Abstract: A shallow trench isolation (STI) structure is formed from a conventional STI trench structure of a first dielectric material extending into the substrate. The conventional STI structure undergoes further processing: removing a first portion of the dielectric material and adjacent portions of the semiconductor substrate to create a first recess, and then removing another portion of the dielectric material to create a second recess in just the dielectric material. A nitride spacer layer is formed above the remaining dielectric material and on the sidewalls of the substrate. A second dielectric material is formed on the spacer layer and fills the remainder of first and second recesses to a lever above the substrate. A nitride capping layer and another dielectric layer are disposed above the second material, thereby substantially encasing the STI structure in nitride. This provides a taller STI structure that results in a better fin profile during a subsequent fin reveal process.

Abstract: A method to address overlay accuracy compensation using finFET cut isolation revisions is disclosed. For an integrated circuit (IC) layout including at least a portion of an active region including a plurality of gates extending over a plurality of fins, prior to optical proximity correction of the IC layout: the method determines a number of fins to be cut with same source/drain connection by a fin cut isolation opening, and determines a fin cut isolation pitch in the gate length direction of the plurality of gates. The method revises a size of a fin cut isolation opening in the IC layout based on a number of fins to be cut with same source/drain connection by the fin cut isolation opening and the fin cut isolation pitch in the gate length direction. The revision in size of the fin cut isolation compensates for overlay inaccuracy.

The gap layer is typically filled with a low stress thin film fill material that controls stresses and crack formation on the devices. Further, the gap layer ensures a certain spatial distance between TSVs and transistors to reduce the adverse effects of temperature excursion.
