    摘要: A method and apparatus for profiling and identifying the source of a signal is provided. A first method includes receiving a signal produced by a known source and creating a matrix of wavelet coefficients corresponding to a wavelet transform of the signal. The method also includes profiling the signal according to an output of a wavelet transform utilizing a particular base function and a particular scale set. A second method includes performing a wavelet transform having a particular profile on a received signal and determining the presence of a particular signal-producing entity as a function of wavelet coefficients exceeding a threshold. An apparatus includes a receiver configured to receive a signal and a processor coupled to the receiver, such that the processor is configured to perform wavelet transforms on the signals. A database is coupled to the processor and configured to store wavelet transform profiles.

In various embodiments, the process may include removing material from the fin semiconductor to achieve a thinned semiconductor fin, which has receded beneath the shadow of the laterally receded mask. Electronic devices may include the thinned semiconductor fin as part of a semiconductor device.

    摘要: Some embodiments include methods of forming vertical transistors. A construction may have a plurality of spaced apart fins extending upwardly from a semiconductor substrate. Each of the fins may have vertical transistor pillars, and each of the vertical transistor pillars may have a bottom source/drain region location, a channel region location over the bottom source/drain region location, and a top source/drain region location over the channel region location. Electrically conductive gate material may be formed along the fins while using oxide within spaces along the bottoms of the fins to offset the electrically conductive gate material to be above the bottom source/drain region locations of the vertical transistor pillars. The oxide may be an oxide which etches at a rate of at least about 100 Å/minute with dilute HF at room temperature. In some embodiments the oxide may be removed after the electrically conductive gate material is formed.
