IR15: Designed for straight profiles when used as negative photoresist

IR15 Lift-Off: Designed for lift-off profiles when used as negative photoresist

HARE SQ™ is a negative tone epoxy photoresist designed for polymeric MEMS, microfluidics, micromachining and other microelectronic applications. This resist has excellent chemical, mechanical and thermal resistance, making it suitable for permanent applications. It is fully compatible with SU-8™ processes. It is sensitive to NUV, i-line and broadband wavelengths. HARE SQ uses superior epoxies specially designed for the electronics industry, making improvements in optical transparency, particles and filter-ability, cured surface energy consistency, and photoresist lot-to-lot consistency versus industry competitors.

HARP™ PMMA (polymethyl methacrylate) e-Beam resist is designed for high resolution direct write e-Beam lithography. When combined with HARP-C™ copolymer, the HARP™ multi-layer system is ideal for T-gate manufacture. HARP™ PMMA has excellent adhesion to a wide variety of substrates, and is used as a protective coating layer for wafer thinning and sacrificial layers. KemLab HARP™ PMMA products are manufactured in safe solvents (anisole and ethyl lactate).
