چکیده

A new low-cost, high throughput method was developed for fabricating large area quantized magnetic disks ~QMDs! using nanoimprint lithography ~NIL!, electroplating, and chemical mechanical polishing. Perpendicular QMDs with a density of 18 Gbit/in. and good uniformity over an area of 4 cm34 cm ~total 45 Gbit! have been achieved, as well as longitudinal QMDs of 30 Gbit/in. The NIL molds for the perpendicular QMDs were fabricated using double NIL with a grating mold. The magnetic properties of both types of QMDs were studied by magnetic force microscopy. © 1998 American Vacuum Society. @S0734-211X~98!15406-9#

Perpendicular quantized magnetic disks with 45 Gbits on a 4 3 4 cm 2 area

Quantized magnetic disks consisting of an array of single domain Ni pillars with a density of 18 Gbits/in. were fabricated using nanoimprint lithography ~NIL! and electroplating. The total disk area, limited by the NIL mold, is 4 cm34 cm, leading to a total 45 Gbits. Magnetic force microscope ~MFM! images show that all pillars 70 nm in diameter and 400 nm in height are single domain. The magnet...

Injection Compression Molding of Replica Molds for Nanoimprint Lithography

As a breakthrough in the cost and durability of molds for nanoimprint lithography (NIL), replica molds are fabricated by injection compression molding (ICM). ICM is commonly used for optical disks such as DVDs or Blu-ray disks and is also a practical fabrication method for nanostructures. In this paper, I successfully demonstrated the fabrication of cycloolefin polymer replica molds with struct...

Large area high density sub-20 nm SiO(2) nanostructures fabricated by block copolymer template for nanoimprint lithography.

We developed simple fabrication methods to effectively transfer the block copolymer nanopatterns to a substrate material. High aspect ratio, sub-20 nm nanopillar and nanohole structures are successfully fabricated in a SiO(2) layer in large area format, and the versatile utilities of these nanostructures as nanoimprint molds are studied. Nanoimprint lithography using these molds makes it possib...

Nano-compact disks with 400 Gbit/in2 storage density fabricated using nanoimprint lithography and read with proximal probe

Nano-compact disks ~Nano-CDs! with 400 Gbit/in topographical bit density ~nearly three orders of magnitude higher than commercial CDs! have been fabricated using nanoimprint lithography. The reading and wearing of such Nano-CDs have been studied using scanning proximal probe methods. Using a tapping mode, a Nano-CD was read 1000 times without any detectable degradation of the disk or the silico...

Fabrication of planar quantum magnetic disk structure using electron beam lithography, reactive ion etching, and chemical mechanical polishing

A planar quantum magnetic disk ~QMD! with a magnetic storage density of 65 Gbit/in., over two orders of magnitude greater than the state-of-the-art magnetic storage density, has been fabricated. The planar QMD structure consists of single-domain nickel ~magnetic! nanopillars uniformly embedded in a SiO2 ~nonmagnetic! disk. Electron beam lithography was used to define the QMD bit’s size and loca...
