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.

  • Publication number: 20190019720
    Abstract: Some embodiments include a construction having a horizontally-extending layer of fluorocarbon material over a semiconductor construction. Some embodiments include methods of filling openings that extend into a semiconductor construction. The methods may include, for example, printing the material into the openings or pressing the material into the openings. The construction may be treated so that surfaces within the openings adhere the material provided within the openings while surfaces external of the openings do not adhere the material. In some embodiments, the surfaces external of the openings are treated to reduce adhesion of the material.

  • Publication number: 20130313718
    Abstract: A method of processing a substrate having integrated circuitry includes forming through-substrate vias partially through the substrate from a first side of the substrate. At least one through-substrate structure is formed partially through the substrate from the first substrate side. The at least one through-substrate structure extends deeper into the substrate than do the through-substrate vias. Substrate material is removed from a second side of the substrate to expose the through-substrate vias and the at least one through-substrate structure on the second substrate side. Additional implementations are disclosed. Integrated circuit substrates are disclosed independent of method of manufacture.

  • Publication number: 20130095655
    Abstract: A method of forming circuit structures within openings includes forming pairs of spaced projections that project elevationally relative to a support material on opposing sides of respective openings formed into the support material. At least two of the spaced projections of different of the pairs are received between immediately adjacent of the openings. Conductive metal is formed elevationally over the projections and into and overfilling the openings. The metal is of a composition different from that of at least elevationally outermost portions of the projections. The metal is removed from being elevationally over the projections and at least some of the metal between the projections is removed. Other embodiments and aspects are disclosed.
