Poly etching
WebPatterning of cross-linked hydrophilic polymer features using reactive ion etching (RIE) capable of covalently immobilizing proteins has been achieved. Projection photolithography was used to pattern photoresist to create micromolds. Vapor phase molecular self-assembly of polymerizable monolayer in molds allowed covalent binding of hydrogel on surface … WebJul 26, 1999 · wet etching the second polysilicon material to form a buried strap in each trench by employing one of ammonium hydroxide and potassium hydroxide at temperatures of between about 25° C. to about 85° C. to etch back the second polysilicon material selective to the substrate and the nitride liner in a batch process. 23.

WebAn anisotropic polysilicon etching process in Cl 2 /HBr/He is disclosed. The use of HBr allows etching to occur under high poly:oxide selectivity conditions (e.g., above 40:1) that would otherwise produce lateral etching of the poly under the photoresist mask (isotropy). The selectivity of poly:resist is also increased (e.g., above 4:1). WebDX. Etch 37 Dental Etching Gel Best Seller! The DX. Etch 37 Dental Etching Gel is a polymer thickened gel for use on enamel and dentin. This gel will effectively treat enamel and dentin, producing the necessary microretentive surface for successful bonding. The polymer thickener creates thixotropic properties, enhancing handling characteristics. The etchant …
