Some embodiments include a semiconductor construction which has one or more openings extending into a substrate. The openings are at least partially filled with dielectric material comprising silicon, oxygen and carbon. The carbon is present to a concentration within a range of from about 3 atomic percent to about 20 atomic percent. Some embodiments include a method of providing dielectric fill across a semiconductor construction having an opening extending therein. The semiconductor construction has an upper surface proximate the opening. The method includes forming photopatternable dielectric material within the opening and across the upper surface, and exposing the photopatternable dielectric material to patterned actinic radiation. Subsequently, the photopatternable dielectric material is developed to pattern the photopatternable dielectric material into a first dielectric structure which at least partially fills the opening, and to remove the photopatternable dielectric material from over the upper surface.

In order to provide a resin composition excellent in pattern processability and film strength, a resin composition film, and a semiconductor device using these, there is provided a resin composition including (A) a polymer compound, (B) a cationic polymerizable compound, and (C) a cationic polymerization initiator, in which (A) the polymer compound has a carboxylic acid residue at a molecular chain terminal.

A bisphenol A derivative, a preparation method therefor and use thereof in photolithography are provided. The compounds feature simple molecular structure, controllable molecular weight, simple synthesis steps, and relatively high thermal stability. They do not precipitate during baking and are not easily denatured during photolithography. The negative molecular glass photoresists have good film-forming property, high thermal stability, less proneness to properties varying during storage, and low viscosity, no need for additional solvents for dilution during use. After exposure at UV wavelength of 365 nm, the exposed pattern shows high contrast, excellent resolution and good sensitivity, and can present the lithographic line width of 3.5 μm.

A method for producing a lithographic printing plate uses the lithographic printing plate precursor. A polymer particle includes an addition polymerization resin having a hydrophilic structure and a crosslinking structure. A composition includes the polymer particle.

Heterocyclic-functional resins, such as epoxides, oxetanes, cyclic carbonates, lactides and lactones, are used in radiation-curable formulations along with ethylenically unsaturated materials such as (meth)acrylates to achieve improved mechanical properties and/or lower shrinkage in the cured compositions prepared therefrom as compared to formulations containing the ethylenically unsaturated materials but no heterocyclic-functional resin. Polymerizable, ethylenically unsaturated metal complexes, such as Zn and Ca carboxylates prepared using unsaturated carboxylic acids or anhydrides, may be employed to effect thermal cure of the heterocyclic-functional resin component of such formulations, which are particularly useful in the production of 3D-printed articles and the like.
