    Abstract: A method of forming complex three-dimensional microstructures wherein an external stimulus is applied to a first layer of a photosensitive material, thereby creating voids in the first layer, and any material present in those voids is removed. A sacrificial material is then provided within at least a portion of the voids. This sacrificial layer fills the voids, either in whole or in part, and enables a second layer of photosensitive material to be stacked upon the first, while still preserving the pattern formed in the first layer. Once the sacrificial layer has been applied, a second layer of photosensitive material may then be stacked onto the first. Successive layers of photosensitive material and sacrificial material may be added until a final, complex three-dimensional structure is created. The sacrificial material may then be removed with a solvent such as carbon dioxide.

    Abstract: A method for forming a microstructure includes photolithographically forming a vertically extending post on a portion of a surface of a substrate to provide a first structure. A flowable, sacrificial material is deposited over a surface of the first structure. The flowable, sacrificial materially flows off the top surface and sidewall portions of the post onto adjacent portions of the surface of the substrate to provide a second structure. A non-sacrificial material is deposited over a surface of the second structure. The non-sacrificial material is deposited to conform to the surface of the second structure. The non-sacrificial is deposited over the sacrificial material, over the sidewall portions and over the top surface of the post. The deposited sacrificial material is selectively removed while the non-sacrificial material remains to form a third structure with a horizontal member provided by the non-sacrificial material. The horizontal member is supported a predetermined distance above the surface of the substrate by a lower portion of the post. The flowable material is a flowable oxide, for example, hydrogensilsesquioxane glass, and the post has a width less than 20 .mu.m. The resulting structure, formed with a single photolithographic step, is used for supporting a capacitor deposited over it. The capacitor is formed as a sequence of deposition steps; i.e., depositing a first conductive layer over a surface of the support structure; depositing a dielectric layer over the conductive layer; and depositing a second conductive layer over the dielectric layer.

    Abstract: A method for making patterns on the surface of a substrate by graphoepitaxy, includes depositing a layer of resin on the surface of the substrate; making patterns in the resin on the surface of a substrate; curing the patterns in the resin by producing a layer of amorphous carbon on the surface of the patterns in the resin; depositing a layer of statistical copolymer after curing the patterns in the resin; grafting the layer of statistical copolymer onto the patterns in the resin by annealing; and depositing a layer of a block copolymer into the spaces defined by the patterns in the resin after curing the patterns and the grafting of the layer of statistical copolymer.
