CMP Polishing Liquid and Polishing Method

A CMP polishing liquid being capable of using in a chemical mechanical polishing comprising of: a first chemical mechanical polishing step of polishing a conductive substance layer of a substrate having an interlayer insulation film containing convex and concave regions on a surface thereof, a barrier layer coating along the surface of the interlayer insulation film, and the conductive substance layer coating the barrier layer while filling the concave regions, and thus exposing the barrier layer in the convex regions; and a second chemical mechanical polishing step of exposing the interlayer insulation film in the convex regions by polishing the barrier layer exposed in the first chemical mechanical polishing step; characterized in that a difference (B)−(A) is 650 {acute over (Å)} or less,
    • wherein the (A) is a polishing amount of the interlayer insulation film in a field area when the interlayer insulation film in the field area having a width of 1,000 μm or more of the interlayer insulation film region formed on the substrate is polished to a depth of 400 {acute over (Å)} or more; and
    • the (B) is a polishing amount of the interlayer insulation film in a stripe-shaped patterned area having a total width of 1,000 μm or more wherein a wiring metal region having a width of 90 μm and the interlayer insulation film region having a width of 10 μm are aligned alternately on the substrate when the interlayer insulation film in the field area having the width of 1,000 μm or more of the interlayer insulation film region formed on the substrate is polished to a depth of 400 {acute over (Å)} or more.

Preparation method of elastic polyester fiber and flax fiber blended yarns by adopting bio-enzyme method

The invention discloses a preparation method of elastic polyester fiber and flax fiber blended yarns by adopting a bio-enzyme method. The weight content of flax fibers is 45 percent to 75 percent and the balance is elastic polyester fibers; the preparation method comprises: pre-treating, blowing, cotton carding, drawing, roving, degumming, bleaching, acid washing, washing and spinning. By adopting the preparation method provided by the invention, the elastic polyester fiber and flax fiber blended yarns with moisture absorption, lightness and thinness, glossiness, air permeability, antibacterial property and mite inhibition property can be prepared. The elastic polyester fiber and flax fiber blended yarns provided by the invention have high spinnability and good elasticity; cloth woven by the elastic polyester fiber and flax fiber blended yarns is light and soft, comfortable and breathable, has sweat-absorbing and antibacterial properties and has elasticity; the cloth has novel and fashionable appearance. The elastic polyester fibers and the flax fibers are blended and the disadvantage of low elasticity of the flax fibers can be made up; a prepared fabric has a comfortable hand feeling and has good elasticity; the style of the blended yarns can be improved and the hand feeling of the blended yarns can be improved.
