Abstract:
A method of manufacturing a bottom electrode of a capacitor. A first dielectric layer is formed on a substrate. A cap layer is formed on the first dielectric layer. A second dielectric layer is formed on the cap layer. A node contact hole is formed to penetrate through the second dielectric layer, the cap layer and the first dielectric layer. A liner layer is formed on a sidewall of the node contact hole. A restraining layer is formed on the second dielectric layer. A patterned conductive layer is formed on a portion of the restraining layer and fills the node contact hole. A selective hemispherical grained layer is formed on the patterned conductive layer.
Abstract:
A method for forming a multi-layered liner on the sidewalls of a node contact opening includes the steps of providing a substrate having a dielectric layer thereon. The dielectric layer further includes a node contact opening that exposes a portion of the substrate. A first liner layer is then formed on the sidewalls of the node contact opening. Next, a second liner layer is formed over the first liner layer such that the first liner layer and the second liner layer together form a dual-layered liner. The first liner layer in contact with the dielectric layer has good insulation capacity while the second liner layer has good etch-resisting property.
Abstract:
A method for forming an electrode of semiconductor device capacitor is disclosed. The method comprises forming a dielectric layer on a semiconductor substrate and then using photolithographic method to etch a trench through the dielectric layer to expose specific part of the semiconductor substrate. A polysilicon layer is then formed over the dielectric layer and filled the trench. The polysilicon layer is patterned by a photoresist layer and etched back to the dielectric layer, then a polysilicon rod is formed. A spacer method is used to form an amorphized silicon spacer is sidewall of the polysilicon rod. The polysilicon rod is then implanted to form an amorphized polysilicon layer on top surface of the polysilicon rod. Final hemispherical grain silicon is formed on the spacer and the amorphized polysilicon layer to increase the surface area of the polysilicon rod. Thereby, an electrode of a semiconductor device capacitor is formed, and the capacitance of capacitor is enhanced.
