  • Publication number: 20210028331
    Abstract: A protection layer for use in fabrication of failure analysis (FA) sample is disclosed, which principally comprises a first thin film, a buffer thin film and a second thin film By forming the protection layer on a surface of a malfunction device die, a FA sample of the malfunction device die is obtained. As a result, in the case of treating the sample with a FIB thinning process, there are no cracks, distortion, and/or collapse resulted from inter-elemental isobaric interferences, stress effect or charge accumulation occurring on the surface layer of the malfunction device die because of the protection of the protection layer. On the other hand, this protection layer can also be applied to a microLED element or a VCSEL element, so as to make microLED element and the VCSEL element possess excellent stress withstanding capability.

  • Patent number: 10896488
    Abstract: A method for removing haze from an image is provided. The image is converted to S(x) and V(x), the S(X) is saturation component of the image, and the V(x) is value component of the image. The S(x) is filtered to obtain S?(x), and the V(x) is filtered to obtain V?(x). A depth d(x) is estimated by calculating a difference between the S?(x) and V?(x). Once a transmission map t(x) is calculated based on the d(x), haze is removed from the image based on the transmission map t(x).

  • Publication number: 20200153615
    Abstract: A method for a node to issue a new block is used for a distributed system in which transactions and records are organized in block. The method comprises the steps of: determining a value R from a common reference string; computing a value s associated to a value of a status with a private key at a node, wherein the private key is a private signing key corresponding to the node, and the value s can only be computed by the node with the private key; computing a value r by taking the value s into a function H at the node, wherein the value r is unpredictable and unique to other nodes; and determining whether the node obtains a right to issue a new block by taking the values R and r into a function V.
