DTU DANCHIP is an open access facility for reserach, development and small-scale production within micro- and nano-fabrication. We are a national centre located at and fully owned by the Technical University of Denmark (DTU). We operate and maintain open access state-of-the-art processing equipment and cleanroom facilities to enable optimum processing within broad technology areas. We facilitate innovation in an environment where researchers, small and medium sized enterprises as well as large established firms can directly access our state of the art fabrication equipment. We provide a comprenhensive and expanding selection of state-of-the-art process equipment for lithography, etching, thermal processing, thin film deposition, wafer cleaning, packaging and characterisation, which are professionally maintained by our team of technicians and process engineers. We conduct research and insource development and small scale production projects thereby opening a pathway to customized micro- and nanosystems without large investments into equipment and facilities. Our 250 registered users work in the areas of education, research, development, prototyping, and small scale production. Our staff of more than 40 employees is dedicated to quality and service.
