Embodiment Construction

[0024] Extremely small and well defined structures, for example of inorganic particles, can be formed in association with a surface using self-assembly approaches. Nanoparticles with very uniform sizes are preferred components for forming self-assembled structures, although other functional compositions can be used. The nanoparticles are organized into a well defined structures using fabrication techniques that take advantage of molecular recognition characteristics of self-assembly approaches. Molecular recognition can involve various interactions, such as commingling, key-lock relationships and guest-host interactions.

[0025] The deposition techniques are combined with localization techniques that constrain the resulting structures within isolated islands along the substrate surface. The islands can be ordered or disordered arrays. The organized structures or islands are suitable for the production of microelectronics and the like, which incorporate well defined miniature componen...

Abstract

A material includes a layer with a plurality of self-assembled structures comprising compositions. The structures are localized in separate islands covering a portion of the layer in an integrated assembly. In some embodiments, the compositions include nanoparticles. In particular, some embodiments pertain to a material with a self-assembled formation of inorganic particles with an average diameter less than about 100 nm. The structures can be used as devices within an integrated article. The method for producing the articles comprises a localization process defining boundaries of the devices and a self-assembly process within the identified boundaries.

Description

CROSS REFERENCE TO RELATED APPLICATIONS [0001] This application is a divisional of copending U.S. patent application Ser. No. 09 / 558,266 filed Apr. 25, 2000 to Kambe et al., entitled “Self-Assembled Structures,” incorporated herein by reference.BACKGROUND OF THE INVENTION [0002] The invention relates to small scale structures forming devices with application, for example, to microelectronics. In particular, the invention relates to self-assembled structures on and / or within a surface of a material structure. [0003] Advances in a variety of fields have created a demand for many types of new materials. In particular, a variety of chemical powders can be used in many different processing contexts. Specifically, chemical powders can be used in the production of electronic devices, such as flat panel displays, electronic circuits and photonic crystals. [0004] Similarly, technological advances have increased the demand for improved material processing with strict tolerances on processing ...
