WebJun 8, 2024 · This is a defect. This defect can be represented by a fault model. In this case, it is a stuck-at-0 fault (as the name suggests) at the gate terminal. We will study stuck-at-faults in detail in later sections. Consequently, the transistor output will always be stuck-at-1 and can be modeled by the same. ... Systematic defects: Crosstalk, process ... Websystematic defect. A defect found in a failing electronic component that is attributed to process variation, such as a metal contact open due to a photomask problem.
