摘要： A method includes forming a layer of molecular feedstock over a surface of a substrate, the molecular feedstock including a chiral molecule, forming crystal nuclei from the molecular feedstock within a nucleation region of the layer, and growing the crystal nuclei to form an organic solid crystal (OSC) thin film. A chiral molecule-containing organic solid crystal thin film may have a refractive index and birefringence that can be actively tuned via charge injection. An organic solid crystal (OSC) thin film including a single enantiomer of a chiral organic molecule may be configured to propagate a selected handedness of circularly polarized light.

摘要： A block copolymer, adapted to self-assemble to form an ordered pattern on a substrate, has first and second blocks with a terminal moiety covalently bonded to the end of the first block. The molecular weight of the terminal moiety is 20% or less than that of the block copolymer and the terminal moiety has a low chemical affinity for the first block. The terminal moiety can assist the accurate positional placement of the domains of the ordered array and lead to improved critical dimension uniformity and/or reduced line edge roughness. The polymer may be useful in combination with a graphoepitaxy template, where the terminal moiety is chosen to associate with a sidewall of the template. This may reduce undesired aggregation of polymer domains at a sidewall and/or assist in domain placement accuracy.

摘要： A method for slicing a shaped silicon ingot includes providing a single crystal silicon boule characterized by a cropped structure including a first end-face, a second end-face, and a length along an axis in an crystallographic direction substantially vertically extending from the first end-face to the second end-face. The method further includes cutting the single crystal silicon boule substantially through an {110} crystallographic plane in parallel to the axis to separate the single crystal silicon boule into a first portion with a first surface and a second portion with a second surface. Additionally, the method includes exposing either the first surface of the first portion or the second surface of the second portion and performing a layer transfer process to form a single crystal silicon sheet from either the first surface of the first portion or from the second surface of the second portion.
