摘要: A composition for forming an organic film contains a polymer having a partial structure shown by the following general formula (1) as a repeating unit, and an organic solvent. Each of AR1 and AR2 represents a benzene ring or naphthalene ring which optionally have a substituent; W1 represents a particular partial structure having a triple bond, and the polymer optionally contains two or more kinds of W1; and W2 represents a divalent organic group having 6 to 80 carbon atoms and at least one aromatic ring. This invention provides: a polymer curable even under film formation conditions in an inert gas and capable of forming an organic film which has not only excellent heat resistance and properties of filling and planarizing a pattern formed in a substrate, but also favorable film formability onto a substrate with less sublimation product; and a composition for forming an organic film, containing the polymer.

摘要: A method of coating a structure is disclosed. Method steps include providing a structure having a first portion of a first material having a first surface and providing a second portion of a second material having a second surface, wherein a mask is provided over the first surface. Another step includes exposing the mask and the second surface to a solution comprising a polymer and a solvent, wherein the solution dewets from the mask and the polymer collects onto the second surface to form a polymer coating over the second surface without forming a polymer coating on the first surface.

摘要: Various embodiments described herein relate to methods, apparatus, and systems for treating metal-containing photoresist to modify material properties of the photoresist. For instance, the techniques herein may involve providing a substrate in a process chamber, where the substrate includes a photoresist layer over a substrate layer, and where the photoresist includes metal, and treating the photoresist to modify material properties of the photoresist such that etch selectivity in a subsequent post-exposure dry development process is increased. In various embodiments, the treatment may involve exposing the substrate to elevated temperatures and/or to a remote plasma. One or more process conditions such as temperature, pressure, ambient gas chemistry, gas flow/ratio, and moisture may be controlled during treatment to tune the material properties as desired.
