  • Patent number: 9577191
    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.

  • Patent number: 9502493
    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).

  • Patent number: 9435847
    Abstract: Methods for testing a special pattern and testing a probe card defect in wafer testing are provided. In the method for testing the special pattern, a wafer is divided into multiple testing partitions, in which each of the testing partitions includes multiple dies. The dies in each testing partition of the wafer are respectively tested by multiple sites of the probe card to obtain a testing map. Then, a number of the dies having defects and a number of the dies without defect within each of the testing partitions in the testing map are accumulated to construct chi-square test and calculate a maximum P-value. Finally, it is determined whether a minimum of the maximum P-values of all of the testing partitions is smaller than a certain predetermined threshold. If the minimum is smaller than the threshold, it is determined that the testing map of the wafer contains the special pattern.

The system includes a light source for generating a light beam, a wave-guide probe and an ultrasound receiving device. The wave-guide probe further has a reception portion and at least one transmission portion. The reception portion receives the light beam and then triggers a photoacoustic effect inside the reception portion so as thereby to generate at least one sound wave thereinside to be further transmitted to the at least one transmission portion. The transmission portion is merged into the organic medium. When the sound wave is transmitted to the transmission portion, an ultrasound area is generated inside the organic medium. The ultrasound receiving device is located adjacent to the organic medium, receives the ultrasound generated in the ultrasound area to form an ultrasound image of the organic medium, so as to achieve the imaging method.
