Abstract:
A structure maintains a gap in a paper money discriminating apparatus that may be provided in an automatic teller machine. The structure may include a paper money discriminating sensor that is provided in an upper body to discriminate whether a paper money to be conveyed along a conveyance path is counterfeit money, a lower body that is provided so as to face the paper money discriminating sensor with a predetermined gap therebetween, and spacing protrusions that protrude upward from an upper surface of the lower body and come in contact with both end portions of the paper money discriminating sensor so as to maintain a constant gap between a lower surface of the paper money discriminating sensor and the upper surface of the lower body.
Abstract:
A method for providing a dual stress memory technique in a semiconductor device including an nFET and a PFET and a related structure are disclosed. One embodiment of the method includes forming a tensile stress layer over the nFET and a compressive stress layer over the pFET, annealing to memorize stress in the semiconductor device and removing the stress layers. The compressive stress layer may include a high stress silicon nitride deposited using a high density plasma (HDP) deposition method. The annealing step may include using a temperature of approximately 400-1200° C. The high stress compressive silicon nitride and/or the anneal temperatures ensure that the compressive stress memorization is retained in the pFET.
Abstract:
A bar type portable wireless terminal includes a lower body installed at its one side surface with a camera lens unit, and at the other surface an image reproduction device is adapted to output images captured by the camera lens unit, and an upper body coupled to an upper end of the lower body so that it is rotatable in a twisting direction relative to a rotation axis extending in a longitudinal direction of the lower body, the upper body being installed at its front surface with a display device adapted to enable the output of the images captured by the camera lens unit. The portable wireless terminal can be used as a digital image device and functions as portable phone, PDA and so on.
Abstract:
Disclosed is a method for forming a metal wiring in a semiconductor device in order to improve the operational speed of the semiconductor device. The method includes the steps of depositing an interlayer dielectric film on a silicon substrate, in which the interlayer dielectric film has a contact hole for exposing a predetermined portion of the silicon substrate, depositing a barrier layer on the interlayer dielectric film having the contact hole, depositing a first tungsten layer on the barrier layer by using SiH4 as a reaction gas, depositing a second tungsten layer on the first tungsten layer by using B2H6 as a reaction gas, depositing a third tungsten layer on the second tungsten layer in such a manner that the contact hole is filled with the third tungsten layer, and selectively etching the third tungsten layer, the second tungsten layer, the first tungsten layer, and the barrier layer, thereby forming the metal wiring.
