  • Publication number: 20240094625
    Abstract: A method of making a semiconductor device includes forming at least one fiducial mark on a photomask. The method further includes defining a pattern including a plurality of sub-patterns on the photomask in a pattern region. The defining the pattern includes defining a first sub-pattern of the plurality of sub-patterns having a first spacing from a second sub-pattern of the plurality of sub-patterns, wherein the first spacing is different from a second spacing between the second sub-pattern and a third sub-pattern of the plurality of sub-patterns.

  • Publication number: 20240077804
    Abstract: A method includes forming a test pattern and a reference pattern in an absorption layer of a photomask structure. The test pattern has a first trench and a second trench, the reference pattern has a third trench and a fourth trench, the test pattern and the reference pattern have substantially the same dimension in a top view, and the second trench is deeper than the first trench, the third trench, and the fourth trench. The method further includes emitting a light beam to the test pattern to obtain a first interference pattern reflected from the test pattern, emitting the light beam to the reference pattern to obtain a second interference pattern reflected from the reference pattern; and comparing the first interference pattern with the second interference pattern to obtain a measured complex refractive index of the absorption layer.

  • 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.

  • Patent number: 9979778
    Abstract: A cloud data management method, an electronic apparatus and a cloud server are proposed. The method includes: executing an application launcher installed on the electronic apparatus to send a connection establishing request to the cloud server installed with an application; receiving a finishing command from the cloud server through a connection; and loading the application into a sandbox in the electronic apparatus through the application launcher in response to the finishing command, wherein the application is not installed on the electronic apparatus.

  • Patent number: 8520933
    Abstract: The present invention relates to methods for searching and constructing a 3D motif image database, wherein said 3D motif image database can be used to understand the connection relationship of a 3D network, e.g. a neural network comprising biological neural networks or artificial neural networks. The searching and constructing methods are applied on the 3D motif image database, a proper computer-aided graphic platform. The database not only facilitates the management of the huge amount of categorized data but also rationally excavates the hidden information cloaked within.

  • Patent number: 5299931
    Abstract: A barbecue stove includes a grill having transverse grill rods and longitudinal grill rods mounted on a rim placed on an upper portion of a stove body for barbecuing use, and a slide grating member slidably engageable with the grill rods normally shielding a charcoal-accessible opening cut out in the grill rods, whereby upon a sliding movement of the slide grating member to uncover the charcoal-accessible opening, new charcoal can be charged into the stove body through the opening or any tool can be inserted through the opening to condition the burning charcoal put on a charcoal grate at a lower portion in the stove body without removing the foods previously loaded on the slide grating member for convenient barbecuing purpose.
