PL-1 (56) and part (341) of the semiconductor layer (34) are etched to form a device mesa (35). A second passivation layer (PL-2) (59) is formed over PL-1 (56) and exposed edges (44) of the mesa (35). Vias (90, 92, 93) are etched through PL-1 (56) and PL-2 (59) to the semiconductor layer (34) where source (40), drain (42) and gate are formed. Conductors (41, 43, 39) are applied in the vias (90, 92, 93). Interconnections (45, 47) over the edges (44) of the mesa (35) couple other circuit elements. PL-1 (56) avoids adverse surface states (52) near the gate and PL-2 (59) insulates edges (44) of the mesa (35) from overlying interconnections (45, 47) to avoid leakage currents (46). An opaque alignment mark (68) is desirably formed to facilitate alignment when using transparent semiconductors (34).

PL-I (56) and part (341) of the semiconductor layer (34) are etched to form a device mesa (35). A second passivation layer (PL-2) (59) is formed over PL-I (56) and exposed edges (44) of the mesa (35).

Interconnections (45, 47) over the edges (44) of the mesa (35) couple other circuit elements. PL-I (56) avoids adverse surface states (52) near the gate and PL-2 (59) insulates edges (44) of the mesa (35) from overlying interconnections (45, 47) to avoid leakage currents (46).

    • Performance measurement targets are used to measure performance of a lithographic process after processing a number of substrates. In a set-up phase, the method selects an alignment mark type and alignment recipe from among a plurality of candidate mark types by reference to expected parameters of the patterning process. After exposing a number of test substrates using the patterning process, a preferred metrology target type and metrology recipe are selected by comparing measured performance (e.g. overlay) of performance of the patterning process measured by a reference technique. Based on the measurements of position measurement marks and performance measurement targets after actual performance of the patterning process, the alignment mark type and/or recipe may be revised, thereby co-optimizing of the alignment marks and metrology targets. Alternative run-to-run feedback strategies may also be compared during subsequent operation of the process.
    • 性能测量目标用于在处理多个衬底之后测量光刻工艺的性能。 在设置阶段,该方法通过参考构图过程的预期参数从多个候选标记类型中选择对准标记类型和对准配方。 在使用图案化工艺曝光多个测试衬底之后,通过比较由参考技术测量的图案化工艺的性能的测量性能(例如,重叠)来选择优选的度量目标类型和度量配方。 基于在图案化过程的实际执行之后对位置测量标记和性能测量目标的测量结果,可以修改对准标记类型和/或配方,从而共同优化对准标记和度量目标。 另外的运行反馈策略也可以在流程的后续操作中进行比较。
