AME Chip Heatsink Capacitor
Verified
A first design is finished, a complete explanation of the targeted functionality is included, and the targeted printer technology has been provided. This AME design also provides a model which is proven to fulfill the targeted functionality. Furthermore, the AME structure has been printed and validated by measurements. A complete set of the measurement setup and results is provided.
This design can be used for hardware IT-security issues, to protect a semiconductor chip against espionage, and reverse engineering by opening a chip housing.
AME can provide bare chips with individually printed housing.
Active chips with dissipation power represent a potential hotspot for thermal aspects. The 3-dimensional footprint for chip assembly shall transport heat from this hotspot to the outer area. (first use case)
Using AME technology within the heatsink design, electronic functionality can be created. By designing different conductive structures, capacitor performance also relies on the heatsink. In addition to the heatsink thermal function, a measurable capacitance can be produced. (second use case)
If the heatsink with the capacitor is damaged or cracked, an open or shorted circuit is immediately replaced by the expected capacitance. This electronic stage can be detected and can help to identify unwanted threads on the semiconductor assembly.
