Abstract: Disclosed is a meta-structure. The meta-structure includes a lower electrode, a lower insulating layer on the lower electrode, a lower metal oxide layer on the lower insulating layer, a metal layer on the lower metal oxide layer, an upper metal oxide layer on the metal layer, an upper insulating layer on the upper metal oxide layer, and antenna electrodes on the upper insulating layer.

Abstract: A complementary thin film transistor (TFT) includes a substrate and a first TFT and a second TFT disposed on the substrate, wherein a first conductive semiconductor layer of the first TFT and a second gate electrode layer of the second TFT are disposed in the same layer and include the same material.

Abstract: Disclosed is a design code pattern capable of utilizing the elements having a freedom degree of a design and an aesthetic value in a design side by storing information of a suitable size in consideration of characteristics where a large amount of information is not required to connect with a target server by a gateway. The coded information is expressed as the design patterns including a plurality of design individuals wherein the number and order are applied to the design individuals on the basis of sizes and shapes of the designs.

Abstract: A method for providing a service uses a consumer's used product as advertisement media through a digital code allowing exposers and recognizers of the digital code to achieve profit from advertisement. When a Web server selling an article receives a purchase request for the article having a predetermined digital code, the Web server compensates the purchaser and/or a third person, and receives a compensated amount from an advertiser as a terminal used by the purchaser/third person recognizes the digital code added to the article and notifies the Web server. As the purchaser selects the digital code to be carved on the article, the purchaser makes an advertisement instead of the advertiser, and receives in return a reduction in the purchase price and compensation. The Web server can lower the price of the article in return for selling the article with the digital code, or benefit the purchaser through compensation.

Abstract: A boat for a vertical diffusion furnace has an upper disk and a lower disk spaced parallel from each other by a predetermined distance. A pair of first bars, having a plurality of wafer holding slots, face each other along a first center plane extending along a diameter of the upper and lower disks, and connect the upper and lower disks. A pair of second bars also connect the upper and lower disks, and are positioned at a predetermined angle with respect to a second center plane orthogonal to the first center plane. The second bars have a plurality of slots corresponding to the slots of the first bars. A pair of first auxiliary bars are installed adjacent to the pair of first bars to also connect the upper and lower disks. The boat may further have a pair of second auxiliary bars for connecting the upper and lower disks at positions adjacent to the pair of second bars. Also, a pair of horizontal supporting bars connect the first auxiliary bars to the second auxiliary bars.
