Patent number: 11486911Abstract: Detecting voltage-based attacks on an integrated circuit (IC) is difficult in the presence of clock jitter. Propagating signals can exhibit a total delay that is due to a delay component resulting from a voltage-based attack and a delay characteristic resulting from clock fluctuation. Voltage-variation detection circuitry includes first and second voltage-dependent circuits and a voltage analysis circuit. The voltage-dependent circuits produce first and second signals that are indicative of a voltage level responsive to a clock signal and based on different first and second voltage sensitivities. The voltage analysis circuit generates a voltage alert signal based on the first and second signals. A combined signal neutralizes the delay characteristic in the first and second signals, but the delay component due to the voltage variation can be at least partially maintained. Thus, a voltage-based attack is detectable in the presence of clock fluctuation by using two voltage-dependent circuits.Type: GrantFiled: July 22, 2020Date of Patent: November 1, 2022Assignee: Google LLCInventors: Emre Tuncer, Huachang Xu, Ramprasad Raghavan, Fanny Gur, Manish Harnur

Patent number: 11443991Abstract: Test pad structures and methods of forming a test pad are described herein. A method for forming a test pad includes forming a device element over a substrate, depositing a dielectric layer over the device element and the substrate, and etching openings in the dielectric layer to a first depth. Once the openings have been formed, a conductive material is deposited in the openings and followed by a chemical mechanical planarization to form a first grid feature and a panel region of the test pad, the first grid feature extending lengthwise from the panel region to a perimeter of the test pad. Once formed, a probe may be used to contact the panel region of the test pad during a wafer acceptance test (WAT) and/or a process control monitoring (PCM) test of the device element.Type: GrantFiled: May 29, 2020Date of Patent: September 13, 2022Assignee: TAIWAN SEMICONDUCTOR MANUFACTURING CO., LTD.Inventors: Yao-Te Huang, Liang-Chor Chung
