Provided is a probe card. The probe card includes a ceramic substrate including a signal line, and a plurality of probe pins formed on the ceramic substrate, and including probe bodies having one end connected to the signal line and probe tips formed at other end of the probe body. The probe body is divided into a first section adjacent to the signal line and second section adjacent the probe tips. The first section is united by an insulating support, and the second sections are divergently arranged to position the probe tips at different measurement regions, respectively.

Disclosed is a differential capacitive type MEMS sensor apparatus provided with a MEMS structure including a differential capacitive type MEMS sensor and a capacitance compensator having a MEMS structure. The differential capacitive type MEMS sensor apparatus includes a fixed frame unit including first and second fixed frames prepared in pairs, partially fixed to the MEMS base; a movable frame unit movably connected to the MEMS base substrate so that first capacitance is generated between the movable frame unit and the first fixed frame and second capacitance is generated between the movable frame unit and the second fixed frame; first capacitance compensating frame units serving to compensate for the first capacitance using capacitances generated between the movable frames and the movable electrodes; and second capacitance compensating frame units serving to compensate for the second capacitance using capacitances generated between the movable frames and the movable electrodes.

Provided is a method of manufacturing a ceramic probe card. A ceramic laminated body having a plurality of ceramic green sheets and an interlayer circuit including a conductive via and a conductive line formed in the plurality of ceramic green sheets is prepared. Then, at least one probe pin structure connected to the interlayer circuit is formed by selectively removing the plurality of photosensitive ceramic sheets having a ceramic powder and a photosensitive organic component on the ceramic laminated body necessarily, and by filling a metal material in a region from which the plurality of photosensitive ceramic sheets have been removed. Then, a ceramic substrate having the at least one probe pin structure is provided by simultaneously firing the ceramic laminated body and the photosensitive ceramic sheets, and by removing the photosensitive ceramic sheets.

Disclosed herein is a resistive touch screen, including: a large-area touch screen formed by connecting two or more single touch screens, each including a first substrate and a second substrate which are respectively coated with transparent electrodes on one side thereof and face each other, on the same level; a plurality of first dot spacers formed on first connection parts at which the first substrates are connected with each other and supporting second connection parts at which the second substrates are connected with each other; and a plurality of second dot spacers formed on respective one sides of the first substrates excluding the first connection parts and having a lower height than the plurality of first dot spacers. The resistive touch screen is advantageous in that a large-area touch panel can be realized by connecting single touch panels on the same level.

Disclosed is a touch screen input device, which includes a window plate through which a signal is input, a conductive film applied on one surface of the window plate using a conductive polymer, a first adhesive layer applied on one surface of the conductive film, and an anti-noise film applied on one surface of the first adhesive layer using a conductive polymer and thus grounded, so that the conductive film is directly applied on the window plate, thus omitting bonding of an additional film coated with a conductive film to the window plate, thereby preventing the generation of foam and simplifying the manufacturing process. A method of manufacturing the touch screen input device is also provided.

An organic conductive composition and a touch panel input device are provided. The organic conductive composition includes a conductive polymer, a dopant lowering electric resistance, an acrylic binder, and a viscosity control agent. The organic conductive composition has excellent transparency, low surface resistance, similar elongation and thermal expansion coefficient to that of a substrate. Accordingly, a conductive film of the touch panel input device including the organic conductive composition is not likely to be peeled off from the substrate, which makes it possible to increase the durability of the input device.
