  • Publication number: 20210320002
    Abstract: A method for preventing the collapse of patterned, high aspect ratio features formed in semiconductor substrates upon removal of an initial fluid of the type used to clean etch residues from the spaces between the features. In the present method, the spaces are at least partially filled with a displacement solution, such as via spin coating, to substantially displace the initial fluid. The displacement solution includes at least one solvent and at least one fill material in the form of a water-soluble polymer such as polyvinylpyrrolidone (PVP) or polyacrylamide (PAAM). The solvent is then volatized to deposit the fill material in substantially solid form within the spaces. The fill material may be removed by known plasma ash process via a high ash rate as compared to use of current fill materials, which prevents or mitigates silicon loss.

  • Patent number: 10748757
    Abstract: A method for preventing the collapse of patterned, high aspect ratio features formed in semiconductor substrates upon removal of wash solutions of the type used to clean etch residues from the spaces between the features. In the present method, the spaces are at least partially filled with a displacement solution, such as via spin coating, to substantially displace the wash solution. The displacement solution includes at least one solvent and at least one fill material which is a polyalkene carbonate (PAC) and/or a saccharide. The solvent is then volatized to deposit the fill material in substantially solid form within the spaces. The fill material may be removed by thermal degradation via heat treatment, wherein the need for removal of the fill material by plasma ashing is obviated in order to prevent or mitigate silicon loss.

  • Patent number: 6967172
    Abstract: A colloidal suspension of nanoparticles composed of a dense material dispersed in a solvent is used in forming a gap-filling dielectric material with low thermal shrinkage. The dielectric material is particularly useful for pre-metal dielectric and shallow trench isolation applications. According to the methods of forming a dielectric material, the colloidal suspension is deposited on a substrate and dried to form a porous intermediate layer. The intermediate layer is modified by infiltration with a liquid phase matrix material, such as a spin-on polymer, followed by curing, by infiltration with a gas phase matrix material, followed by curing, or by curing alone, to provide a gap-filling, thermally stable, etch resistant dielectric material.
