    摘要: A metal gate structure comprises a metal layer partially filling a trench of the metal gate structure. The metal layer comprises a first metal sidewall, a second metal sidewall and a metal bottom layer. By employing an uneven protection layer during an etching back process, the thickness of the first metal sidewall is less than the thickness of the metal bottom layer and the thickness of the second metal sidewall is less than the thickness of the metal bottom layer. The thin sidewalls allow extra space for subsequent metal-fill processes.

    摘要: A method includes providing a semiconductor substrate having a gate trench and depositing a metal layer, using a physical vapor deposition (PVD) process, over the substrate to partially fill the trench. The metal layer includes a bottom portion and a sidewall portion that is thinner than the bottom portion. The method also includes forming a coating layer on the metal layer, etching back the coating layer such that a portion of the coating layer protects a portion of the metal layer within the trench, and removing the unprotected portion of the metal layer. A different aspect involves a semiconductor device that includes a gate that includes a trench having a top surface, and a metal layer formed over the trench, wherein the metal layer includes a sidewall portion and a bottom portion, and wherein the sidewall portion is thinner than the bottom portion.
