摘要： It is disclosed a method of forming fine patterns comprising repeating plural times the following course of steps: covering a substrate having thereon photoresist patterns with an over-coating agent for forming fine patterns, applying heat treatment to cause thermal shrinkage of the over-coating agent so that the spacing between the adjacent photoresist patterns is lessened by the resulting thermal shrinking action, and removing the over-coating agent. The invention provides a method of forming fine patterns which has high ability to control pattern dimensions and provide fine patterns that have a satisfactory profile and satisfy the characteristics required of semiconductor devices, even in the case of employing a substrate having thick-film photoresist patterns in a thickness of about 1.0 μm or more.

摘要： 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.

Also disclosed is a method of forming fine-line patterns using the over-coating agent. The advantages of the invention are that the exposure margin is large, that the dimension control of photoresist patterns can be reflected on the dimension controllability in forming fine-line patterns, that the dimension control and planning of forming fine trace patterns after treatment for thermal shrinkage can be attained with ease in the stage of photoresist patterning, that the original photoresist pattern profile can be kept as such and the top of the photoresist pattern is not rounded after thermal shrinkage, that the degree of thermal shrinkage of the over-coating agent is large and thus the agent is effective in forming fine-line patterns.
