Downscaled Assembly of Vertically Interconnected Devices

Project description


Technologies and devices for micro/nano-scale integration

The DAVID project targets to provide an extremely high packaging density for hybrid integration of MEMS with ASICs. A significant reduction of assembly and packaging costs, specifically for consumer applications, shall be reached by the integration approach itself, but also by a lithographic size reduction of micromachined structures. The benefit becomes most visible when several sensors are clustered in a single, hermetic encapsulation on wafer level.
Beyond this, a "3D-SiP" approach can improve product quality by reducing parasitic effects: DAVID's extremely short interconnects are particularly interesting for capacitive or high-frequency signals.
The project is designed to demonstrate a complete process flow with the following technology components: - vertical interconnect by post-CMOS feedthroughs- handling, assembly and waferlevel bonding of singulated, open MEMS devices on a CMOS wafer- vacuum sealing and fine structured getter films to control the sensor cavity ambient- waferlevel molding and solder balling to build a chip-scale MEMS-SiP.
Critical aspect like mechanical drift and offset effects of package stress are addressed by the implementation of a test vehicle that allows to measure and correlate them with FEM simulations. A control of design and material suitability is therefore given through all process stages.
The project consortium forms a representative industrial environment: ST Microelectronics as a large semiconductor manufacturer acts close to high-volume market requirements. Datacon Technology and Besi Molding provide industrial equipment for assembly and packaging. SAES Getters is a renowned service provider in vacuum technology. Research and design support is given by Fraunhofer ISIT and Wroclaw University of Technology.
