  • Publication number: 20150079806
    Abstract: A method includes rotating a wafer at a first speed for a first time duration. The wafer is rotated at a second speed that is lower than the first speed for a second time duration after the first time duration. The wafer is rotated at a third speed that is higher than the second speed for a third time duration after the second time duration. A photoresist is dispensed on the wafer during the first time duration and at least a portion of a time interval that includes the second time duration and the third time duration.

  • Publication number: 20140268449
    Abstract: A device includes a first power node, a second power node, a first input node, a second input node, a protected circuit, and a switch circuit. The protected circuit is coupled between the first power node and the second power node, and the protected circuit is further coupled with the second input node. The switch circuit is coupled with the first power node, the second power node, the first input node, and the second input node. The switch circuit is configured to electrically decouple the first input node and the second input node after (a) the first power node is floating or electrically coupled to the second power node and (b) a voltage level at the first input node is greater than a voltage level at the second power node by a predetermined voltage value.

  • Patent number: 8803186
    Abstract: An LED substrate structure has a substrate and a conducting portion. The substrate has a bottom surface and two opposite first lateral surfaces connected with the bottom surface. The bottom surface has the conducting portion formed thereon, and the conducting portion has a first cutting segment located on a contact border defined between one of the two first lateral surfaces and the bottom surface. The conducting portion further has an expansion region connected with the first cutting segment. The length of the first cutting segment is shorter than any segment taken on the expansion region parallel thereto.

  • Patent number: 7968875
    Abstract: An organic photosensitive optoelectronic device includes an anode, an organic photosensitive layer formed on the anode and having a donor portion and an acceptor portion, a hole blocking layer formed on the organic photosensitive layer so as for the organic photosensitive layer to be sandwiched between the anode and the hole blocking layer, and a cathode formed on the hole blocking layer so as for the hole blocking layer to be sandwiched between the cathode and the organic photosensitive layer. The highest occupied molecular orbitals (HOMO) of the hole blocking layer is at least 0.3 eV higher than that of the donor portion. Therefore, the optoelectronic device efficiently suppresses dark current so as to enhance sensitivity when applied to a detector.
