Abstract:
In a method forming patterns, a layer on a substrate is patterned by a first etching process using an etch mask to form a plurality of first preliminary patterns and a plurality of second preliminary patterns. The second preliminary patterns are spaced apart from each other at a second distance larger than a first distance at which the first preliminary patterns are spaced apart. First and second coating layers are formed on sidewalls of the first and second preliminary patterns, respectively, and the first and second coating layers and portions of the first and second preliminary patterns are removed by a second etching process using the etch mask to form a plurality of first patterns and a plurality of second patterns. The first patterns have widths that are smaller than widths of the first preliminary patterns. The first patterns may have generally vertical sidewalls relative to the substrate.
Abstract:
A method of fabricating an integrated circuit device includes forming a plurality of lower capacitor electrodes vertically extending from a substrate. The plurality of lower capacitor electrodes respectively include an inner sidewall and an outer sidewall. At least one support pattern is formed vertically extending between ones of the plurality of lower capacitor electrodes from top portions thereof opposite the substrate and along the outer sidewalls thereof towards the substrate to a depth that is greater than a lateral distance between adjacent ones of the plurality of lower capacitor electrodes. A dielectric layer is formed on the support pattern and on outer sidewalls of the plurality of lower capacitor electrodes, and an upper capacitor electrode is formed on the dielectric layer. Related devices are also discussed.
Abstract:
An electronic device may include a substrate, and a plurality of spaced apart pads on the substrate. Each of the pads may includes first, second, third, and fourth sides, the first and third sides may be opposite sides that are substantially straight, and the second and fourth sides may be opposite sides that are curved. Related methods, devices, and structures are also discussed.
