摘要:
A method of fabricating a semiconductor device. A first organic layer, a sacrificial layer, and a second organic layer are sequentially formed on a substrate. Then, a photolithography process is performed for forming a predetermined pattern in the second organic layer. Thereafter, the second organic layer is utilized as an etching mask for etching the sacrificial layer till a surface of the first organic layer is exposed, thus transferring the predetermined pattern to the sacrificial layer. Subsequently, the sacrificial layer is utilized as an etching mask for etching the first organic layer till a surface of the substrate is exposed, thereby transferring the predetermined pattern to the first organic layer. Then, the sacrificial layer and the first organic layer are utilized as an etching mask for etching the substrate, thereby transferring the predetermined pattern to the substrate. Finally, the first organic layer is removed by use of plasma.

A semiconductor wafer comprises a silicon substrate, and a dielectric layer. A gate is formed on the dielectric layer. A first silicon oxide layer is uniformly formed on the semiconductor wafer. A first ion implantation process is performed to form two doped areas on the silicon substrate that are used as two lightly doped drains of a MOS transistor. A second silicon oxide layer is formed on the semiconductor wafer. A sacrificial layer is formed on the second silicon oxide layer. A first etching process is performed to remove the sacrificial layer on top of the gate, causing the gate to protrude from the remaining sacrificial layer for a predetermined height. A second etching process is performed to remove the first and second silicon oxide layers on the protruding portion of the gate. After removing the sacrificial layer completely, a silicon nitride layer is uniformly formed on the semiconductor wafer. A third etching process is performed to vertically remove the silicon nitride layer on top of the gate, thereby forming a spacer. Finally, a second ion implantation process is performed to form two doped areas on the silicon substrate, which are used as source and drain of the MOS transistor.

The present invention provides a method for etching a poly-silicon layer of a semiconductor wafer. The semiconductor wafer comprises a dielectric layer, a poly-silicon layer situated on the dielectric layer and containing dopants to a predetermined depth, and a photo-resist layer having a rectangular cross-section above a predetermined area of the poly-silicon layer. The semiconductor wafer is processed in a plasma chamber. A first dry-etching process is performed to vertically etch away the dopant-containing portion of the poly-silicon layer not covered by the photo-resist layer. Then, a second dry-etching process is performed to vertically etch away the residual portion of the poly-silicon layer not covered by the photo-resist layer down to the surface of the dielectric layer. The etching gases used in the first dry-etching process differ from those used in the second dry-etching process, and the main etching gas of the first dry-etching process is C2F6.

A method of relieving wafer stress is provided. A wafer is provided, wherein at least a dielectric layer has already formed over the wafer and the wafer has a first and a second area. At least no circuits are formed on the dielectric layer within the first area. Thereafter, openings are formed in the dielectric layer within the first area. A material layer is formed over the dielectric layer. Thus, pits are formed on the surface of the material layer at locations above the openings. Through the pits on the material layer, stress within the material layer is relieved and hence the amount of stress conferred to the wafer is reduced.

A method for forming a semiconductor with overetched spacer is disclosed. The method includes firstly providing a semiconductor substrate with a gate oxide layer formed thereon, and forming a polysilicon layer on the gate oxide layer. Next, a photoresist layer is formed on the polysilicon layer to define a gate area, followed by anisotropically etching the polysilicon layer and the gate oxide layer. A first dielectric layer is conformably formed, and a second dielectric layer is then formed thereon. After anisotropically etching the second dielectric layer to form a first sidewall spacer on the sidewall of the first dielectric layer, a third dielectric layer is further formed over the exposed first dielectric layer and the first sidewall spacer. Finally, the third dielectric layer and the first sidewall spacer are anisotropically etched so that a second sidewall spacer is formed on the sidewall of the first sidewall spacer, wherein top surface of the first and the second sidewall spacer is below top surface of the first dielectric layer around the gate area.
