    摘要: A method for testing integrated circuits includes forming a plurality of substantially identical first test structures, each comprising a first via structure connected to a first metal line, stress testing the plurality of first test structures to obtain a first plurality of failure times, and forming a plurality of substantially identical second test structures, each comprising a second via structure connected to a second metal line, wherein the second via structure has a substantially different reliability from the first via structure, and wherein the first metal line and the second metal line are substantially identical. The method further includes stress testing the plurality of second test structures to obtain a second plurality of failure times, and determining early failures of the plurality of first test structures and the plurality of second test structures.

    摘要: A method is disclosed for depositing a Black Diamond layer in a CVD chamber. Trimethylsilane, O2, and Ar are flowed into the chamber at 300° C. to 400° C. with an O2:Ar:trimethylsilane flow rate ratio that is preferably 1:1.5:6. The resulting low k dielectric layer is formed with a higher deposition rate than when Ar is omitted and has a k value of about 3 that increases only slightly in O2 plasma. A higher density, hardness, and tensile strength are achieved in the Black Diamond layer when Ar is included in the deposition process. The addition of Ar in the deposition maintains film thickness uniformity below 2% for a longer period so that PM cleaning operations are less frequent and affords a lower fluorocarbon plasma etch rate to enable improved trench depth control in a damascene scheme. A lower leakage current and higher breakdown voltage in achieved in the resulting metal interconnect.

    摘要: A simple method for calculating the optimum amount of HDP deposited material that needs to be removed during CMP (without introducing dishing) is described. This method derives from our observation of a linear relationship between the amount of material that needs to be removed in order to achieve full planarization and a quantity called “OD for CMP density”. The latter is defined as PA×(100−PS) where PA is the percentage of active area relative to the total wafer area and PS is the percentage of sub-areas relative to the total wafer area. The sub-areas are regions in the dielectric, above the active areas, that are etched out prior to CMP. Thus, once the materials have been characterized, the optimum CMP removal thickness is readily calculated for a wide range of different circuit implementations.

    摘要翻译: 描述了一种用于计算在CMP期间需要去除的HDP沉积材料的最佳量的简单方法(不引入凹陷)。 该方法来源于我们观察到需要去除的材料的量之间的线性关系以实现完全平坦化,并且称为“用于CMP密度的OD”。 后者被定义为PAx(100-PS),其中PA是相对于总晶片面积的有效面积的百分比,PS是相对于总晶片面积的子区域的百分比。 子区域是在CMP之前被蚀刻出的有源区域之上的电介质区域。 因此,一旦材料被表征,就可以很容易地计算各种不同电路实现的最佳CMP去除厚度。
