With a total of 4 patents to his name, Cestero's work reflects a commitment to advancing innovation.

Latest Patents

Cestero's latest patents include groundbreaking technologies. One of his notable inventions is a retention-based intrinsic fingerprint identification system that utilizes a fuzzy algorithm and a dynamic key. This system employs a random intrinsic chip ID generation that incorporates a retention fail signature. The process involves generating a 1ID and 2ID using testing settings, with the 1ID being more restrictive than the 2ID. This innovative approach enhances security by controlling the number of retention fails through a BIST engine, ensuring that the ID used for authentication is reliable.

Another significant patent is the method of programming electrical antifuses. This invention allows an antifuse, which includes a region of unsilicided semiconductor material, to be programmed at reduced voltage and current. This method minimizes heat generation and electromigration of metal or silicide, resulting in an alloy with reduced bulk resistance. The design of the cathode and anode is optimized to control the regions from which material is electrically migrated, making the process compatible with the fabrication of field effect transistors.
