Popis: Flexible materials, today, are being used already as base substrates for electronic assembly. A lot of mounted components could be integrated in flexible polyimide (PI) substrates. Very interesting advantages of integrating components into the flex are compactness and enhanced flexibility; not only the interconnection but also the components themselves can be mechanically flexible. This paper describes a PI-based embedding technology for integrating very thin silicon chips in between two spin-on PI layers, the ultra-thin chip package (UTCP). This paper discusses the different process steps in the UTCP production and also presents the interconnection test results realized with this technology.
