Benzocyclobutene (BCB) is a benzene ring fused to a cyclobutane ring. It has chemical formula {{chem2|auto=1|C8H8}}.[http://www.sigmaaldrich.com/catalog/search/ProductDetail/ALDRICH/164410 164410 Benzocyclobutene 98%]

BCB is frequently used to create photosensitive polymers. BCB-based polymer dielectrics may be spun on or applied to various substrates for use in Micro Electro-Mechanical Systems (MEMS) and microelectronics processing. Applications include wafer bonding, optical interconnects, low-κ dielectrics, or even intracortical neural implants.
