  • Publication number: 20220302315
    Abstract: The various described embodiments provide a transistor with a negative capacitance, and a method of creating the same. The transistor includes a gate structure having a ferroelectric layer. The ferroelectric layer is formed by forming a thick ferroelectric film, annealing the ferroelectric film to have a desired phase, and thinning the ferroelectric film to a desired thickness of the ferroelectric layer. This process ensures that the ferroelectric layer will have ferroelectric properties regardless of its thickness.

  • Publication number: 20220207012
    Abstract: A method for processing data, applied in an electronic device, obtains dimensions of a target data set by dimensionality reduction processing, and creates a search index based on the target data set. A denominator d of a noise ratio is set. An unlabeled data point P is selected from the target data set, and neighbors of the data point P are searched for according to the search index to obtain a neighbor data set. A number of data in the neighbor data set of a type which is different from type of the data point P is calculated, the calculated number is set to be a numerator c of the noise ratio. The noise ratio A=c/d is calculated, and if greater than a preset noise ratio, the data point P is labeled as noise data. The present disclosure shortens the time of processing training data.
