafers


Delaware, OH — Engineered Materi- al Systems has introduced its DF- 35120 dry-film negative photoresist for use in microelectromechanical systems (MEMS), wafer-level pack- aging and CMOS applications (TSV


MEMS devices and ICs. The cured chemistry can with-


stand harsh environments, with its resistance to extreme moisture con- ditions and corrosive chemicals. The material is extremely hydrophobic and tough, with a glass transition temperature of 145°C (293°F). It has a moderate modulus of 4.5 GPa at 25°C (77°F). DF-35120 is compatible with the company’s line of spin-coat-


able photoresists. Contact: Engineered Materials

Time to save


Time is money. Time saved in engineering can lower costs or be used to generate more revenue. Switching to EPLAN Electric P8 from CAD software typically reduces project time by 40% or more right out of the box – as much as 80% when this feature- rich electrical CAE is used to its fullest.
