  • Patent number: 6836468
    Abstract: A radio frequency identification device comprises an integrated circuit including a receiver, a transmitter, and a microprocessor. The receiver and transmitter together define an active transponder. The integrated circuit is preferably a monolithic single die integrated circuit including the receiver, the transmitter, and the microprocessor. Because the device includes an active transponder, instead of a transponder which relies on magnetic coupling for power, the device has a much greater range.

  • Patent number: 6825109
    Abstract: A method for electrically linking the contacts of a semiconductor device to their corresponding digit lines includes disposing a quantity of mask material into a trench through which the contact is exposed. The mask also abuts a connect region of a conductive element of a corresponding conductive line and, therefore, protrudes somewhat over a surface of the semiconductor device. A layer of insulative material is formed over the semiconductor device with the mask exposed therethrough. The mask is then removed, leaving open cavities, including the trench and a strap region continuous with both the trench and a connect region of the corresponding conductive line. Conductive material is introduced into each open cavity to define conductive plugs or studs and conductive straps that are electrically isolated from one another. Semiconductor devices including features that have been fabricated in accordance with the method are also within the scope of the present invention.

  • Publication number: 20040224464
    Abstract: A method of making a vertical diode is provided, the vertical dioxide having associated therewith a diode opening extending through an insulation layer and contacting an active region on a silicon wafer. A titanium silicide layer covers the interior surface of the diode opening and contacts the active region. The diode opening is initially filled with an amorphous silicon plug that is doped during deposition and subsequently recrystallized to form large grain polysilicon. The silicon plug has a top portion that is heavily doped with a first type dopant and a bottom portion that is lightly doped with a second type dopant. The top portion is bounded by the bottom portion so as not to contact the titanium silicide layer. For one embodiment of the vertical diode, a programmable resistor contacts the top portion of the silicon plug and a metal line contacts the programmable resistor.

  • Publication number: 20040222445
    Abstract: In an aspect, an apparatus is provided that sets and reprograms the state of programmable devices. In an aspect, a method is provided such that an opening is formed through a dielectric exposing a contact formed on a substrate. The resistivity of the contact is modified by at least one of implanting ions into the contact, depositing a material on the contact, and treating the contact with plasma. In an aspect, a spacer is formed within the opening and programmable material is formed within the opening and on the modified contact. A conductor is formed on the programmable material and the contact transmits to a signal line.
