摘要:
Patterning with UV and EUV light is described with organo tin sulfide (and selenide) clusters. The clusters are solids at room temperature and are soluble in organic solvents that are not too polar. Irradiation can either fragment a carbon metal bond or crosslink unsaturated organic moieties to stabilize the irradiated material. The irradiated material then resists dissolving in organic solvents so that the un-irradiated material can be contacted with an organic solvent to develop the latent image formed with the radiation. Radiation patternable layers can be formed through coating a solution or through vapor deposition. Corresponding precursor solutions, structures and methods are described.

The present invention is a composition for forming a silicon-containing resist underlayer film, containing a condensation reaction-type thermosetting silicon-containing material (Sx), being a polysiloxane resin, where the material has a non-condensation reactive organic group that reacts with a radical chemical species, the resin includes more than 0 and 70 mol % or less of one or more of a repeating unit represented by the following general formula (Sx-4) and a repeating unit represented by the general formula (Sx-5), and the organic group remains unreacted after a heat-curing reaction of the polysiloxane resin. This provides: a composition for forming a resist underlayer film containing a thermosetting silicon-containing material in photolithography using a high-energy beam, the material improving sensitivity, LWR, and resolution of an upper layer resist and further contributing to the prevention of pattern collapse; and a patterning process using the composition for forming a resist underlayer film.

The present disclosure relates to a composition formed with a precursor including a C1-4 haloaliphatic or C1-4 aliphatic group or vinyl group (—CH═CH2) and other unsaturated substituents, as well as methods for forming and employing such compositions. In particular embodiments, the haloaliphatic group is a C1-2 haloalkyl group, which in turn provides a resist film having enhanced radiation absorptivity and/or minimal film shrinkage (e.g., upon radiation exposure and/or post-exposure bake). In other embodiments, the aliphatic group is a C1-2 alkyl or vinyl group and other unsaturated substituents, which can be dry deposited. In non-limiting embodiments, the radiation can include extreme ultraviolet (EUV) or deep ultraviolet (DUV) radiation.

Embodiments disclosed herein include methods of depositing a metal oxo photoresist using dry deposition processes. In an embodiment, the method comprises forming a first metal oxo film on the substrate with a first vapor phase process including a first metal precursor vapor and a first oxidant vapor, and forming a second metal oxo film over the first metal oxo film with a second vapor phase process including a second metal precursor vapor and a second oxidant vapor.
摘要:
Organometallic precursors are described for the formation of high resolution lithography patterning coatings based on metal oxide hydroxide chemistry. The precursor compositions generally comprise ligands readily hydrolysable by water vapor or other OH source composition under modest conditions. The organometallic precursors generally comprise a radiation sensitive organo ligand to tin that can result in a coating that can be effective for high resolution patterning at relatively low radiation doses and is particularly useful for EUV patterning. The precursors compositions are readily processable under commercially suitable conditions. Solution phase processing with in situ hydrolysis or vapor based deposition can be used to form the coatings.

The present disclosure provides a semiconductor fabrication method. The method includes modifying an edge portion of a wafer such that the edge portion are prevented from resist coating; coating a resist layer on the front surface of the wafer, wherein the resist layer is free from the edge portion of the wafer; and performing an exposing process to the resist layer.

A vacuum-integrated metal oxide-containing hardmask formation process and related vacuum-integrated hardware that combine steps of film formation by vapor deposition and optical lithography results in direct photopatterning of metal oxide-containing hardmasks at substantially reduced cost relative to current approaches.
摘要:
Methods and apparatus for forming a sacrificial during a novel process sequence of lithography and photoresist patterning are provided. In one embodiment, a method of processing a substrate having a resist material and an anti-reflective coating material thereon includes depositing an organic polymer layer over the surface of the substrate inside a process chamber using a CVD technique. The CVD technique includes flowing a monomer into a processing region of the process chamber, flowing an initiator into the processing region through one or more filament wires heated to a temperature between about 200° C. and about 450° C., and forming the organic polymer layer. In addition, the organic polymer layer is ashable and can be removed from the surface of the substrate when the resist material is removed from the surface of the substrate.
