Abstract
The invention includes methods of forming capacitor structures and removing organic material. An organic material, such as a photoresist, is disposed on a substrate. The organic material is contacted with a chemical mechanical polishing pad and a polishing fluid to remove the organic material from the substrate. The polishing fluid can be essentially free of particles, and can be water.
Claims
exact text as granted — not AI-modified1 - 53 . (canceled)
54 . Removing carbon-comprising material from above a substrate with a pad and a fluid, the fluid comprising a particulate concentration of less than or equal to about 0 . 1 weight percent at an initiation of the removing.
55 . The removing of claim 54 wherein, the pad is a chemical-mechanical-polishing pad.
56 . The removing of claim 54 wherein, the substrate is semiconductive.
57 . The removing of claim 54 wherein, the fluid is substantially unreactive with the substrate.
58 . The removing of claim 54 wherein, the carbon-comprising material also comprises both oxygen and hydrogen.
59 . The removing of claim 54 wherein, the carbon-comprising material comprises a resist-material.
60 . A carbon-comprising material removal system, comprising:
a substrate support configured to support a substrate having a carbon-comprising material thereon; a pad configured to physically contact the carbon-comprising material; and a fluid source, the fluid source configured to provide a fluid to a location between the pad and the material, the fluid comprising a particulate concentration of less than or equal to about 0.1 weight percent.
61 . The system of claim 60 wherein the substrate comprises both semiconductive material and conductive material, the conductive material forming a surface of the substrate and having the carbon-comprising material thereon.
62 . The system of claim 60 wherein the pad is a chemical-mechanical-polishing pad.
63 . The system of claim 62 wherein the pad includes a surface facing the carbon-comprising material, the surface of the pad comprising a polyurethane-material.
64 . The system of claim 60 wherein the pad is configured to rotate about an axis.
65 . The system of claim 60 wherein the pad is configured to have linear motion along an axis.
66 . The system of claim 60 wherein the fluid comprises an additive, the additive being both reactive with the carbon-comprising material and unreactive with the substrate.
67 . The system of claim 66 wherein the additive comprises TMAH.
68 . An integrated circuitry manufacturing process, comprising:
applying a mask above a semiconductive substrate; creating a recess within the substrate using the mask; and removing at least a portion of the mask with a pad and fluid, the fluid substantially lacking in particulates.
69 . The process of claim 68 wherein substrate comprises a conductive material and a semiconductive material, the conductive material being a surface of the substrate and contacting the mask.
70 . The process of claim 68 wherein the recess is created in at least the conductive material.
71 . The process of claim 68 wherein during the removing of the portion of the mask the fluid does not react with the conductive material.
72 . The process of claim 68 wherein the mask comprises one of photoresist material or non-photosensitive resist material.
73 . The process of claim 68 wherein the mask comprises a polyimide material.Join the waitlist — get patent alerts
