Abstract: Provided is a fluorine-doped tin oxide support, a platinum catalyst for a fuel cell having the same, and a method for producing the same. Also described is a high electrical conductivity and electrochemical durability by doping fluorine to the tin oxide-based support through an electrospinning process. Thus, while resolving a degradation issue of the carbon support in the conventional commercially available platinum/carbon (Pt/C) catalyst, what is designed is to minimize an electrochemical elution of dopant or tin, which is a limitation of the tin oxide support itself and has excellent performance as a catalyst for a fuel cell.

Abstract: Disclosed is a display device. In accordance with the display device, before an organic stack of a light-emitting diode is formed, a sticker is attached to a substrate, while a camera hole-forming portion and a margin area around the same are present, to form the organic stack, and the sticker and components on top of the sticker, such as the organic stack, are removed, so that the edge of the organic stack can be aligned without any additional process using separate masks and the reliability of the display device can be improved due to the provision of the organic stack at a location spaced apart from the camera hole by the margin area.

Abstract: A semiconductor device includes at least two die stacked on and electrically coupled to an underlying buffer die, which includes a delay control circuit therein. The delay control circuit is configured to: (i) receive and selectively delay test inputs for testing the at least two die, and (ii) transfer test inputs and a delayed version of the test inputs to a first one of the at least two die and a second one of the at least two die, respectively, during test mode operation. The at least two die may include a vertical stack of N (N>2) die on the buffer die and the delay control circuit may include a timing control circuit therein that is configured to supply test inputs to each of the N die in a staged manner so that commencement of respective test modes within each of the N die using the test inputs are out-of-sync relative to each other.
