Abstract: A three dimensional packaging architecture for ultimate high performance computers and methods for fabricating thereof are described. The package allows very dense packaging of multiple integrated circuit chips for minimum communication distances and maximum clock speeds of the computer. The packaging structure is formed from a plurality of subassemblies. Each subassembly is formed from a substrate which has on at least one side thereof at least one integrated circuit device. Between adjacent subassemblies there is disposed a second substrate. There are electrical interconnection means to electrically interconnect contact locations on the subassembly to contact locations on the second substrate. The electrical interconnection means can be solder mounds, wire bonds and the like. The first substrate provides electrical signal intercommunication between the electronic devices and each subassembly. The second substrate provides ground and power distribution to the plurality of subassemblies.

Abstract: A control system for a blind microwave radiation tool a workpiece is described. The controlled system automatically tunes the cavity containing the workpiece. The control system automatically controls the temperature of the workpiece according to a predetermined temperature versus time schedule. Control system automatically determines when the workpiece has reached a particular predetermined physical condition. To achieve these results the control system automatically monitors applied power, reflected power or current temperature and automatically controls the microwave antennae location and the cavity short location in order to maintain the cavity in resonance and to determine when to exit without operator intervention. Control system can run on a small computer and is useful for automatically curing polyamic acid to polyimide to a predetermined percent cure automatically without operator intervention.
