  • Publication number: 20140001523
    Abstract: A method of preparing an active pixel cell on a substrate includes exerting a first stress on the substrate by forming a shallow trench isolation (STI) structure in the substrate. The method further includes testing the stressed substrate using Raman spectroscopy at a plurality of locations on the stress substrate. The method further includes depositing a stress layer having a second stress on the substrate. The stress layer covers devices of the active pixel cell that are on the substrate and the devices include a photodiode next to the STI and a transistor, and the deposition of the stress layer results in the second stress being exerted on the substrate, the second stress countering the first stress.

  • Publication number: 20130333049
    Abstract: A data protection method for a portable electronic device and a computer program product for the same are applicable to a portable electronic device operating on a Linux operating system. A storage region of the portable electronic device is partitioned to provide a specific partition for storing data to be protected. The specific partition will be mounted, and the data to be protected will be displayed, only if the data to be protected contains an execution command, otherwise the specific partition will be unmounted. Hence, the specific partition is only available when it is confirmed that the data to be protected contains an execution command. Accordingly, unspecific commands, such as file browsing, cannot enable the mounting of the specific partition, thereby hiding the specific partition and enhancing the security of the data to be protected.

  • Patent number: 8581127
    Abstract: A key structure includes a keycap, a scissors-type connecting element, a membrane module, a light-emitting element and a base plate. The light-emitting element is used for emitting light beams. The keycap has a protrusion structure for blocking the light beams and preventing the light beams from leaking out through the gap between said keycap and said base plate. The base plate has a slot corresponding to the protrusion structure. When the keycap is depressed, the membrane module is pressed by the protrusion structure to be subject to deformation, so that a deformed part of the membrane module is inserted into the slot of the base plate. In such way, the hand feel of depressing the keycap is not adversely affected.
