  • Patent number: 11222826
    Abstract: A cut-last process for cutting fin segments of a FinFET structure on a substrate utilizes a two-step process. After the fins are formed, an oxide material is deposited in the trenches of the FinFET structure. The oxide material can be an STI oxide or a low-stress dummy gapfill material. A fin segment can be removed by an etchant and can leave a concave shaped (such as a u-shape or v-shape) portion of silicon at the bottom of the fin. Where the oxide material is an STI oxide, the void left by removing the fin can be filled with replacement STI oxide. Where the oxide material is a dummy gapfill material, the dummy gapfill material can be removed and replaced with an STI oxide or converted to an STI oxide and filled with replacement STI oxide before or after the conversion.
