Abstract
Abstract An electronic module includes multiple stacked bare IC chips ("a stack") and a sensor assembly that is mechanically coupled to an end surface of the stack. Electrical connection between the sensor assembly and the stack is provided by a metallization layer disposed on a side-surface of the stack. Specifically, wiring of the sensor assembly extends to an edge surface thereof corresponding to the side-surface of the stack where it electrically connects to the side-surface wiring. The IC chips of the stack are similarly electrically connected to the side-surface wiring. Multiple sensors (e.g., CCD arrays) may be electrically and mechanically coupled to multiple surfaces of the stack for providing a, e.g., multi-view imaging module. Multiple electrical and mechanical options exist for the connection of sensors to stacks within electronic modules.
