Abstract: There is described a method of chemically depositing a substance. The method is of utility in the direct manufacture of integrated circuits and in the manufacture of a photomask for use in production of integrated circuits. The method involves the use of a compound which degrades into a deposit and a residue when a radiant beam (e.g., a laser beam) or a particle beam (e.g., an electron beam) is applied. The residue and any unreacted compound may be washed off the substrate to which it has been applied. Nanoscale dimensions of the deposit can be achieved. A particularly suitable organometallic compound is tetra-sec butyl diaurum difluoride.

Abstract: The invention is concerned with providing substrates with coatings obtainable from sols, for example to protect the substrate (such as in nuclear reactors or hydrocarbon cracking plant) or to provide a carrier for catalytically active material.Hitherto, coatings obtained from sols have had a high porosity and high surface area so that they have not been entirely satisfactory for the above applications.In the invention, dense, low-porosity coatings are provided by contacting the substrate with a sol of refractory material (e.g. CeO.sub.2 or SiO.sub.2) convertible to a gel of density at least 40% of the theoretical density of the refractory material, and converting the sol to the gel. Optionally, the gel may be converted to a ceramic coating by firing.
