    • Disclose are embodiments of an integrated circuit design method based on a combination of manufacturability, test coverage and, optionally, diagnostic coverage. Design-for manufacturability (DFM) modifications to the layout of an integrated circuit can be made in light of test coverage. Alternatively, test coverage of an integrated circuit can be established in light of DFM modifications. Alternatively, an iterative process can be performed, where DFM modifications to the layout of an integrated circuit are made in light of test coverage and then test coverage is altered in light of the DFM modifications. Alternatively, DFM modifications to the layout of an integrated circuit can be made in light of test coverage and also diagnostic coverage. In any case, after making DFM modifications and establishing test coverage, any unmodified and untested nodes (and, optionally, any unmodified and undiagnosable tested nodes) in the integrated circuit can be identified and tagged for subsequent in-line inspection.
    • 披露是基于可制造性,测试覆盖和任选的诊断覆盖的组合的集成电路设计方法的实施例。 根据测试覆盖范围,可以对集成电路布局的可制造性(DFM)进行设计修改。 或者,可以根据DFM修改建立集成电路的测试覆盖。 或者,可以执行迭代处理,其中根据测试覆盖进行DFM对集成电路的布局的修改,然后根据DFM修改来改变测试覆盖。 或者,DFM可以根据测试覆盖范围和诊断覆盖范围对集成电路布局进行修改。 在任何情况下,在进行DFM修改和建立测试覆盖之后,可以识别和标记集成电路中的任何未修改和未测试的节点(以及可选地,任何未修改和不可判定的测试节点)以便随后的在线检查。

    • Disclosed is a method of manufacturing dual orientation wafers. A trench is formed in a multi-layer wafer to a silicon substrate with a first crystalline orientation. The trench is filled with a silicon material (e.g., amorphous silicon or polysilicon trench). Isolation structures are formed to isolate the silicon material in the trench from a semiconductor layer with a second crystalline orientation. Additional isolation structures are formed within the silicon material in the trench and within the semiconductor layer. A patterned amorphization process is performed on the silicon material in the trench and followed by a recrystallization anneal such that the silicon material in the trench recrystallizes with the same crystalline orientation as the silicon substrate. The resulting structure is a semiconductor wafer with isolated semiconductor areas on the same plane having different crystalline orientations as well as isolated sections within each semiconductor area for device formation.
    • 公开了制造双取向晶片的方法。 在多层晶片中形成具有第一晶体取向的硅衬底的沟槽。 沟槽填充有硅材料(例如,非晶硅或多晶硅沟槽)。 形成隔离结构以将沟槽中的硅材料与具有第二晶体取向的半导体层隔离。 另外的隔离结构形成在沟槽内和半导体层内的硅材料内。 对沟槽中的硅材料进行图案化非晶化处理,然后进行再结晶退火,使得沟槽中的硅材料以与硅衬底相同的结晶取向重结晶。 所得到的结构是在具有不同晶体取向的同一平面上的隔离半导体区域以及用于器件形成的每个半导体区域内的隔离部分的半导体晶片。
