    • A method for improving metal defects in fabricating a semiconductor device is provided to deposit thick layers without defects by dividing a metal layer into separated layers and forming a stress compensation layer between the separated layers. A metal layer(115) is deposited on a semiconductor substrate and has a thickness of about 1 micron or greater. A first portion of the metal layer is deposited on the semiconductor substrate wherein the first portion has a compressive or tensile stress. A stress compensation layer(120) is disposed on the first portion and has an opposite stress to the compressive or tensile stress related with the first portion. A second portion of the metal layer is deposited on the stress compensation layer. The stress compensation layer includes titanium, tantalum, titanium nitride, tantalum nitride or a composition thereof, and the metal layer is aluminum, copper, gold, silver, platinum or a composition thereof.
    • 提供了一种用于改善制造半导体器件中的金属缺陷的方法,通过将金属层划分成分离的层并在分离的层之间形成应力补偿层来沉积没有缺陷的厚层。 金属层(115)沉积在半导体衬底上并具有约1微米或更大的厚度。 金属层的第一部分沉积在半导体衬底上,其中第一部分具有压缩或拉伸应力。 应力补偿层(120)设置在第一部分上并对与第一部分相关的压缩或拉伸应力具有相反的应力。 金属层的第二部分沉积在应力补偿层上。 应力补偿层包括钛,钽,氮化钛,氮化钽或其组合物,金属层是铝,铜,金,银,铂或其组合物。
