SU-8 3000
Part of the StructSure™ Line
SU-8 3000 is a high contrast, epoxy-based photoresist designed for micro-machining and other microelectronic applications, where a thick, chemically and thermally stable image is desired. SU-8 3000 is an improved formulation of SU-8 and SU-8 2000, which has been widely used by MEMS producers for many years. SU-8 3000 has been formulated for improved adhesion and reduced coating stress. The viscosity range of SU-8 3000 allows for film thicknesses of 4 to 100 μm in a single coat. SU-8 3000 has excellent imaging characteristics and is capable of producing very high, over 5:1 aspect ratio structures. SU-8 3000 has very high optical transmission above 360 nm, which makes it ideally suited for imaging near vertical sidewalls in very thick films. SU-8 3000 is best suited for permanent applications where it is imaged, cured and left on the device.
