摘要:
A method of self-assembling density multiplied block copolymers (BCP) structures includes applying a block copolymer (BCP) to a feature-imprinted resist layer. The BCP is thermally annealed to laterally segregate the BCP into self-assembled columns of a first polymer block surrounded by a second polymer block.

A data storage medium is provided according to the present invention for magnetic recording. The data storage medium includes a substrate having a locking pattern etched therein defining patterned regions. The patterned regions are chemically modified by depositing a self-assembled monolayer therein. A first layer of nanoparticles is provided in the patterned regions on top of the self-assembled monolayer and is chemically bonded to the substrate via the self-assembled monolayer. The first layer of nanoparticles is chemically modified using functional surfactant molecules applied thereto, such that a second layer of nanoparticles may be formed on top of the first layer and chemically bonded thereto via the functional surfactant molecules. Additional layers of nanoparticles may be applied by chemically modifying the top layer of nanoparticles utilizing the functional surfactant molecules and applying a further layer of nanoparticles thereto.

A lithography method for plating sub-100 nm narrow trenches, including providing a thin undercoat dissolution layer intermediate a seed layer and a resist layer, wherein the undercoat dissolution layer is relatively completely cleared off the seed layer by the developer solution such that the sides of the narrow trench will be generally vertical, particularly at the base of the narrow trench, thus facilitating plating the narrow trench with a high magnetic moment material.

A method for forming a magnetic write pole with a trapezoidal cross-section is described. The method consists of first forming a magnetic seedlayer on a base followed by depositing a removable material layer on the seedlayer, and then a resist layer on the removable material layer. A trench is then formed in the resist, and the resist is heated to cause the cross -sectional profile of the trench to assume a trapezoidal shape. The resist is then capped with another resist layer and further heated to cause the width of the trapezoidal trench to become narrower. The cap layer and removable material layer at the bottom of the trench are then removed and the trench filled with magnetic material by electroplating. The resist and seedlayer external to the trench are finally removed to form a write pole with a trapezoidal cross-section.

The formation of a device using block copolymer lithography is provided. The formation of the device includes forming a block copolymer structure. The block copolymer structure includes a first polymer and a second polymer. The block copolymer structure also includes a first component deposited between adjacent blocks of the first polymer and a second component deposited between adjacent blocks of the second polymer. A template is developed by removing either the first and second polymers or the first and second components from the block copolymer structure. The formation of the device also includes lithographically patterning the device utilizing the block copolymer structure template. The device may be a data storage medium.

This disclosure describes a method for nano-patterning by incorporating one or more block copolymers and one or more nano-imprinting steps in the fabrication process. The block copolymers may be comprised of organic or organic components, and may be lamellar, spherical or cylindrical. As a result, a patterned medium may be formed having one-dimensional or two-dimensional patterns with a feature pitch of 5-100 nm and/or a bit density of at least 1 Tdpsi.
