摘要: A method for forming a platen useful for forming nanoscale wires for device applications comprises: (a) providing a substrate having a major surface; (b) forming a plurality of alternating layers of two dissimilar materials on the substrate to form a stack having a major surface parallel to that of the substrate; (c) cleaving the stack normal to its major surface to expose the plurality of alternating layers; and (d) etching the exposed plurality of alternating layers to a chosen depth using an etchant that etches one material at a different rate than the other material to thereby provide the surface with extensive strips of indentations and form the platen useful for molding masters for nano-imprinting technology. The pattern of the platen is then imprinted into a substrate comprising a softer material to form a negative of the pattern, which is then used in further processing to form nanowires. The nanoscale platen thus comprises a plurality of alternating layers of the two dissimilar materials, with the layers of one material etched relative the layers of the other material to form indentations of the one material. The platen is then oriented such that the indentations are parallel to a surface to be imprinted.

摘要: Controlling ion/radical ratio and monoatomic/polyatomic radical ratio in a process plasma provides improved processing performance during inductively-coupled plasma and/or helicon wave plasma processing of substrate materials. In a plasma processing method employing inductively coupled plasma, high frequency current to a high frequency antenna is intermittently supplied in a controlled manner to control the state of gas dissociation to promote formation of polyatomic radicals. In a plasma processing method employing helicon wave plasma, current supplied to a magnetic field generator is intermittently supplied in a controlled manner to promote formation of ions. In a preferred method, both the high frequency current and magnetic field generating current are varied in a controlled manner to provide a variable plasma composition, i.e., radical rich plasma or ion-rich plasma, as desired, for improved plasma processing, especially improved selective anisotropic dry etching at high etch rate.

摘要: Aspects of the invention are directed to a method for forming a semiconductor device. A dielectric layer is formed on a semiconductor substrate. Subsequently, a metallic contact is formed in the dielectric layer such that it lands on the semiconductor substrate. A masking layer comprising a block copolymer is then formed on the dielectric layer. This block copolymer is caused to separate into two phases. One of the two phases is selectively removed to leave a patterned masking layer. The patterned masking layer is used to etch the dielectric layer. The patterned air gaps reduce the interconnect capacitance of the semiconductor device while leaving the dielectric layer with enough mechanical strength to serve as a middle-of-line dielectric.
