    Abstract: A method is provided for eliminating uneven heating of substrate active areas during laser thermal annealing (LTA) due to variations in gate electrode density. Embodiments include adding dummy structures, formed simultaneously with the gate electrodes, to “fill in” the spaces between isolated gate electrodes, such that the spacing between the gate electrodes and the dummy structures is the same as the spacing between the densest array of device structures on the substrate surface. Since the surface features (i.e., the gate electrodes and the dummy structures) appear substantially uniform to the LTA laser, the laser radiation is uniformly absorbed by the substrate, and the substrate surface is evenly heated.

    Abstract: Enantiomeric resolution is realized by combining an electrochemical method with ligand exchange (LE) in a novel electrochemical method named chiral ligand exchange potentiometry. Chiral selector ligands preferentially recognize certain enantiomers and undergo ligand exchange with the enantiomeric labile coordination complexes to form diastereoisomeric complexes. These complexes can form in solution and be recognized by an unmodified electrode, or they can be immobilized on the surface of a modified electrode (chiral sensor) incorporated with the chiral selector ligand by polysiloxane monolayer immobilization (PMI). Considerable stereoselectivity occurs in the formation of these diastereoisomeric complexes, and their net charges (Nernst factors) are different, thus enabling enantiomers to be distinguished by potentiometric electrodes without any pre-separation processes.

    Abstract translation: 通过将电化学方法与配体交换(LE)结合在一种称为手性配体交换电位法的新型电化学方法中来实现对映体拆分。 手性选择配体优先识别某些对映异构体并与对映异构体不稳定配位络合物进行配体交换以形成非对映异构体复合物。 这些配合物可以在溶液中形成并被未改性的电极识别,或者它们可以通过聚硅氧烷单层固定化(PMI)固定在掺入手性选择配体的改性电极(手性传感器)的表面上。 在形成这些非对映异构体复合物时会产生相当大的立体选择性,它们的净电荷(能斯特因子)是不同的,因此能够通过电位电极区分对映异构体,而无需任何预分离过程。

    Abstract: Dopant deactivation, particularly at the Si/silicide interface, is avoided by forming deep source/drain implants after forming silicide layers on the substrate and activating the source/drain regions by laser thermal annealing. Embodiments include forming source/drain extensions, forming metal silicide layers on the substrate surface and gate electrode, forming preamorphized regions under the metal silicide layers in the substrate, ion implanting to form deep source/drain implants overlapping the preamorphized regions and extending deeper into the substrate then the preamorphized regions, and laser thermal annealing to activate the deep source/drain regions.
