Patent Summary

U.S. Patent Classes & Classifications Covered in this listing:

Class 427: Coating Processes

This is the generic class for: A. applying or obtaining a coating on a surface. The coating may be hard or soft, permanent or transitory, supplied solely by extraneous materials or supplied wholly or in part by the base material. B. impregnating a base by causing a coating material to extend or penetrate into the base material, or into the interstices of a porous, cellular or foraminous material. C. taking preparatory treatments of the base material, subsequent treatments of the coated base material and other ancillary noncoating operations claimed, per se, processes limited to etching for making a base more compatible with, or adherent to, the coating wherein the base is the substrate (work) onto which a coating is applied are included.

Subclass 255.11: Base includes an inorganic compound containing silicon or metal (e.g., glass, ceramic, brick, etc.)
Subclass 255.18: Silicon containing coating
Subclass 255.394: Nitrogen containing coating (e.g., metal nitride, etc.)

Class 438: Semiconductor Device Manufacturing: Process

This class provides for manufacturing a semiconductor containing a solid-state device for the following purposes: (a) conducting or modifying an electrical current, (b) storing electrical energy for subsequent discharge within a microelectronic integrated circuit, or (c) converting electromagnetic wave energy to electrical energy or electrical energy to electromagnetic energy. Also operations involving: (1) coating a substrate with a semiconductive material, or (2) coating a semiconductive substrate or substrate containing a semiconductive region. It also provides for operations involving etching a semiconductive substrate or etching a substrate containing a semiconductive region. The class provides for packaging or treatment of packaged semiconductor.

Subclass 230: Utilizing gate sidewall structure
Subclass 488: Polycrystalline semiconductor

Class 977: Nanotechnology

This art collection provides for disclosures related to: nanostructure and chemical compositions of nanostructure; device that include at least one nanostructure; mathematical algorithms, e.g., computer software, etc., specifically adapted for modeling configurations or properties of nanostructure; methods or apparatus for making, detecting, analyzing, or treating nanostructure; and specified particular uses of nanostructure. the term "nanostructure" is defined to mean an atomic, molecular, or macromolecular structure that: has at least one physical dimension of approximately 1-100 nanometers; and possesses a special property, provides a special function, or produces a special effect that is uniquely attributable to the structure s nanoscale physical size.

Subclass 814: Group IV based elements and compounds (e.g., CxSiyGez, porous silicon, etc.)
