Abstract: A method of manufacturing a non-volatile semiconductor memory device begins by forming a dielectric layer pattern having an ONO composition on a substrate. A polysilicon layer is formed on the substrate including over the dielectric layer pattern. The polysilicon layer is patterned to form a split polysilicon layer pattern that exposes part of the dielectric layer pattern. The exposed dielectric layer is etched, and then impurities are implanted into portions of the substrate using the split polysilicon layer pattern as a mask to thereby form a source region having a vertical profile in the substrate.

Abstract: A method for assigning a channel in multi-FA CDMA mobile communication system according to the received power prevents communication quality of a FA from being inferior to that of the others by managing the interference level of the FA. The method comprises the steps of: comparing a first threshold value with received power when the base station receives a new call request; assigning a traffic channel in a first FA of the request, if the received power is less than the first threshold value, and searching a second FA of which received power is least, if not; comparing a second threshold value with the received power of the second FA; and assigning a traffic channel in the second FA if the received power is less than the second threshold value, and rejecting the request, if not.

Abstract: Disclosed herein is a protective net for vehicles, which includes a net part made of steel or stainless steel and a frame. When a driver or a passenger determines that the protective net is needed, the protective net constructed so that the net part made of steel or stainless steel is surrounded with the frame is used in place of a window inserted into a window frame of a vehicle.

Abstract: There are provided a nonvolatile memory device and a method of fabricating the same. A gate region of the nonvolatile memory device is formed as a stack structure including a tunnel oxide layer, a trapping layer, a blocking layer and a control gate electrode. The trapping layer is formed of a high-k dielectric having a higher dielectric constant than that of the tunnel oxide layer. When the trapping layer is formed of high-k dielectric, an EOT in a same thickness can be reduced, and excitation of electrons of the control gate electrode to the tunnel oxide layer due to a high potential barrier relative to the tunnel oxide layer is prevented so that program and erase voltages can be further reduced. As such, a problem that the tunnel oxide layer is damaged due to the conventional high program and erase voltages can be solved by reducing the program and erase voltages, and program and erase speeds of the transistor can be further improved.
