    Abstract: An improved method for fabricating a semiconductor device is provided to decrease substrate gouging during oxide spacer formation. The method includes: forming a gate structure on a substrate; depositing an oxide layer along the sidewalls of the gate structure and on the substrate; removing some of the oxide layer to define oxide spacers along sidewalls of the gate structure; and performing an isotropic etch process to remove a residual portion of the oxide layer.

    Abstract: The present disclosure relates to semiconductor structures and, more particularly, to methods to remove a contact etch stop layer without consuming material of a self-aligned contact (SAC) layer. The method includes: forming a gate structure on a substrate; forming a capping layer on the gate structure; forming a contact etch stop layer of a first material, adjacent to the gate metal structure; converting the contact etch stop layer to a second material which is different than the capping layer; and selectively removing the second material without completely removing the capping layer.

    Abstract: Devices and methods of fabricating integrated circuit devices with reduced cell height are provided. One method includes, for instance: obtaining an intermediate semiconductor device having a substrate including a logic area and an SRAM area, a fin material layer, and a hardmask layer; depositing a mandrel over the logic area; depositing a sacrificial spacer layer; etching the sacrificial spacer layer to define a sacrificial set of vertical spacers; etching the hardmask layer; leaving a set of vertical hardmask spacers; depositing a first spacer layer; etching the first spacer layer to define a first set of vertical spacers over the logic area; depositing an SOH layer; etching an opening in the SOH layer over the SRAM area; depositing a second spacer layer; and etching the second spacer layer to define a second set of spacers over the SRAM area.
