摘要:
A method of manufacturing a high voltage device is described. A well region is formed within a substrate of a high voltage device region. A gate structure is made up of a gate oxide layer, a gate and an optional cap layer that are sequentially formed upon the well. Subsequently, using the gate structure as a mask, a large tilt angle light doping process is performed on the well of the high voltage device region of the well, thereby forming a lightly doped source and drain region. Thereupon, a optional thermal drive-in procedure is performed. Next, a spacer is formed on the side of the gate structure. Using the spacer and the gate structure as a mask, a heavy doping self-aligned ion implantation process is performed on the active region of the well, thereby forming a heavily doped source and drain region.

Various embodiments of a system and method for message-based purchasing are described. The system and method for message-based purchasing may include a message-based purchase service configured to determine that a selection has been performed through a network-based interface. Such selection may be indicative of one or more items offered for sale via the network-based interface. The message-based purchase service may be configured to, in response to the selection of one or more items, send to a communication device, a message indicating a code corresponding to the selection. The message-based purchase service may receive from the communication device through a communication channel that does not include the network-based interface, a message including the code. The message-based purchase service may be configured to, in response to determining that the message received from the communication device includes the code, generate a purchase request for the one or more previously selected items.

Item scarcity resulting from a high demand of the item is addressed by providing users a high demand sale process. In some aspects, users may opt-in to purchase the item in a sale by transmitting a mobile message to a host over a mobile device network prior to a sale of the item. If the user is eligible, the host then attempts to purchase the item on behalf of the user once the sale begins.

A HV MOS transistor device having a substrate, a gate, a source, a drain, a first ion well of a first conductive type disposed in the substrate, and a plurality of field plates disposed on the substrate is disclosed. The HV MOS transistor device further has a first doped region of a second conductive type positioned in the first ion well. Therefore, a first interface and a second interface between the first ion well and the first doped region are formed, and the first interface and the second interface are respectively positioned near the drain and the source. In addition, the first interface is positioned under a respective field plate to produce a smooth field distribution and to increase the breakdown voltage of the HV transistor device.

System and method for authorizing transactions, such as payments or money transfers. A transaction authorization mechanism may be provided through which a transaction initiated via a first communications channel may be authorized through a second, separate communications channel or mechanism. A source entity may initiate a transaction to a target entity via a first communications channel to a transaction authorization service. The transaction authorization service may confirm the transaction with the source entity via a second communications channel. Various embodiments may use different communications channels, for example conventional telephone systems, mobile/cellular phone systems, and text messaging systems as the first or second communications channels. After the transaction has been authorized via the second communications channel, the transaction authorization service and/or the source entity may contact the target entity to inform the target entity of the transaction. The target entity may then complete the transaction.

A project management system is enabled to implement filtering, sorting, and field level security for data associated with managed projects. A filter for field selection is prepared by a project client application and forwarded to a project server. The server generates an access attribute table based the user permissions that may be set for each field within the managed projects. Upon retrieving the selected fields from project database, the project server builds a secured list of fields. A data set to be provided to the project client is prepared by removing the fields for which the user lacks the requisite access permission prior to sorting the data. The removed data may be used for user-transparent computations within the project server, but guarded from client applications.

The present invention provides a non-volatile memory cell structure suitable for the flash memory cell and EEPROM cell (electrically erasable programmable read only memory cell) to perform the byte programming and byte erasing operations. In the programming operation, a higher negative voltage applied to the drain region, such that the hot holes is generated to induce the hot electrons into the floating gate through the tunneling oxide layer in the lateral electrical field. In addition, the gate voltage is around the threshold voltage, which dependent on the integration circuit device design. Furthermore, the non-volatile memory cell utilized the channel Fowler-Nordheim tunneling for erasing operation. In order to perform the byte erasing operation, the drain junction used as an inhibition switch. Thus, the unselected cell in the same word line is inhibited by biasing the drain to ground. Therefore, the word lines of unselected cells are grounded.
