A method of reducing the area of MCMs that are integral to a flexible carrier is provided. A locally complex area, i.e. multilayer MCM carrier is constructed on a flex carrier, along with other components to form a subsystem. The flex carrier provides the interface between the MCM and the system that...http://www.google.fr/patents/US5239448?utm_source=gb-gplus-shareBrevet US5239448 - Formulation of multichip modules
