  • Patent number: 12165875
    Abstract: Recesses may be formed in portions of an ILD layer of a semiconductor device in a highly uniform manner. Uniformity in depths of the recesses may be increased by configuring flows of gases in an etch tool to promote uniformity of etch rates (and thus, etch depth) across the semiconductor device, from semiconductor device to semiconductor device, and/or from wafer to wafer. In particular, the flow rates of gases at various inlets of the etch tool may be optimized to provide recess depth tuning, which increases the process window for forming the recesses in the portions of the ILD layer. In this way, the increased uniformity of the recesses in the portions of the ILD layer enables highly uniform capping layers to be formed in the recesses.
