  • Publication number: 20220328475
    Abstract: Transistors of different types of electronic devices on the same semiconductor substrate are configured with different transistor attributes to increase the performance of the different types of electronic devices. Fin height, shallow source drain (SSD) height, source or drain width, and/or one or more other transistor attributes may be co-optimized for the different types of electronic devices by various semiconductor manufacturing processes such as etching, lithography, process loading, and/or masking, among other examples. This enables the performance of a plurality of types of electronic devices on the same semiconductor substrate to be increased.
