Abstract:
Methods for polishing multiple dielectric layers to form replacement metal gate structures include a first chemical mechanical polish step to remove overburden and planarize a top layer to leave a planarized thickness over a gate structure. A second chemical mechanical polish step includes removal of the thickness to expose an underlying covered surface of a dielectric of the gate structure with a slurry configured to polish the top layer and the underlying covered surface substantially equally to accomplish a planar topography. A third chemical mechanical polish step is employed to remove the dielectric of the gate structure and expose a gate conductor.
Abstract:
A polishing method includes polishing, in a first polish, a wafer to remove overburden and planarize a top layer leaving a portion remaining on an underlying layer. A second polishing step includes two phases. In a first phase, the top layer is removed and the underlying layer is exposed, with a top layer to underlying layer selectivity of between about 1:1 to about 2:1 to provide a planar topography. In a second phase, residual portions of the top layer are removed from a top of the underlying layer to ensure complete exposure of an underlying layer surface.
Abstract:
A planarization method includes planarizing a semiconductor wafer in a first chemical mechanical polish step to remove overburden and planarize a top layer leaving a thickness of top layer material over underlying layers. The top layer material is planarized in a second chemical mechanical polish step to further remove the top layer and expose underlying layers of a second material and a third material such that a selectivity of the top layer material to the second material to the third material is between about 1:1:1 to about 2:1:1 to provide a planar topography.

A method of forming the laminate includes: forming a first coating for a first silica-based film on a substrate; forming a second coating for a second silica-based film on the first coating, the second coating including an organic group containing a carbon-carbon double bond or a carbon-carbon triple bond; forming a third coating for an organic film on the second coating; and curing a multilayer film including the first to third coatings.
Abstract:
A toner replenishing device includes a toner conveying portion, a conveying member, a toner loosening member and a swinging member. The toner conveying portion has a vertical conveying portion for vertically conveying toner, and a horizontal conveying portion for horizontally conveying the toner. The conveying member is disposed in the horizontal conveying portion, and has a shaft member and a projecting portion formed around the shaft member. The toner loosening member is disposed in the vertical conveying portion to be swingable up and down. The swinging member is contactable with the conveying member and the toner loosening member. The swinging member swings up and down by a change in a contact portion with respect to the conveying member between the shaft member and the projecting portion, as the conveying member rotates. The toner loosening member swings up and down as the swinging member swings.
