Patent number: 7573081Abstract: A new method is provided for creating an inductor on the surface of a silicon substrate. The invention provides overlying layers of oxide fins beneath a metal inductor. The oxide fins provide the stability support for the overlying metal inductor while also allowing horizontal air columns to simultaneously exist underneath the inductor. Overlying layers of air cavities that are spatially inserted between the created overlying layers of oxide fins can be created under the invention by repetitive application of the mask used. The presence of the air wells on the surface of the substrate significantly reduces parasitic capacitances and series resistance of the inductor associated with the substrate.Type: GrantFiled: September 11, 2006Date of Patent: August 11, 2009Assignees: Chartered Semiconductor Manufacturing Ltd., National University of SingaporeInventors: Lap Chan, Kok Wai Johnny Chew, Cher Liang Cha, Chee Tee Chua

Patent number: 6764914Abstract: A process for forming a high dielectric constant, (High K), layer, for a metal-oxide-metal, capacitor structure, featuring localized oxidation of an underlying metal layer, performed at a temperature higher than the temperature experienced by surrounding structures, has been developed. A first iteration of this process features the use of a laser ablation procedure, performed to a local region of an underlying metal layer, in an oxidizing ambient. The laser ablation procedure creates the desired, high temperature, only at the laser spot, allowing a high K layer to be created at this temperature, while the surrounding structures on a semiconductor substrate, not directly exposed to the laser ablation procedure remain at lower temperatures.Type: GrantFiled: November 7, 2002Date of Patent: July 20, 2004Assignee: Chartered Semiconductor Manufacturing Ltd.Inventors: Alex See, Cher Liang Randall Cha, Shyue Fong Quek, Ting Cheong Ang, Wye Boon Loh, Sang Yee Loong, Jun Song, Chua Chee Tee

Patent number: 6348385Abstract: The method for a transistor using a replacement gate process that has a doped low-K dielectric spacer that lowers the junction capacitance. A dummy gate is formed over a substrate. Ions are implanted into the substrate using the dummy gate as an implant mask to form source and drain regions. A masking layer is formed on the substrate over the source and drain regions. We remove the dummy gate. Doped low k spacers are formed on the sidewalls of the masking layer. The doped spacers are heated to diffuse dopant into the substrate to form lightly doped drain (LDD regions). We form a high k gate dielectric layer over the masking layer. A gate layer is formed over the high K dielectric layer. The gate layer is chemical-mechanical polished (CMP) to form a gate over the high k dielectric layer and to remove the gate layer over the masking layer.Type: GrantFiled: November 30, 2000Date of Patent: February 19, 2002Assignee: Chartered Semiconductor Manufacturing Ltd.Inventors: Randall Cher Liang Cha, Tae Jong Lee, Alex See, Lap Chan, Chee Tee Chua

Patent number: 6121130Abstract: A process for curing low-k spin-on dielectric layers based on alkyl silsesquioxane polymers by laser scanning is described wherein curing is achieved by both photothermal and photochemical mechanisms. The layers are deposited by spin deposition, dried and cured by raster scanning with a pulsed laser at energies between 0.1 and 1 Joules/cm.sup.2. Because the laser causes heating of the layer, a nitrogen jet is applied in the wake of the scanning laser beam to rapidly cool the layer and to inhibit oxidation and moisture absorption. The laser induced heating also assists in the discharge of moisture and by-products of the polymerization process. The laser operates at wavelengths between 200 and 400 nm. Insulative layers such as silicon oxide are sufficiently transparent at these so that oxide segments overlying the polymer layer do not inhibit the curing process. Implementation of the laser scanning feature is readily incorporated into an existing spin-on deposition and curing tool.Type: GrantFiled: November 16, 1998Date of Patent: September 19, 2000Assignees: Chartered Semiconductor Manufacturing Ltd., National Univ. of Singapore, Nanyang Technology Univ.Inventors: Chee Tee Chua, Yuan-Ping Lee, Mei Sheng Zhou, Lap Chan
