Patent Summary

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

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 197: Having insulated gate (e.g., IGFET, MISFET, MOSFET, etc.)
Subclass 239: Capacitor
Subclass 396: Stacked capacitor

Class 257: Active Solid-State Devices (E.G., Transistors, Solid-State Diodes)

This class provides for active solid-state electronic devices, that is, electronic devices or components that are made up primarily of solid materials, usually semiconductors, which operate by the movement of charge carriers - electrons or holes - which undergo energy level changes within the material and can modify an input voltage to achieve rectification, amplification, or switching action, and are not classified elsewhere.

Subclass 295: With ferroelectric material layer
Subclass 417: Strain sensors
Subclass E29.003: Characterized by their crystalline structure (e.g., polycrystalline, cubic) particular orientation of crystalline planes (EPO)
Subclass E29.071: Quantum box or quantum dot structures (EPO)
Subclass E29.322: Single electron transistors: Coulomb blockade device (EPO)
Subclass E29.324: Controllable by variation of applied mechanical force (e.g., of pressure) (EPO)

Class 423: Chemistry Of Inorganic Compounds

This class provides for what is generally termed the field of inorganic chemistry. It includes inorganic compounds, nonmetallic elements and processes of producing the same involving a chemical reaction. The products are generally in a relatively pure state but may be a mixture with no other utility than as a source material for an inorganic compound or element. This includes metal compound products useful in metallurgical processes of obtaining free metals.

Subclass 337: By oxidizing volatile silicon compound (e.g., combustion, etc.)
Subclass 445R: Elemental carbon
Subclass 447.7: In specific atmosphere (other than vacuum or air)
Subclass 445B: Fullerene (e.g., C60, C70, etc.)
Subclass 610: Titanium dioxide
Subclass 613: Reacting with oxiding gas
Subclass 618: Group IVA metal (Ge, Sn, or Pb)
Subclass 625: Aluminum

Class 106: Compositions: Coating Or Plastic

This class is the broad generic class for: (1) Coating, impregnating or plastic compositions, especially those which set or harden to retain a given shape. Most of the compositions herein found are those which are capable of undergoing a change from a fluent to a nonfluent condition, or from a solid noncoherent form to a solid coherent form. (2) Materials or ingredients, not in themselves coating, for use in such compositions and for which there is no provision elsewhere. (3) This class takes processes for preparing or making the compositions, materials, or ingredients classified herein, which processes are classified with the corresponding composition, material or ingredient. (4) This class does not include patents which are limited to apparatus only.

Subclass 437: Oxidation of titanium tetrahalide or product

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 225: Metal coating

Class 252: Compositions

(A) Compositions of matter, having or not having structure, physical form or heterogeneous arrangement of components and for which there is no provision elsewhere. (B) Packages of such compositions, or other articles which include such compositions for which there is no provision elsewhere. (C) Processes of making, or peculiar to making, such compositions and for which there is no provision elsewhere. (D) Apparatus for use in or peculiar to such processes and for which there is no provision elsewhere.

Subclass 502: Elemental carbon containing
Subclass 510: With organic component
Subclass 511: Resin, rubber, or derivative thereof containing
