WebApr 11, 2024 · Line edge roughness, or LER, is defined as a deviation of a feature edge from an ideal shape. Semiconductor features are not perfectly smooth. LER describes the amount of variation on the edges of features, according to Fractilia, a startup that develops measuring techniques for LER. At 10nm and below, LER can become as large as the … WebThe shorter the chip line width the faster the chip since more transistors can be placed on a chip and the data and instructions travel shorter distances during processing. complex …
