Abstract: A touch panel includes a transparent substrate, a first pattern/layer on the transparent substrate, and an second pattern/layer on or under the first pattern/layer. The first pattern/layer includes first electrodes detecting a first coordinate value and first metal interconnections connecting the first electrodes to a flexible printed circuit board (FPCB). The second pattern/layer includes second electrodes detecting a second coordinate value and second metal interconnections connecting the second electrodes to the FPCB. The first and second metal interconnections extend on side and back surfaces of the transparent electrode. Therefore, the metal interconnections connect the first and second patterns/layers to the FPCB by being formed on the side and back surfaces of the transparent substrate, which reduces the length and/or width of the bezel (a non-active region).

Abstract: Methods of forming integrated circuit memory devices, such as DRAM memory cells, include the steps of simultaneously forming storage electrode and bit line contact regions of first conductivity type in a semiconductor region of second conductivity type. The contact regions preferably receive a double dose of first conductivity type dopants. This double dose compensates for etching damage caused during processing and improves the memory cell's refresh characteristics. The preferred methods of forming DRAM memory cells include the steps of forming an electrically insulating layer on a face of a semiconductor substrate containing a region of second conductivity type therein (e.g., P-type) extending to the face, and then forming a word line (or segment thereof) on the electrically insulating layer, opposite the region of second conductivity type.

Abstract: Methods of forming semiconductor devices containing field oxide and channel-stop isolation regions therein include the steps of forming a plurality of first channel-stop isolation regions by implanting first conductivity type impurities at a first dose level into a face of a semiconductor substrate and then forming respective field oxide isolation regions at the locations where the first channel-stop isolation regions have been implanted. A conductive layer, which contacts active regions of the substrate and covers the field oxide isolation regions, is then patterned over the field oxide isolation regions to expose central portions of the upper surfaces of the field oxide isolation regions.
