    摘要: A test cell for localizing defects includes a first active region, a second active region formed substantially parallel to the first active region, a third active region formed substantially parallel to the first and second active regions, a fourth active region formed between the first and second active regions, and a fifth active region formed between the second and third active regions. The fourth and fifth active regions are formed adjacent to opposite end portions of the second active region. The fourth and fifth active regions are also formed substantially perpendicular to the second active region.

    摘要: A system and method for predicting yield of integrated circuits includes at least one type of characterization vehicle which incorporates at least one feature which is representative of at least one type of feature to be incorporated in the final integrated circuit product. The characterization vehicle is subjected to at least one of the process operations making up the fabrication cycle to be used in fabricating the integrated circuit product in order to produce a yield model. The yield model embodies a layout as defined by the characterization vehicle and preferably includes features which facilitate the gathering of electrical test data and testing of prototype sections at operating speeds. An extraction engine extracts predetermined layout attributes from a proposed product layout. Operating on the yield model, the extraction engine produces yield predictions as a function of layout attributes and broken down by layers or steps in the fabrication process. These yield predictions are then used to determine which areas in the fabrication process require the most improvement.

    摘要: A test vehicle (100) comprises a substrate (99), a plurality of nested serpentine lines (202) on the substrate, and a plurality of test pads (204) on the substrate. Each serpentine line has a plurality of turn sections that comprise two parallel line segments connected by a perpendicular line segment. Each of the plurality of test pads is connected to a respective turn section of a respective one of the nested serpentine lines. Each pair of test pads connected to one of the subset of the nested serpentine lines has at least a respectively different turn section portion connected therebetween.

    摘要: A test structure comprising a test pattern is formed on a substrate. The test pattern includes a first comb structure having a plurality of tines, and a second structure. The second structure may be a snake structure having a plurality of side walls or a second comb structure having a plurality of side walls. The tines of the first comb structure are positioned within side walls of the snake structure or second comb structure. The tines of the first comb structure are offset from a center of the side walls. Test data collected from the test structure are analyzed, to estimate product yield. The test structure may have a lower layer pattern, such that topographical variations of the lower layer pattern propagate to an upper layer pattern of the test structure.
