  • RRAM CELL BOTTOM ELECTRODE FORMATION
    Publication number: 20150287918
    Abstract: The present disclosure relates to a method of forming a resistive random access memory (RRAM) cell having a reduced leakage current, and an associated apparatus. In some embodiments, the method is performed by forming a bottom electrode over a lower metal interconnect layer using an atomic layer deposition (ALD) process to form at least a top portion of the bottom electrode. A dielectric data storage layer is formed onto the top portion of the bottom electrode in-situ with forming the top portion of the bottom electrode. A top electrode is formed over the dielectric data storage layer, and an upper metal interconnect layer is formed over the top electrode. By forming the top portion of the bottom electrode using an ALD process that is in-situ with the formation of the overlying dielectric data storage layer, leakage current, leakage current distribution and device yield of the RRAM cell are improved.

  • Signal processing apparatus and associated method
    Patent number: 9131198
    Abstract: A signal processing apparatus includes an initial detecting module, a mixer, a symbol rate detecting module, a judging module and a correcting module. The initial detecting module determines an initial carrier frequency offset of an input signal according to a spectrum of the input signal. The mixer adjusts the input signal according to the initial carrier frequency offset to generate a frequency-compensated signal. The symbol rate detecting module determines a symbol rate of the input signal. The judging module judges whether the initial carrier frequency offset is correct according to the frequency-compensated signal. When a judgment result of the judging module is negative, the correcting module determines a corrected carrier frequency offset according to the symbol rate and the spectrum.

  • MULTI-STEP METHOD OF FORMING A METAL FILM
    Publication number: 20150243730
    Abstract: The present disclosure relates to an integrated chip having a titanium nitride film that provides for a reduced leakage path, and an associated method of formation. In some embodiments, the integrated chip comprises a semiconductor substrate. A titanium nitride film is disposed over the semiconductor substrate. The titanium nitride film comprises a plurality of titanium nitride layers having grain boundaries abutting vertical column-like structures of titanium nitride. The grain boundaries are discontinuous between a top surface of the titanium nitride film and a bottom surface of the titanium nitride film. The discontinuity of the grain boundaries between the different titanium nitride layers reduces leakage paths through the titanium nitride film (e.g., and thereby can improve operation of a MIM capacitor having titanium nitride electrodes).
