    摘要: A transistor having a metal nitride layer pattern, etchant and methods of forming the same is provided. A gate insulating layer and/or a metal nitride layer may be formed on a semiconductor substrate. A mask layer may be formed on the metal nitride layer. Using the mask layer as an etching mask, an etching process may be performed on the metal nitride layer, forming the metal nitride layer pattern. An etchant, which may have an oxidizing agent, a chelate agent and/or a pH adjusting mixture, may perform the etching. The methods may reduce etching damage to a gate insulating layer under the metal nitride layer pattern during the formation of a transistor.

    摘要: Spaced apart bonding surfaces are formed on a first substrate. A second substrate is bonded to the bonding surfaces of the first substrate and cleaved to leave respective semiconductor regions from the second substrate on respective ones of the spaced apart bonding surfaces of the first substrate. The bonding surfaces may include surfaces of at least one insulating region on the first substrate, and at least one active device may be formed in and/or on at least one of the semiconductor regions. A device isolation region may be formed adjacent the at least one of the semiconductor regions.

    摘要: A sacrificial layer and wet etch are used to form a sidewall spacer so as to prevent damage to the structure on which the spacer is formed and to the underlying substrate as well. Once the structure is formed on the substrate a spacer formation layer is formed to cover the structure, and a sacrificial layer is formed on the spacer formation layer. The sacrificial layer is wet etched to form a sacrificial layer pattern on that portion of the spacer formation layer extending along a sidewall of the structure. The spacer is formed on the sidewall of the structure by wet etching the spacer formation layer using the sacrificial layer pattern as a mask.

    摘要: In a wiring structure of a semiconductor device and a method of manufacturing the same, a wiring structure includes a contact pad, a contact plug, a spacer and an insulation interlayer pattern. The contact pad is electrically connected to a contact region of a substrate. The contact plug is provided on the contact pad and is electrically connected to the contact pad. The spacer faces an upper side surface of the contact pad and sidewalls of the contact plug. The insulation interlayer pattern has an opening, the contact plug and the spacer being provided in the opening. The spacer of the wiring structure may prevent the contact pad from being damaged by a cleaning solution while forming a contact plug to be connected to a capacitor.

    摘要: The exemplary embodiments of the present invention providing new slurry compositions suitable for use in processes involving the chemical mechanical polishing (CMP) of a polysilicon layer. The slurry compositions include one or more non-ionic polymeric surfactants that will selectively form a passivation layer on an exposed polysilicon surface in order to suppress the polysilicon removal rate relative to silicon oxide and silicon nitride and improve the planarity of the polished substrate. Exemplary surfactants include alkyl and aryl alcohols of ethylene oxide (EO) and propylene oxide (PO) block copolymers and may be present in the slurry compositions in an amount of up to about 5 wt %, although much smaller concentrations may be effective. Other slurry additives may include viscosity modifiers, pH modifiers, dispersion agents, chelating agents, and amine or imine surfactants suitable for modifying the relative removal rates of silicon nitride and silicon oxide.
