摘要:
A wet-etch composition may include: peracetic acid (PAA); and a fluorinated acid; a relative amount of the PAA in the composition being sufficient to ensure an etch rate of (P-doped-SiGe):(P-doped-Si) that is substantially the same as an etch rate of (N-doped-SiGe):(N-doped-Si). Such a wet-etch composition is hereafter referred to as a PAA-based etchant and can be used to make, e.g., a CMOS MBCFET, an electrode of a capacitor, etc.

The present invention provides a method of manufacturing nano wires and nano wires having a p-n junction structure. The method includes: stacking a mask layer on a substrate; patterning the mask layer into stripes; and performing an oxygen ion injection process on the substrate and the mask layer to form oxygen ion injection regions in the substrate, thereby forming nano wire regions embedded in the substrate and separated from the substrate by the oxygen ion injection regions.

A cleaning solution includes acetic acid, an inorganic acid, a fluoride compound, and deionized water, and may further include a corrosion inhibitor, a chelating agent, or a combination thereof. The cleaning solution may be used in the formation of a metal pattern in which a metal film including ruthenium is formed on a surface of a substrate, and a portion of the metal film is dry-etched to form a metal film pattern. After dry-etching, the metal film pattern is cleaned with the cleaning solution to remove an etching by-product layer around the metal film pattern. The cleaning solution may also be used to remove an etching by-product layer around an oxide film pattern prior to dry-etching of the metal film.
