Abstract: An apparatus and method for processing a substrate can reduce the concentration of process by-products in a chemical solution.

Abstract: In one example, a semiconductor device can comprise a substrate, a device stack, first and second internal interconnects, and an encapsulant. The substrate can comprise a first and second substrate sides opposite each other, a substrate outer sidewall between the first substrate side and the second substrate side, and a substrate inner sidewall defining a cavity between the first substrate side and the second substrate side. The device stack can be in the cavity and can comprise a first electronic device, and a second electronic device stacked on the first electronic device. The first internal interconnect can be coupled to the substrate and the device stack. The encapsulant can cover the substrate inner sidewall and the device stack and can fill the cavity. Other examples and related methods are disclosed herein.

Abstract: The present invention may provide an organic electroluminescent device which exhibits low driving voltage as well as high efficiency by including an electron transporting layer material having an improved electron transporting ability.

Abstract: The present invention dicloses a bag for a mobile user. A bag for a mobile device user according to the present invention comprises a body having a front side, a back side, lateral sides, a top side, and a bottom side; a support board being placed on the front side; a first multi-position fixing unit being pivotally provided to the lateral sides or the front side; a second multi-position fixing unit being provided to both sides, a bottom side, or an outer side of the support board, and being pivotally combined with the support board; and a support arm in which one end of the support arm is pivotally combined with the first multi-position fixing unit, while the other end of the support arm is pivotally combined with the second multi-position fixing unit, wherein a position of the second multi-position fixing unit is adjusted by a rotational movement of the first multi-position fixing unit, and a tilting angle of the support board is adjusted by a rotational movement of the second multi-position fixing unit.

Abstract: The present invention discloses a back pack for a mobile device user. A back pack for a mobile device user according to the present invention comprises a body; a support board adjacently facing a front side of the body in parallel; a hinge, being provided on the front side or on a lateral side of the body, for pivotally coupling the support board and the body; and a multiple positioning fix unit to fix the support board at an open position, wherein the support board is pivotally coupled to the body by the hinge and the multiple positioning fix unit so as to adjust an open angle of the support board.
