    摘要: Methods and heat treatment apparatus for heating a substrate and any layer carried on the substrate during a bake process. A heat exchange gap between the substrate and a heated support is at least partially filled by a gas having a high thermal conductivity. The high thermal conductivity gas is introduced into the heat exchange gap by displacing a lower thermal conductivity originally present in the heat exchange gap when the substrate is loaded. Heat transfer across the heat exchange gap is mediated by the high thermal conductivity gas.

    摘要: Disclosed is a method and apparatus for mitigation of photoresist line pattern collapse in a photolithography process by applying a gap-fill material treatment after the post-development line pattern rinse step. The gap-fill material dries into a solid layer filling the inter-line spaces of the line pattern, thereby preventing line pattern collapse due to capillary forces during the post-rinse line pattern drying step. Once dried, the gap-fill material is depolymerized, volatilized, and removed from the line pattern by heating, illumination with ultraviolet light, by application of a catalyst chemistry, or by plasma etching.

    摘要: A method of patterning a substrate using a dual-tone development process is described. The patterning method comprises forming a layer of radiation-sensitive material on a substrate, wherein the layer of radiation-sensitive material comprises a dual tone resist. Thereafter, the patterning method comprises performing one or more exposures of the layer of radiation-sensitive material to one or more patterns of radiation, wherein at least one of the one or more exposures comprises using a mask having a dual-tone mask pattern region configured for printing dual tone features and a half-tone mask pattern region configured for printing half-tone features. Furthermore, the half-tone mask pattern region is optimized for use with the dual tone resist.

    摘要: A method for etching a pattern on a surface is disclosed. A mask layer is disposed over a surface and a resist is disposed over the mask layer. The resist is exposed to light through the mask exposing primary pattern and sidelobe regions. The resist is developed and the mask layer is etched according to the resist pattern. A first material is deposited over the mask layer, wherein a gap is formed beneath the material and over the primary pattern region. The material is etched back so that the gap is exposed, and the primary pattern region is etched using the first material as a mask.
