    摘要: A method for modulating stress in films formed in semiconductor device manufacturing provides for high temperature annealing of an as-deposited compressive film such as titanium nitride. The high temperature annealing converts the initially compressive film to a tensile film without compromising other film qualities and characteristics. The converted tensile films are particularly advantageous as work function adjusting films in PMOS transistor devices and are advantageously used in conjunction with additional metal gate materials.

    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.
