    • A semiconductor process exposes metal in anticipation of an additional processing step that includes a deposition of a layer. Between the two processing steps, the exposed metal is exposed to ambient conditions that may include humidity. The effect of the humidity is potentially to cause corrosion of the exposed metal causing a yield loss. In order to withstand the various time periods that may occur between processing steps, an inhibitor is applied to the exposed surface causing the formation of a very thin protective layer on the exposed metal, which greatly inhibits corrosion. This thin protective layer does not cause any problems with the subsequent step because the typical following steps all, by their very nature, remove the protective layer. Thus, the time period between the processing step that exposes the metal and the next step is no longer critical due to the protective layer.
    • 半导体工艺在预期包括层的沉积的附加处理步骤的情况下暴露金属。 在两个处理步骤之间,暴露的金属暴露于可能包括湿度的环境条件下。 湿度的影响可能导致暴露金属的腐蚀,导致产量损失。 为了承受处理步骤之间可能发生的各种时间段,将抑制剂施加到暴露的表面,导致在暴露的金属上形成非常薄的保护层,这极大地抑制了腐蚀。 这个薄的保护层不会对随后的步骤造成任何问题,因为典型的后续步骤全部由它们的本质来去除保护层。 因此,由于保护层,暴露金属的处理步骤和下一步骤之间的时间段不再是关键的。

    • A method for depositing a first metal layer such as tantalum or copper on a patterned semiconductor wafer using a metal sputtering tool that typically includes an electrically biased wafer chuck is disclosed. Initially, a first test wafer is placed on the wafer chuck and a first test layer of materials is deposited on the first test wafer. During the deposition of the first test layer on the first test wafer, the wafer receives the electrical bias at a first level. A second test wafer is then placed on the wafer chuck and a second test layer of material is deposited with the second wafer receiving a second level of electrical bias. The difference in thickness between the first layer and the second layer is then determined. If the difference in thickness is within a predetermined range, the metal sputtering chamber is qualified to deposit a production layer on a production semiconductor wafer.
    • 公开了一种使用通常包括电偏置晶片卡盘的金属溅射工具在图案化半导体晶片上沉积诸如钽或铜的第一金属层的方法。 首先,将第一测试晶片放置在晶片卡盘上,并将第一测试层材料沉积在第一测试晶片上。 在将第一测试层沉积在第一测试晶片上时,晶片在第一级接收电偏压。 然后将第二测试晶片放置在晶片卡盘上,并且第二测试层材料沉积,第二晶片接收第二级电偏压。 然后确定第一层和第二层之间的厚度差。 如果厚度差在预定范围内,则金属溅射室有资格在生产半导体晶片上沉积生产层。
