Manufacturing of coated items

A method for manufacturing a coated interlaced substrate in a chemical deposition reactor, comprising:

• obtaining a chemical deposition reactor with a reaction space formed by a reaction chamber and configured to receive, at least in part, a substrate holder made of a fluid-permeable material, onto which an interlaced substrate is mounted such that a first surface of the substrate faces the reaction space, and a second surface of the substrate is placed against the substrate holder, and
• in a number of deposition cycles, forming a first coating on the first surface and/or forming a second coating on the second surface,
• wherein, each deposition cycle comprises delivering, with a flow of fluid, a precursor chemical into the reaction space such that delivery of at least one precursor chemical into the reaction space occurs via said fluid-permeable material.
