Abstract:
A process for depositing a layer of product on at least part of a major surface of a substrate having two sides separated by a thickness of less than about 3 mm is provided. The process involves using an immersion technique, in which the substrate is placed in a liquid medium containing a solution or dispersion of the product to be deposited or one of its precursors; removed from the liquid medium such that the substrate is coated with a liquid layer, and at least part of the liquid medium contained in the deposited liquid layer is evaporated, wherein the process is characterized as being carried out under conditions in which cooling of the substrate as a result of evaporation of said part of the liquid medium is limited An advantageous variant of the process involves in heating the immersion bath to a temperature that is sufficient to at least partially compensate for substrate cooling resulting from evaporation of the liquid medium. The inventive process can be used advantageously for depositing a solid layer by means of a sol-gel type process.

Abstract:
It is disclosed an over-coating agent for forming fine-line patterns which is applied to cover a substrate having thereon photoresist patterns and allowed to shrink under heat so that the spacing between adjacent photoresist patterns is lessened, with the applied film of the over-coating agent being removed substantially completely to form or define fine trace patterns, further characterized by containing a copolymer or a mixture of polyvinyl alcohol with a water-soluble polymer other than polyvinyl alcohol. Also disclosed is a method of forming fine-line patterns using the over-coating agent. According to the invention, one can effectively increase the shrinkage amount (the amount of heat shrinking) of the agent, thereby achieving a remarkably improved effect of forming or defining fine-line patterns and which also present satisfactory profiles and meet the characteristics required of today's semiconductor devices.
