Abstract
Progress of Active interposer (AIP) which is conversion module between electrical and optical signal is described. AIP is a module by which LSI, VCSEL, and the driver, etc. are three-dimensionally mounted on the interposer substrate, and which is one of development technologies of national project “Research and Development for Super High-density Electronics System Integration”. The model was made for trial purposes aiming at the confirmation of a fundamental structure, and the signal transmission characteristic was evaluated
