    摘要: A method of fabricating a semiconductor integrated circuit (IC) is disclosed. The method includes providing a substrate. A sacrifice layer (SL) is formed and patterned on the substrate. The patterned SL has a plurality of openings. The method also includes forming a metal layer in the openings and then removing the patterned SL to laterally expose at least a portion of the metal layer to form a metal feature, which has a substantial same profile as the opening. A dielectric layer is deposited on sides of the metal feature.

    摘要: A method of forming a fine pattern comprises depositing a modifying layer on a substrate. A photoresist layer is deposited on the modifying layer, the photoresist layer having a first pattern. The modifying layer is etched according to the first pattern of the photoresist layer. A treatment is performed to the etched modifying layer to form a second pattern, the second pattern having a smaller line width roughness (LWR) and/or line edge roughness (LER) than the first pattern. The second pattern is then etched into the substrate.

    摘要: Methods of manufacturing semiconductor devices are disclosed. In one embodiment, a material layer is formed over a workpiece. The workpiece includes a first portion, a second portion, and a hard mask disposed between the first portion and the second portion. The material layer is patterned, and first spacers are formed on sidewalls of the patterned material layer. The patterned material layer is removed, and the second portion of the workpiece is patterned using the first spacers as an etch mask. The first spacers are removed, and second spacers are formed on sidewalls of the patterned second portion of the workpiece. The patterned second portion of the workpiece is removed, and the hard mask of the workpiece is patterned using the second spacers as an etch mask. The first portion of the workpiece is patterned using the hard mask as an etch mask.

    摘要: The present disclosure relates to a structure and method to create a self-repairing dielectric material for semiconductor device applications. A porous dielectric material is deposited on a substrate, and exposed with treating agent particles such that the treating agent particles diffuse into the dielectric material. A dense non-porous cap is formed above the dielectric material which encapsulates the treating agent particles within the dielectric material. The dielectric material is then subjected to a process which creates damage to the dielectric material. A chemical reaction is initiated between the treating agent particles and the damage, repairing the damage. A gradient concentration resulting from the consumption of treating agent particles by the chemical reaction promotes continuous diffusion the treating agent particles towards the damaged region of the dielectric material, continuously repairing the damage.
