Latest Patents

One of his latest patents is titled "Method and apparatus for securing electronic circuits." This invention provides a method for protecting stored information on an integrated circuit from reverse engineering. The approach involves splitting the functionality of an integrated circuit into two separate integrated circuits, which are interconnected in a secure manner. A detection circuit monitors this interconnection, and if a break is detected, it destroys the data stored in both circuits. This design prevents unauthorized access to the underlying conduction paths and charge storage sites typically exploited in reverse engineering.

Another notable patent is "Flip chip assembly of semiconductor IC chips." This specification outlines techniques for soldering IC chips to interconnection substrates using a patterned epoxy layer. The epoxy layer is photodefined to create openings that expose bonding sites on the IC chip or substrate. Solder paste is then deposited in these openings, and upon alignment and heating, the solder bonds the IC chip to the substrate. This method ensures complete filling of the gap between the IC chip and the substrate, allowing for very fine pitch interconnections.
