摘要: 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.

摘要: An oxide etching method using low-medium density plasma includes a first etching step to pre-etch the oxide layer with low etching selectivity etchant to pre-form a contact opening and a monitoring opening. The low etching selectivity etchant can also etch the photoresist layer and the photoresist reaction residue. Then, a second etching with high etching selectivity on the oxide is performed to completely form the contact opening with a SAC property and the monitoring opening. The openings expose the substrate.

摘要: A method for forming a contact hole in a silicon oxide layer formed over a silicon nitride layer and a substrate performs an etching process with an etchant, C4F8/Ar or C4F8/C2F6/Ar, on an inductively coupled plasma etcher. The inductively coupled plasma etcher contains a chamber, a ring, and a roof. The etchant used in the etching process is controlled by conditions that include a C4F8 flow of about 10 to 20 sccm, a CO flow of less than about 100 sccm, and an Ar flow of about 50 to 500 sccm. In the meantime, the conditions of the inductively coupled plasma etcher include a roof temperature of about 150 to 300 ° C., a ring temperature of about 150 to 400 ° C., and a pressure within the chamber of about 4 to 50 mtorr. By performing a plasma etching process under the foregoing conditions, a properly profiled contact hole is obtained.
