  • Patent number: 9412613
    Abstract: Embodiments described herein provide for a method of forming an etch selective hardmask. An amorphous carbon hardmask is implanted with various dopants to increase the hardness and density of the hardmask. The ion implantation of the amorphous carbon hardmask also maintains or reduces the internal stress of the hardmask. The etch selective hardmask generally provides for improved patterning in advanced NAND and DRAM devices.

  • Patent number: 8158425
    Abstract: A cell culture scaffold containing a gel having a network structure comprised of a synthetic polymer such that cultured cells spread in a shorter time and the number of adsorbed cultured cells per unit area is larger than in the case of using a gel having a network structure comprised of polyacrylic acid, while taking advantage of synthetic polymers with low manufacturing cost, easy quality control and no risk of virus infection in cultured cell. Used as the cell culture scaffold is a gel containing a synthetic polymer obtained by polymerization or copolymerization of a monomer having a sulfonic group such as p-styrenesulfonic acid sodium salt (NaSS) and 2-acrylamide-2-methylpropane sulfonic acid sodium salt (NaAMPS).

  • Publication number: 20120085733
    Abstract: Embodiments of the present invention pertain to methods of forming features on a substrate using a self-aligned triple patterning (SATP) process. A stack of layers is patterned near the optical resolution of a photolithography system using a high-resolution photomask. The heterogeneous stacks are selectively etched to undercut a hard mask layer beneath overlying cores. A dielectric layer, which is flowable during formation, is deposited and fills the undercut regions as well as the regions between the heterogeneous stacks. The dielectric layer is anisotropically etched and a conformal spacer is deposited on and between the cores. The spacer is anisotropically etched to leave two spacers between each core. The cores are stripped and the spacers are used together with the remaining hard mask features to pattern the substrate at triple the density of the original pattern.
