Abstract: A method for manufacturing a play-of-color article includes the steps of: (a) providing a first mixture that contains a solvent and a plurality of functionalized colloidal particles; (b) replacing the solvent of the first mixture with a polymer solution that contains polymers, thereby obtaining a second mixture; (c) adding an initiator to the second mixture to obtain a third mixture, followed by injecting the third mixture into a mold and disturbing the third mixture, so that the third mixture is formed with a pattern; (d) leaving the third mixture to stand, so as to allow the functionalized colloidal particles therein to self-assemble to form a crystalline arrangement, thereby obtaining a fourth mixture; and (e) subjecting the polymers in the fourth mixture to a cross-linking reaction, thereby obtaining the play-of-color article. A play-of-color article manufactured by the method, and a play-of-color product including the play-of-color article are also provided.

Abstract: Various solutions for tiered channel information feedback with respect to user equipment and network apparatus in mobile communications are described. An apparatus may determine a first tier channel state information (CSI) based on a first reference signal resource measurement. The apparatus may report the first tier CSI to a network node. The apparatus may determine a second tier CSI based on the first tier CSI and based on a second reference signal resource measurement. The apparatus may report the second tier CSI to the network node. The second tier CSI may be different from the first tier CSI.

Abstract: In an embodiment, a device includes: a first semiconductor nanostructure; a second semiconductor nanostructure adjacent the first semiconductor nanostructure; a first source/drain region on a first sidewall of the first semiconductor nanostructure; a second source/drain region on a second sidewall of the second semiconductor nanostructure, the second source/drain region completely separated from the first source/drain region; and a source/drain contact between the first source/drain region and the second source/drain region.

Abstract: A method and an apparatus are provided for removing a mobile ion in a wafer. The apparatus includes a first inlet for providing a first reactant, a reaction region for generating an active substance with a charge from the first reactant, and a susceptor electrically connected to a voltage for disposing the wafer thereon to attract the active substance to a surface of the wafer and repulsing the mobile ion to the surface of the wafer to enable the mobile ion to react with the active substance to produce a material separable from the wafer.

Abstract: An in situ inter-dielectric process is disclosed for forming multilevel metal structures. The process includes the steps of:(1) forming an SOG layer on an uneven semiconductor surface,(2) treating a surface of the SOG layer with a plasma in a PECVD chamber, and(3) forming a PECVD oxide layer on the treated surface in the same PECVD chamber.The operating parameters for performing the in situ treatment are as follows:______________________________________ Gas: N.sub.2 O or C.sub.2 F.sub.6 Pressure: 4-6 Torr Temperature: 300-400.degree. C. Power: 200-400 Watts Gap: 300-800 mil Flow: 500-1500 sccm Time: 5-15 sec ______________________________________Thus, the treatment can be performed in the same PECVD chamber used to form a PECVD oxide layer on the treated SOG layer.Furthermore, the SOG layer surface may be oxidized to produce an organic deficient SiO.sub.x layer at the surface of the SOG layer prior to performing the treatment step (2).
