    • A method and precursor for forming and integrating a Ta-containing layer in semiconductor processing. The tantalum precursor has the formula (CpR1)(CpR2)TaH(CO), where Cp is a cyclopentadienyl functional group and R1 and R2 are H or alkyl groups. The method includes providing a substrate in a process chamber of a deposition system, and exposing a process gas comprising the tantalum precursor to the substrate to form the Ta-containing layer. The Ta-containing layer may be treated to remove contaminants and modify the layer. The Ta-containing layer may contain tantalum metal, tantalum carbide, tantalum nitride, or tantalum carbonitride, or a combination thereof, and may be deposited in a TCVD, ALD, or PEALD process. A semiconductor device containing a Ta-containing layer formed on a patterned substrate containing one or more vias or trenches is provided.
    • 用于在半导体加工中形成和集成含Ta层的方法和前体。 钽前体具有式(CpR1)(CpR2)TaH(CO),其中Cp是环戊二烯基官能团,R1和R2是H或烷基。 该方法包括在沉积系统的处理室中提供衬底,并且将包含钽前体的处理气体暴露于衬底以形成含钽层。 含钽层可被处理以去除污染物并改变层。 含Ta层可以含有钽金属,碳化钽,氮化钽或碳氮化钽或其组合,并且可以以TCVD,ALD或PEALD工艺沉积。 提供了包含形成在包含一个或多个通孔或沟槽的图案化衬底上的含Ta层的半导体器件。
