  • Patent number: 12046600
    Abstract: Techniques are disclosed for achieving multiple fin dimensions on a single die or semiconductor substrate. In some cases, multiple fin dimensions are achieved by lithographically defining (e.g., hardmasking and patterning) areas to be trimmed using a trim etch process, leaving the remainder of the die unaffected. In some such cases, the trim etch is performed on only the channel regions of the fins, when such channel regions are re-exposed during a replacement gate process. The trim etch may narrow the width of the fins being trimmed (or just the channel region of such fins) by 2-6 nm, for example. Alternatively, or in addition, the trim may reduce the height of the fins. The techniques can include any number of patterning and trimming processes to enable a variety of fin dimensions and/or fin channel dimensions on a given die, which may be useful for integrated circuit and system-on-chip (SOC) applications.
