  • Publication number: 20210407737
    Abstract: Disclosed herein is an electronic component that includes a substrate, a planarizing layer covering a surface of the substrate, a first conductive layer formed on the planarizing layer and having a lower electrode, a dielectric film made of a material different from that of the planarizing layer and covering the planarizing layer and first conductive layer, an upper electrode laminated on the lower electrode through the dielectric film, and a first insulating layer covering the first conductive layer, dielectric film, and upper electrode. An outer periphery of the first insulating layer directly contacts the planarizing layer without an intervention of the dielectric film.

  • Patent number: 8599357
    Abstract: A photolithography system has at least one spatial light modulator, a scanning mechanism configured to move an exposure area relative to a target object in a scanning direction, a plurality of memories (1st to Nth memories), a data processor, and exposure controller. The exposure area is defined as a projection area of the spatial light modulator. The plurality of memories corresponds to a plurality of partial exposure areas that is defined by dividing the exposure area. The data processor successively writes exposure data into each memory in accordance with the timing of an exposure, and the exposure controller controls the plurality of light modulating elements on the basis of the relative position of the exposure area. The data processor writes newly generated exposure data into the first memory, and shifts exposure data stored in the 1st to (N?1)st memories to the 2nd to Nth memories, respectively.

  • Patent number: 8510456
    Abstract: In a connection device connected to a network mounted in a boat, a protocol of a connection device connected to a network mounted in a boat is identified based on a communication ID in a certain message transmitted through the network. A device protocol is determined in accordance with the protocol of the network. Data communication in the network is performed in conformity with the device protocol. Accordingly, when the connection device is connected to the network, the connection device automatically identifies a protocol of the network and operates appropriately. Therefore, upward compatibility is maintained and usability is improved.

  • Patent number: 8307216
    Abstract: In a device authentication control method and device, when a connection device is connected to a network mounted on a boat, it is determined whether or not the connection device corresponds to an authentication-free device. If the connection device does not correspond to an authentication-free device, an authenticating action is performed on the connection device. If the connection device does correspond to an authentication-free device, the connection device is exempted from the authenticating action. In this way, when a connection device does not correspond to an authentication-free device, an authenticating action is performed, but when the connection device corresponds to an authentication-free device, the connection device is exempted from an authenticating action. As a result, it is possible to handle specific connection devices as authentication-free.

  • Patent number: 7979153
    Abstract: An exposure-data generating apparatus comprises a first memory, a second memory, and an exposure data memory. The first memory stores drawing data in bitmap format as first data that is used for an exposure. The second memory stores second data whose data unit in a column direction is converted to a resolution unit of information of each cell based on the first data. The exposure data memory stores exposure data that is raster data obtained by a burst transfer of third data at every column unit. The second data is rearranged and converted to the third data, where an arrangement of data of each cell of the second data in the column direction is changed to a row direction. The cell constitutes a display element of a Digital Micro-mirror Device that performs the exposure based on said exposure data.
