摘要： A structure, and method of forming and cooling the structure. The structure may include a substrate (e.g., a semiconductor chip) having N continuous substrate channels and an interposer having N continuous interposer channels (N≧2). The N interposer channels are coupled to the N substrate channels to form M continuous loops (1≦M≦N). The M loops may transfer heat from a heat source within the substrate to the interposer and then to a heat sink thermally coupled to the interposer. The structure may include an interposer having a thermally conductive enclosure surrounding a cavity. The cavity contains a thermally conductive foam material (e.g., graphite foam). The foam material contains a serpentine channel having contiguously connected channel segments. The serpentine channel may transfer heat from a heat source within a substrate (e.g., a semiconductor chip) to the interposer and then to a heat sink thermally coupled to the interposer.

摘要： A liquid crystal (LC) lightvalve comprising a twisted nematic LC layer whose molecules are aligned with pixel edges at the mirror backplane, thereby providing improved contrast and efficiency, and reduced visibility of post spacers in black state. The present invention is directed to an LC structure wherein the backplane is rubbed in a direction rectilinear with pixel edges. The LC layer is given the same twist rotation and birefringence as in the conventional TN lightvalve. Polarization control is maintained by illuminating the lightvalve with light whose polarization is rotated by the twist angle relative to the x,y, pixel axes, and by collecting the orthogonally polarized component of the reflected light. The lightvalve top glass is thus rubbed in a direction which is rotated by the twist angle from the horizontal or vertical direction at which the backplane is rubbed.
