  • Publication number: 20240069431
    Abstract: In a method of manufacturing an attenuated phase shift mask, a photo resist pattern is formed over a mask blank. The mask blank includes a transparent substrate, an etch stop layer on the transparent substrate, a phase shift material layer on the etch stop layer, a hard mask layer on the phase shift material layer and an intermediate layer on the hard mask layer. The intermediate layer is patterned by using the photo resist pattern as an etching mask, the hard mask layer is patterned by using the patterned intermediate layer as an etching mask, and the phase shift material layer is patterned by using the patterned hard mask layer as an etching mask. The intermediate layer includes at least one of a transition metal, a transition metal alloy, or a silicon containing material, and the hard mask layer is made of a different material than the intermediate layer.

  • Publication number: 20200360969
    Abstract: A coffee bean sorting system has a feeding mechanism, a rotary disk, at least one image capture device, an information processing device, and a removal mechanism. The rotary disk can receive coffee beans transported from the feeding mechanism, and can rotate along an axis thereof, such that the coffee beans are spaced apart from each other and form a succession. The image capture device can capture an initial image of each of the coffee beans. The information processing device can perform machine learning training or deep learning training function, identify each of the initial images, and after determining a coffee bean is non-conforming, make the removal mechanism to remove the non-conforming coffee bean.

  • Patent number: 9766286
    Abstract: A method for diagnosing a defect is provided. A first candidate pair comprises a first defect candidate and a second defect candidate. A first pattern is generated to distinguish one or more faults of the first defect candidate from one or more faults of the second defect candidate. The first defect candidate is removed responsive to determining that the first pattern does not detect the first defect candidate and determining that an automatic test equipment (ATE) failure log associates the first pattern with failure. Removing the first candidate pair, as well as additional candidate pairs when possible, promotes diagnosis efficiency by reducing a number of computations required.

  • Patent number: 9704595
    Abstract: Techniques are provided for non-volatile storage self-detecting that a heating event has occurred to the non-volatile storage. One example of the heating event is an Infrared (IR) reflow process. In one aspect, a block of memory cells in a memory device are put through a number of program/erase cycles. A group of the memory cells in the cycled block are programmed to a reference threshold voltage distribution. Some time may pass after programming the cycled block. The memory device self-detects that there has been a heating event in response to a shift in the reference VT distribution being more than an allowed amount. The memory device may switch from a first programming mode to a second programming mode in response to detecting that the heating event has occurred.
