摘要:
A novel process is provided for the preparation of pyrrolidine carboxylic acids, and the useful intermediates obtained therein. These compounds are intermediates for the synthesis of melanocortin-4 receptor (MC-4R), which are useful for the treatment of disorders such as obesity, diabetes, sexual dysfunction, male sexual dysfunction, and female sexual dysfunction.
摘要:
A system and method for identifying misalignments in an overlapping region of a stitched circuit in an integrated circuit fabrication process. The method comprises: creating a first circuit using a reference mask, wherein first circuit includes a first part of an offset dependent resistor structure in the overlapping region; creating a second circuit using a secondary mask, wherein the second circuit includes a second part of the offset dependent resistor structure in the overlapping region, wherein the offset dependent resistor structure includes a plurality of nubs that interconnect the first part and the second part of theis offset dependent resistor structure; measuring a resistance across the offset dependent resistor structure; and determining an amount of misalignment based on the measured resistance.
摘要:
An apparatus and method for matched variable resistor structures to electrically measure unidirectional misalignment of stitched masks for etched interconnect layers includes a first test pad (101) and a second test pad (102) for measuring resistance therebetween; a first resistive element (105) electrically connected at a first end to the first test pad (101); and, a second resistive element (110) electrically connected at a first end to the second test pad (102). The first resistive element and the second resistive element are electrically connected by a vertical offset (112). The resistance measured between the first test pad and the second test pad is variable in accordance with an alignment of the first resistive element and the second resistive element relative to the vertical offset, see FIG. 1C-E. An indicator may optionally provide an indication that the resistive elements are in alignment.
