Abstract: The invention provides a method of making silicon-on-glass substrates used in the manufacture of flat panel displays. A layer of amorphous silicon film is deposited on a glass substrate. The amorphous silicon is annealed by excimer laser annealing, transforming the amorphous silicon into polycrystalline silicon. The excimer laser annealing is carried out in a predominantly air ambient environment at atmospheric pressure and room temperature. The process requires no environmental chamber to house the substrate during excimer laser annealing. The process displaces the ambient air immediately surrounding the target region on the surface of the silicon film, where the laser beam strikes the silicon film, with inert gas. As a result, the ambient environment at the point of annealing on the substrate is depleted of oxygen and the oxygen content of the resultant polycrystalline silicon layer is kept below a predetermined level.

Abstract: The present invention is a method and apparatus for filling voids in a substrate with a desired material to form conductive components and/or other features on the substrate. In one embodiment in accordance with the principles of the present invention, a substrate with voids is covered with a first layer of material and then a second layer of material is formed on top of the first layer. The first layer is deformable at a deformation temperature, while the second layer has a higher yield strength than the first layer and is substantially non-deformable at the deformation temperature. The second layer, for example, may be a rigid and/or substantially incompressible layer that distributes a driving force to the first layer. The second layer is then pressed against the first layer at a temperature equal to or greater than the deformation temperature to drive portions of the first layer into the voids in the substrate.

Abstract: A method for improving the planarization of a dielectric layer in the fabrication of metallic interconnects wherein a rapid thermal processing operation is used in order to consolidate exposed surfaces of a dielectric layer after local planarization of the dielectric layer. This method avoids damage to the dielectric layer caused during a pre-metal etching operation, and consequently, prevents residual tungsten from becoming lodged in fissures during subsequent tungsten deposition to produce stringers which may cause short circuiting on coming in contact with metal wiring.

Abstract: An Al alloy interconnection layer is deposited on a silicon oxide layer, and a first carbon layer is formed on the Al alloy interconnection layer. Then, the first carbon layer and the Al alloy interconnection layer are patterned, thereby forming a first interconnection layer consisting of the Al alloy interconnection layer and the first carbon layer. Sequentially, a second carbon layer is formed on the first interconnection layer and the silicon oxide layer. The second carbon layer is entirely etched by the RIE method, thereby leaving the second carbon layer only on side surfaces of the first interconnection layer. A high temperature layer made of SiO.sub.2 is deposited on the second carbon layer, the first interconnection layer and the silicon oxide layer. Thereafter, the high temperature layer is etched back until the first carbon layer is exposed, thus being flattened. An interlayer insulating layer is deposited on the high temperature layer and the first interconnection layer.
