TL;DR: A non-contact alignment process, which uses low-energy ion beams impinging at a glancing angle on amorphous inorganic films, such as diamond-like carbon, is reported, and it is found that displays of higher quality and reliability could be made at a lower cost than the rubbing technique.

TL;DR: A carrier structure and method for fabricating a carrier structure with through-vias each having a conductive structure with an effective coefficient of thermal expansion which is less than or closely matched to that of the substrate, and having an effective elastic modulus value which is more than or close to the substrate.
Journal ArticleDOI
Polarization Effects of Fluorine on the Relative Permittivity in Polyimides
TL;DR: In this paper, the effect of fluorine incorporation on dielectric properties has been studied for a series of polyimides in order to distinguish between several contributing mechanisms to the generally observed decrease in the relative permittivity using low-frequency capacitance measurements after exhaustive in situ drying, in conjunction with refractive index measurements.
Journal ArticleDOI
Influence of Free Volume Change on the Relative Permittivity and Refractive Index in Fluoropolyimides
TL;DR: In this article, the authors tried to assign the observed decreases between these mechanisms for a series of hydrogen/fluorine polyimide analogs, and found that both of these effects can independently decrease the relative permittivity and refractive index.
Journal ArticleDOI
Synthesis and properties of highly fluorinated polyimides
TL;DR: A series of polyimides was synthesized to facilitate the study of several structure/property relationships, including relative permittivity, moisture absorption, free volume, and viscoelastic transitions as mentioned in this paper.
