摘要:
There is provided a method of performing a surface treatment, such as coating, denaturation, modification and etching, on a surface of a substrate. The method comprises the steps of bringing a surface treatment gas into contact with a surface of a substrate, and irradiating the surface of the substrate with a fast particle beam to enhance an activity of the surface and/or the surface treatment gas, thereby facilitating a reaction between the surface and the gas. The fast particle beam may be selected from a group consisting of an electron beam, a charged particle beam, an atomic beam and molecular beam. For example, during a coating operation, chemical deposition of predetermined component elements of the gas onto the surface is effected and a predetermined portion of the surface of the substrate is irradiated with a particle beam to form a coating layer on the predetermined portion.

The present invention relates to a method and apparatus for forming interconnects on a substrate such as a semiconductor wafer by filling a conductive material such as copper (Cu) in fine recesses formed in a surface of the substrate. A method for forming interconnects comprises providing a substrate and a target composed of a conductive material in confrontation with each other in a chamber, introducing a sputtering gas into the chamber while a high voltage is applied between the substrate and the target to cause the sputtering gas to collide with the target, and depositing particles of the conductive material emitted from the target on the surface of the substrate to form a thin film, while sputter-etching the thin film by reflection sputtering gas molecules reflected from the target and having high energy.

Embedded interconnections of copper are formed by forming an insulating layer, forming embedded interconnections of copper in the insulating layer, making an exposed upper surface of the insulating layer and an exposed surface of the embedded interconnections of copper coplanar according to chemical mechanical polishing, and forming a protective silver film on the exposed surface of the embedded interconnections of copper. These steps are repeated on the existing insulating layer thereby to produce multiple layers of embedded interconnections of copper. The exposed surface of the embedded interconnections of copper is plated with silver according to immersion plating.

A liquid material such as molten silicon is stored in a crucible. A liquid material, which is identical to and held in the same conditions as the liquid material in the crucible, is continuously supplied from an auxiliary crucible to the crucible to keep constant the surface level of the liquid material in the crucible. The liquid material is continuously pulled up from the crucible at a predetermined speed while the liquid material is being solidified into a solid material such as a ribbon-like thin web of single-crystal silicon.
