Abstract: A touch panel includes: a transparent rigid window screen having an inner surface and an outer surface that is adapted to be touched by a user; and a touch sensor module secured to the inner surface of the transparent rigid window screen for detecting at least one touch position of the user's touch on the outer surface. The outer surface of the transparent rigid window screen is formed with an antireflection layer that includes a plurality of protruding pillars protruding outwardly from the outer surface and arranged to take a form of a quasicrystalline pattern having a plurality of pattern sections that are collectively ordered but not periodic.

Abstract: A method of stabilizing an anti-reflection coating (ARC) layer is disclosed. The method provides a substrate with a dielectric layer, a conductive layer, and the ARC layer formed thereon. The ARC layer is treated in an alloy treatment step prior to forming a photoresist layer over the ARC layer, so that the specificity of the ARC layer is stabilized to allow accurate transfer of a desired pattern. A photomask with the desired pattern is provided, while a photolithographic process is then performed to transfer the pattern onto the wafer.

Abstract: A method of stabilizing an anti-reflection coating (ARC) layer is disclosed. The method provides a substrate with a dielectric layer, a conductive layer, and the ARC layer formed thereon. The ARC layer is treated in an ultraviolet (UV) curing step prior to forming a photoresist layer over the ARC layer, so that the specificity of the ARC layer is stabilized to allow an accurate pattern is replicated in the photoresist layer. A photomask with the desired pattern is provided, while a photolithographic process is then performed to transfer the pattern onto the wafer.

Abstract: A method of fabricating shallow trench isolations (STI) which forms a substrate with a patterned first oxide layer and a patterned silicon nitride layer thereon, so that active regions are defined with openings formed between the active regions. The openings are then over etched to form trenches for fabricating the STI, followed by forming a second oxide layer that conforms to a profile of the trenches. A third oxide layer is globally formed over the second oxide layer, sidewalls of the first oxide layer, and the silicon nitride layer. A thermal process is performed to densify a portion of the third oxide layer, so that a top portion of the third oxide layer is harder than a lower portion of the third oxide layer. The excessive portion of the third oxide layer above the silicon nitride layer is removed by performing chemical mechanical polishing, which planarizes a top surface of the third oxide layer in order to complete the manufacture of the STI.

Abstract: A process for manufacturing a thin film transistor for use in a CMOS SRAM circuit is described. A key feature is the formation of two different photoresist masks from the same optical mask. The first photoresist mask is generated using a normal amount of actinic radiation during exposure and is used to protect the gate region during source and drain formation through ion implantation. The second photoresist mask is aligned relative to the gate in exactly the same orientation as the first mask but is given a reduced exposure of actinic radiation. This results, after development, in a slightly larger mask which is used during etching to form the oxide cap that will protect the channel area during the subsequent silicidation step. Making the cap slightly wider than the channel ensures that small lengths of the source and the drain regions that abut the channel are not converted to silicide. Thus, the finished device continues to act as a thin film transistor, but has greatly reduced source and drain resistances.

Abstract: A method for fabricating thin film transistors (TFTS) for SRAM devices is described having metal shields over the channel regions for improved electrical characteristics. The method involves forming N.sup.+ doped polysilicon TFT gate electrodes having a gate oxide thereon. An N.sup.- doped amorphous silicon is deposited and recrystallized. The recrystallized silicon is P.sup.+ doped to form the TFT source/drain areas and patterned to form the N.sup.- doped channel regions with P.sup.+ source/drain areas. After depositing an insulating layer, a metal layer is deposited and patterned to completely cover and shield the TFT channel regions from ion damage during the plasma hydrogenation which is subsequently performed. The patterned metal layer also serves as the bit lines for the SRAM device. The plasma hydrogenation reduces the surface states at the gate oxide channel interface, while the shielding effect of the metal layer from ion damaging radiation reduces the off current (I.sub.off), increases the I.sub.

Abstract: A process is provided in which silicon thin film transistors fabricated with polycrystalline silicon, silicon oxide, and silicon conductive layers are exposed to microwave plasmas containing water vapor and to subsequent annealing steps to bring about an improvement in the ratio of device drain current in the conductive state to that in the non-conductive state, and a lower device subthreshold voltage swing.
