    • A method of testing a semiconductor wafer and a related structure. In various embodiments, a method includes: placing a probe on a first chip on the semiconductor wafer; testing a scribe line automatic built-in self-test (ABIST) for the first chip to search for a fault; progressively testing a subsequent scribe line ABIST for a subsequent chip on the semiconductor wafer in response to determining the ABIST for the first chip does not indicate the fault; moving the probe point to the subsequent chip and retesting the subsequent scribe line ABIST in response to determining the ABIST for the subsequent chip indicates a fault; and testing a further subsequent scribe line ABIST for a further subsequent chip on the semiconductor wafer in response to determining the retesting of the subsequent scribiline ABIST does not indicate a fault in the subsequent scribe line ABIST.

    • A method for forming a plurality of variable linewidth spacers adjoining a plurality of uniformly spaced topographic features uses a conformal resist layer upon a spacer material layer located over the plurality of uniformly spaced topographic features. The conformal resist layer is differentially exposed and developed to provide a differential thickness resist layer that is used as a sacrificial mask when forming the variable linewidth spacers. A method for forming uniform linewidth spacers adjoining narrowly spaced topographic features and widely spaced topographic features over the same substrate uses a masked isotropic etching of a variable thickness spacer material layer to provide a more uniform partially etched spacer material layer, followed by an unmasked anisotropic etching of the partially etched spacer material layer. A related method for forming the uniform linewidth spacers uses a two-step anisotropic etch method that includes at least one masking process step.
    • 用于形成邻接多个均匀间隔的地形特征的多个可变线宽间隔物的方法在位于多个均匀间隔的地形特征之上的间隔物材料层上使用共形抗蚀剂层。 保形抗蚀剂层被差异地曝光和显影以提供在形成可变线宽间隔物时用作牺牲掩模的差分厚度抗蚀剂层。 用于形成均匀线宽间隔物的方法,其邻接狭窄间隔的地形特征和在相同基底上的宽间隔的地形特征,使用可变厚度间隔物材料层的掩蔽各向同性蚀刻,以提供更均匀的部分蚀刻的间隔物材料层,随后是未掩模的各向异性蚀刻 的部分蚀刻的间隔材料层。 用于形成均匀线宽间隔物的相关方法使用包括至少一个掩模处理步骤的两步各向异性蚀刻方法。
