摘要： A micro-lens array and a method for making are described. The micro-lens array includes a base element and a plurality of lenses formed of an epoxy and including nanoparticles. The micro-lens array is formed from a master micro-lens array, which is placed within a replica micro-lens making assembly. The master micro-lens array is coated with an anti-stiction material prior to having an elastomeric material positioned over it and cured. Removal of the elastomeric material provides a plurality of cavities, which are filled with an epoxy including nanoparticles. Curing of the epoxy finishes the fabrication of the micro-lens array. The lenses of the micro-lens array are formed from a colloidal suspension of nanoparticles and resin.

摘要： A MEMS device and a method for making a MEMS device are described. The MEMS device includes a support member, an optical device, and a flexible member. In one aspect, the flexible member is formed separately from the support member and the optical device. In one aspect, the flexible member is dimensioned to enable flex in one direction while maintaining stiffness in two orthogonal directions. In one fabrication embodiment, the MEMS device is formed by etching an opening into the structural layer to create a structural support member and an optical device. The structural support member and optical device are mounted on a support substrate with a sacrificial layer. A flexible member is conformally deposited over the structural support member and the optical device and then etched. The sacrificial layer is partially etched away to leave the structural support member anchored to the support substrate.

摘要： The invention is directed to a method and apparatus of projection lithography in which the contrast introduced into a radiation sensitive material caused by the proximity effect is effectively removed in a single exposure. Patterned radiation is transmitted through a lens system with at least one lens and a back focal plane filter. The back focal plane filter has at least two apertures, an image aperture and a proximity effect correction aperture. Patterned radiation is transmitted through the image aperture and introduces the desired image into the energy sensitive resist material. A portion of the inverse pattern radiation is transmitted through the proximity effect correction aperture and onto the energy sensitive resist material to effectively remove the contrast therein caused by the proximity effect.

摘要： A process for controlling the stress of multilayer films formed on a substrate is disclosed. A plurality of periods, each period having at least two layers of material wherein one of the layers of material is under compressive stress and the other layer of material is under tensile stress, are formed in a substrate. The stress in the multilayer film is controlled by selecting a thickness for the layer under compressive stress and a thickness for the layer under tensile stress that will provide a multilayer film of the desired stress. The thickness of each layer is about 0.5 nm to about 10 nm. Multilayer films with a stress of about -50 MPa to about 50 MPa are obtained using the present process. The present invention is also directed to masks with such multilayer films.

摘要： An electron beam lithographic apparatus has an electron gun providing a beam of accelerated electrons, a mask stage adapted to hold a mask in a path of the beam of accelerated electrons, and a workpiece stage adapted to hold a workpiece in a path of electrons that have passed through the mask. The electron gun has a cathode having an electron emission surface, an anode adapted to be connected to a high-voltage power supply to provide an electric field between the cathode and the anode to accelerate electrons emitted from the cathode toward the anode, and a current-density-profile control grid disposed between the anode and the cathode. The current-density-profile control grid is configured to provide an electron gun that produces an electron beam having a non-uniform current density profile. A method of producing a micro-device includes generating a beam of charged particles having a non-uniform charged-particle current density, illuminating a mask with the beam of charged particles, and exposing a workpiece with charged particles from the beam of charged particles.

摘要： It has been found that for a SCALPEL lithographic system thermal effects dictate that the acceleration voltage for the exposing electrons be maintained within a specific range. This range depends on a variety of factors but is generally in the 50 to 150 KeV region. Additionally, thermal considerations also dictate the method of scanning the mask to print an entire wafer.

摘要： Fabrication of submicron design rule large scale integrated circuits depends upon use of a strut-segmented mask with struts providing mechanical support to permit thinned mask segments consequently yielding improved resolution. "Stitching"--positioning of projected segment images to yield a satisfactory continuous image--is aided by lithographically defined skirts forming a continuous border within strut-supported segments.
