This study was commissioned as a follow-up to the European Investment Bank InnovFin Advisory study of Access-to-Finance Conditions for Key Enabling Technologies companies in 2015. It carries out a mapping of the key access-to-finance conditions for companies working in the photonics and micro-electronics/components sectors in Europe. Furthermore, the report explores to what extent the conclusions drawn and recommendations made for KETs (Key Enabling Technologies) companies in general also apply to photonics and semiconductor companies and identifies the need for more targeted measures.
