    摘要: A novel reversal lithography process without etch back is described. The reversal material comprises nanoparticles that are selectively deposited into the gaps between features without overcoating the tops of the features. As a result, a patterned imaging layer can be removed using solvent, blanket exposure followed by developer washing, or dry etching directly, without an etch-back process, and the original bright field lithography pattern can be reversed into dark field features, and transferred into subsequent layers using the nanoparticle reversal material as an etch mask.

    摘要: This invention provides methods of creating via or trench structures on a developer-soluble hardmask layer using a multiple exposure-development process. The hardmask layer is patterned while the imaging layer is developed. After the imaging layer is stripped using organic solvents, the same hardmask can be further patterned using subsequent exposure-development processes. Eventually, the pattern can be transferred to the substrate using an etching process.

    摘要: Radiation-sensitive sol-gel compositions are provided, along with methods of forming microelectronic structures and the structures thus formed. The compositions comprise a sol-gel compound and a base generator dispersed or dissolved in a solvent system. The sol-gel compound comprises recurring monomeric units comprising silicon with crosslinkable moieties bonded to the silicon. Upon exposure to radiation, the base generator generates a strong base, which crosslinks the sol-gel compound in the compositions to yield a crosslinked layer that is insoluble in developers or solvents. The unexposed portions of the layer can be removed to yield a patterned sol-gel layer. The invention can be used to form patterns from sol-gel materials comprising features having feature sizes of less than about 1 μm.

    摘要: New temporary bonding methods and articles formed from those methods are provided. The methods comprise bonding a device wafer to a carrier wafer or substrate only at their outer perimeters in order to assist in protecting the device wafer and its device sites during subsequent processing and handling. The edge bonds formed by this method are chemically and thermally resistant, but can also be softened, dissolved, or mechanically disrupted to allow the wafers to be easily separated with very low forces and at or near room temperature at the appropriate stage in the fabrication process.

The compositions comprise an organometallic oligomer and an organic polymer or oligomer dispersed or dissolved in a solvent system. The compositions have long shelf lives and can be prepared by easy and reliable preparation procedures. The compositions can be cured to cause conversion of the composition into films of metal oxide interdispersed with organic polymer or oligomer. The cured films have high refractive indices, high optical clarities, and good mechanical stabilities at film thicknesses of greater than about 1 μm.

    摘要: Novel compositions and methods of using those compositions to form high refractive index coatings are provided. The compositions preferably comprise both a reactive solvent and a high refractive index compound. Preferred reactive solvents include aromatic resins that are functionalized with one or more reactive groups (e.g., epoxides, vinyl ethers, oxetane), while preferred high refractive index compounds include aromatic epoxides, vinyl ethers, oxetanes, phenols, and thiols. An acid or crosslinking catalyst is preferably also included. The inventive compositions are stable under ambient conditions and can be applied to a substrate to form a layer and cured via light and/or heat application. The cured layers have high refractive indices and light transmissions.
