Patent Summary

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

Class 365: Static Information Storage And Retrieval

Apparatus or corresponding processes for the static storage and retrieval of information. For classification herein, the storage system must be (1) static, (2) a singular storage element or plural elements of the same type, (3) addressable.

Subclass 185.05: Particular connection
Subclass 185.06: Segregated columns
Subclass 185.27: Substrate bias
Subclass 185.28: Tunnel programming
Subclass 149: Capacitors

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 E27.103: Electrically programmable ROM (EPO)
Subclass E29.129: Gate electrodes for transistors with floating gate (EPO)
Subclass E21.209: Making electrode structure comprising conductor-insulator-conuctor-insulator-semiconductor, e.g., gate stack for non-volatile memory (EPO)
Subclass E21.422: With floating gate (EPO)

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 119: Electrically conductive adhesive
Subclass 200: And additional electrical device
Subclass 201: Including insulated gate field effect transistor having gate surrounded by dielectric (i.e., floating gate)
Subclass 257: Having additional gate electrode surrounded by dielectric (i.e., floating gate)
Subclass 258: Including additional field effect transistor (e.g., sense or access transistor, etc.)
Subclass 266: Having additional, nonmemory control electrode or channel portion (e.g., for accessing field effect transistor structure, etc.)
Subclass 275: Making plural insulated gate field effect transistors of differing electrical characteristics
Subclass 276: Introducing a dopant into the channel region of selected transistors
