Pattern decomposition lithography techniques

Techniques are disclosed for realizing a two-dimensional target lithography feature/pattern by decomposing (splitting) it into multiple unidirectional target features that, when aggregated, substantially (e.g., fully) represent the original target feature without leaving an unrepresented remainder (e.g., a whole-number quantity of unidirectional target features). The unidirectional target features may be arbitrarily grouped such that, within a grouping, all unidirectional target features share a common target width value. Where multiple such groupings are provided, individual groupings may or may not have the same common target width value. In some cases, a series of reticles is provided, each reticle having a mask pattern correlating to a grouping of unidirectional target features. Exposure of a photoresist material via the aggregated series of reticles substantially (e.g., fully) produces the original target feature/pattern. The pattern decomposition techniques may be integrated into any number of patterning processes, such as litho-freeze-litho-etch and litho-etch-litho-etch patterning processes.

Method of using chemically patterned guide layers in chemoepitaxy directing of block co-polymers
10366887 · 2019-07-30 · ·

The present invention is broadly concerned with materials, processes, and structures that allow an underlayer to be imaged directly using conventional lithography, thus avoiding the photoresist processing steps required by prior art directed self-assembly (DSA) processes. The underlayers can be tailored to favor a selected block of the DSA block co-polymers (BCP), depending on the pattern, and can be formulated either to initially be neutral to the BCP and switch to non-neutral after photoexposure, or can initially be non-neutral to the BCP and switch to neutral after exposure. These materials allow fast crosslinking to achieve solvent resistance and possess good thermal stability.

METHOD FOR PROCESSING SUBSTRATE

A substrate on which a processing film made of a directed self-assembly material is formed is placed on a holding plate incorporating a preheating mechanism, and is preheated. A low oxygen atmosphere surrounds the substrate. A preheating temperature is a temperature at which the directed self-assembly material comprised of two types of polymers is phase-separated. By preheating the processing film, the two types of polymers are phase-separated to form a fine pattern. The processing film is irradiated with flashes of light from flash lamps while being preheated. This increases the fluidity of the polymers constituting the processing film to achieve the formation of a fine pattern while suppressing the occurrence of defects.

PATTERNING BASED ON IN-SITU FORMATION OF BLOCK COPOYLMER THROUGH DEPROTECTION

In-situ formation of a block copolymer through deprotection can provide patterns with flexible pitches. A layer of a protected polymer including a protecting group is formed. One or more portions of the layer may be exposed to light. The exposed portion(s) may be baked after the light exposure. The protecting group is removed after the light exposure or bake so that the protected polymer becomes a deprotected polymer in the exposure portion(s). The deprotected polymer is bonded with the protected polymer in the unexposed portion(s) of the layer but has a different solubility from the protected polymer so that phases of the block copolymer are separated. The phase separation can provide a periodic pattern with various pitches. The solution and roughness of the pattern can be enhanced by using CARs formed with a protected, cross-linked polymer that includes a protective group and a function group with a ratio of 50:50.
