A recently filed patent (Publication Number: US20240027292A1) describes an apparatus comprising a silicon chip with a silicon substrate and a semiconductor strain gauge. The semiconductor strain gauge includes a plurality of resistors formed by locally doping the silicon substrate and junction-isolated by biasing the silicon substrate. Additionally, a field shield layer is included to isolate the output signal of the semiconductor strain gauge from external electrical fields. The resistors are electrically connected in a specific configuration between bond pads, with junctions surrounding each resistor to enhance performance.

Furthermore, the apparatus includes a glass substrate for coupling the silicon substrate to a contact surface, with the glass substrate not in contact with the resistors. Each resistor in the plurality of resistors is a piezoresistive resistor, providing specific functionality to the apparatus. The silicon chip also features sets of tails extending from the center of the top surface beyond the bond pads, allowing for efficient connections. Overall, the patent outlines a detailed design and configuration of the apparatus to optimize its performance and functionality in various applications.
