  • Publication number: 20170087587
    Abstract: A curing apparatus and a curing method are provided. The curing apparatus comprises: a chamber, configured for accommodating a substrate provided with a polyimide adhesive; an air extracting unit, configured for evacuating the chamber; and a heating unit, configured for performing a first heating on the substrate in the case that a first predetermined pressure is reached in the chamber during a evacuating process of the air extracting unit so as to remove organic gases from the polyimide adhesive, and performing a second heating on the substrate after the first heating so as to cure the polyimide adhesive.

  • Patent number: 9564354
    Abstract: The present invention discloses a via-hole etching method related to semiconductor manufacturing field, and the method overcomes the defects of an uncontrollable end point of a via-hole and an unfavorable profile-angle in a conventional via-hole etching method. The via-hole etching method includes: forming a structure for via-hole etching, includes: a low-temperature poly-silicon layer, a gate insulating layer, a gate metal layer and an interlayer insulating layer, which are sequentially formed on a substrate; forming a mask layer comprising a via-hole masking pattern on the structure for via-hole etching; by using a first etching process, etching the structure for via-hole etching to a first thickness of the gate insulating layer; by using a second etching process, etching the structure for via-hole etching to etch away the remaining thickness of the gate insulating layer, and uncovering the low-temperature poly-silicon layer; removing the mask layer to form a via-hole structure.

  • Publication number: 20110145025
    Abstract: A method of selecting at least one trip from a plurality of possible trips, each of the plurality of possible trips being for travel from an origin location and comprising stops at a plurality of destinations. The method is performed in computer apparatus configured to execute the method. The method comprises: determining a fare for each of a plurality of different leg options for each leg, each leg being between one of: the origin location and a destination; and two destinations; selecting a plurality of candidate leg options for each leg based on comparative amounts of the determined fares, the plurality of candidate leg options being fewer in number than the plurality of different leg options; and determining at least one trip based on the plurality of candidate leg options for each leg.
