A handoff method in a wireless local area network (WLAN) and an apparatus using the same are provided. A mobile station (MS) switches between a data transceiving mode and a probing mode at a predefined interval when the MS is transmitting/receiving packages. In the probing mode, the MS probes one or more channels each time and selects an access point (AP) for handoff from the probing result according to a predetermined rule, so as to re-establish a network connection.

A six mask-steps method for fabricating liquid crystal display is described. A driving area and a pixel area are defined by a first mask step. Gates on the driving/pixel area and upper electrodes of capacitors on the pixel area are defined by a second mask step. Then, using the gates and the upper electrodes as a mask, a source/drain, channel region and lower electrode are formed in the driving/pixel area by an ion-doping process. A second insulation layer is formed and covers the insulation substrate. A plurality of first openings is formed by the third mask step and the gate and the source/drain are exposed. A second conductive layer is formed and covers the second insulation layer and the first opening is filled. Then, the second conductive layer is patterned, and a source/drain line is formed and contacts electrically with the source/drain by the fourth mask step. A dielectric layer is formed and covers the second insulation layer and the second conductive layer; the dielectric layer has a planar surface. A second opening is formed by the fifth mask step and the drain line on the pixel area is exposed. Finally, a pixel electrode is defined by the sixth mask step and contacts electrically with the drain line.

Circuitry formed at a surface of a substrate includes first and second lines in first and second layers of the circuitry. The first line includes semiconductor material and extends between first and second connecting points at which it connects electrically to other components. The second line is connected to receive a gate signal, and crosses the first line in two or more channel regions. The first line includes a channel in each channel region, and the channels are in series. The second line conducts the gate signal to all of the channel regions. The first line includes charge carrier sources and destinations positioned so that conductivity of the first line between the first and second connecting points is controlled by the gate signal. The first layer can be polysilicon, and the second layer can be polysilicon or metal. The first line can be undoped in the channel regions but heavily doped in other areas. Each of the first and second lines can include an angle of approximately 90.degree. between two of the channel regions, forming a Crossed-L configuration. In an active matrix display or other array with M scan lines and N data lines, the first line can be connected to the nth data line and the second line can receive the gate signal from the mth scan line.

Array circuitry formed at a surface of a substrate includes a first conductive layer with M scan lines, a second conductive layer with N data lines, and cell circuitry for a region in which the mth scan line and the nth data line cross. The cell circuitry includes a component with a data lead for receiving signals from or providing signals to the nth data line. A first semiconductor layer of the cell circuitry includes a first line with a channel between a connecting point to the nth data line and a connecting point to the component's data lead. A second semiconductor layer includes a second line extending from a connecting point to the mth scan line and crossing the first line at the channel. The first and second conductive layers and the cell circuitry are formed with electrical connections at the connecting points so that signals on the mth scan line control conductivity of the first line between the nth data line and the data lead. The semiconductor layers can be polysilicon. The first semiconductor layer can be formed before the second, with the first line electrically connected to the data lead by implanting a dopant. The connections to the mth scan line and the nth data line can be metal/semiconductor interfaces, with the first conductive layer deposited on the second line and with the second conductive layer deposited on the first line through an opening in an insulating layer.
摘要:
A thin film SOI CMOS device wherein the suitably doped deposited layers of an n-channel transistor and a p-channel transistor are simultaneously deposited. The source and drain elements of one transistor and the gate element of the other transistor are formed in a lower, highly doped, semiconductor layer and are separated from the corresponding gate element and source and drain elements formed in an upper, highly doped, semiconductor layer. The layer levels are separated by two intrinsic or lightly doped semiconductor layers sandwiching a dielectric layer, so that the intrinsic or lightly doped semiconductor layer lying contiguous to the source and drain elements serves as an active channel layer and the intrinsic or lightly doped semiconductor layer lying contiguous to the gate element serves to extend the gate layer.
