A method and system for placing an order to purchase an item via the Internet. The order is placed by a purchaser at a client system and received by a server system. The server system receives purchaser information including identification of the purchaser, payment information, and shipment information from the client system. The server system then assigns a client identifier to the client system and associates the assigned client identifier with the received purchaser information. The server system sends to the client system the assigned client identifier and an HTML document identifying the item and including an order button. The client system receives and stores the assigned client identifier and receives and displays the HTML document. In response to the selection of the order button, the client system sends to the server system a request to purchase the identified item. The server system receives the request and combines the purchaser information associated with the client identifier of the client system to generate an order to purchase the item in accordance with the billing and shipment information whereby the purchaser effects the ordering of the product by selection of the order button.

In this paper, recent progress of phase change memory (PCM) is reviewed. The electrical and thermal properties of phase change materials are surveyed with a focus on the scalability of the materials and their impact on device design. Innovations in the device structure, memory cell selector, and strategies for achieving multibit operation and 3-D, multilayer high-density memory arrays are described. The scaling properties of PCM are illustrated with recent experimental results using special device test structures and novel material synthesis. Factors affecting the reliability of PCM are discussed.

A very high density field programmable memory is disclosed. An array is formed vertically above a substrate using several layers, each layer of which includes vertically fabricated memory cells. The cell in an N level array may be formed with N+1 masking steps plus masking steps needed for contacts. Maximum use of self alignment techniques minimizes photolithographic limitations. In one embodiment the peripheral circuits are formed in a silicon substrate and an N level array is fabricated above the substrate.

A process for forming low resistance contacts between silicide areas and upper level polysilicon interconnect layers including a specific doping technique that provides solid low resistance contacts between a lower level of a silicided area and an upper level polysilicon interconnect. The doping technique combines a doping implant of the upper level polysilicon and an ion-mixing implant into a single implant thereby achieving a low resistive implant which also reduces processing steps.

A one-time, voltage-programmable, logic element has an antifuse element constructed within a trench etched in a silicon substrate. A sidewall of the trench abuts a diffusion region. The trench is lined with a nitride dielectric layer, which is in turn covered by polycrystalline silicon. The polycrystalline silicon serves as a voltage reference line. In a preferred embodiment, the diffusion region forms a first source/drain region of a field-effect transistor. In order to program the element, a voltage sufficient to rupture the nitride dielectric layer is applied between the diffusion region and the reference line. The transistor is utilized to isolate a particular logic element from other logic elements.

To identify an RFID tag in a field of RFID tags, an interrogator sends a series of commands to implement an arbitration scheme. The commands include differentiation, selection, and modulation information. The tag uses the differentiation information to differentiate commands sent by the interrogator from commands sent by other interrogators that may be within communication range of the tag. The selection information is used by the tag to determine if the tag is a member of a group selected by the interrogator for response to the interrogator. If the tag is a member of the selected group, the tag may send a reply that is modulated using a modulation type selected by the modulation information. In accordance with one of the modulation types, one of three different pulse waveforms is selected by the interrogator via the modulation information to multiply with the baseband waveform of the reply from the tag.

A CMOS integrated circuit such as a DRAM is fabricated, in which a first layer of polysilicon is used to form transistor gates, and capacitor cell plates are formed from a second polysilicon layer. N-wells are first formed, followed by initial oxide. The application of the CMOS process to the reverse poly technique provides enhanced alignment of critical transistor gates and permits the use of less mask steps in fabricating the CMOS circuit.

Reverse polysilicon CMOS fabrication

Described herein is a reference voltage circuit which includes, in combination, a bit line and first and second word line reference transistors connected to the bit line and operative to be turned on with a reference pulse simultaneously with the turning on of the word lines in the main memory circuit. First and second ferroelectric capacitors are connected to each of the first and second word line reference transistors, respectively, and to a source of plate line switching voltage, and a first precharging transistor is connected between the first ferroelectric capacitor and ground potential. A second precharging transistor is connected between the second ferroelectric capacitor and a further source of switching voltage, so that the first and second ferroelectric capacitors are polarized in a ONE and ZERO state in the manner identical to the logic states of the ferroelectric capacitors in the main ferroelectric memory circuit. Thus, when the first and second word line reference transistors turn on, the bit line reference voltage is raised above ground potential by the sum of the voltages of the first and second ferroelectric capacitors. This in turn causes the bit line reference voltage, BL, to track the voltage variations of the ferroelectric capacitors in the main memory circuit, thus providing improved margins for the BL and BL complementary signals which are sensed by a plurality of sense amplifiers for the main memory circuit.
