  • Publication number: 20080074924
    Abstract: A memory cell that includes a control gate disposed laterally between two floating gates where each floating gate is capable of holding data. Each floating gate in a memory cell may be erased and programmed by applying a combination of voltages to diffusion regions, the control gate, and a well. A plurality of memory cells creates a memory string, and a memory array is formed from a plurality of memory strings arranged in rows and columns.

  • Publication number: 20070297246
    Abstract: In a memory cell array, each memory cell includes a control gate disposed laterally adjacent a floating gate. The memory cells in each memory column are disposed inside a single well. The control gate and the floating gate are disposed between two diffusion regions. Each memory cell may be erased and programmed by applying a combination of voltages to the diffusion regions, the control gate, and the well.

  • Publication number: 20070200163
    Abstract: A memory cell that includes two control gates disposed laterally between two floating gates where each floating gate is capable of holding data. The memory cell is formed by placing a first polysilicon on a substrate of semiconductor material, on which a well is placed. The control gates are preferably formed by a Damascene process, in which a first polysilicon is removed after forming two floating gates, and a second polysilicon is placed between these two floating gates. An anisotropic etching is later done on the second polysilicon to form two control gates.

  • Patent number: 6437365
    Abstract: An antifuse comprises a lower electrode formed from a metal layer in a microcircuit. A interlayer dielectric layer is disposed over the lower electrode and has an aperture formed therein. A conductive plug, formed from a material such as tungsten, is formed in the aperture. The upper surface of the interlayer dielectric is etched back to create a raised portion of the plug. The upper edges of the plug are rounded. An antifuse layer, preferably comprising a silicon nitride, amorphous silicon, silicon nitride sandwich incorporating a thin silicon dioxide layer above or below the amorphous silicon layer or such a sandwich structure covered by a titanium nitride layer, is disposed above the plug. An upper electrode, preferably comprising a metal layer is disposed over the antifuse layer.

  • Publication number: 20020047174
    Abstract: A semiconductor photodiode, method for optimizing its design, and method for generating a fast signal current in response to incident electromagnetic radiation. A component of the signal current associated with fast photo-generated electron-hole pairs (i.e., photocarriers) is included in the fast signal current, whereas a component of the signal current associated with the slow photocarriers is excluded. The invention is capable of data rates greater than 1 Gbit/s, is compatible with standard integrated circuit technology and processing techniques, and avoids the performance problems associated with a low data rate.

  • Patent number: 5592016
    Abstract: An antifuse comprises first and second electrodes separated by an antifuse material having a thickness selected to impart a desired target programming voltage to the antifuse. The antifuse material comprises a solid material stable at temperatures below about 600.degree. C., having a defect density less than about 100 defects/cm.sup.2, a breakdown field less than about 10 megavolts/cm, a dielectric constant lower than about 4.0, a resistivity of greater than about 10.sup.4 ohm-cm. The antifuse material may comprise organic materials such as polyimides compatible with high-temperature processes including cured polyamic acids, pre-imidazed polymers, photo-sensitive polyimides, and other polimides such as pyralin, probimide, PIQ, etc. The antifuse materials of the present invention also include fluorinated polymers having very low dielectric constants, such as teflon, paralines, polyphenylquinoxaline, benzocyclobutene polymers, and perfluoropolymers.
