  • Publication number: 20090279040
    Abstract: A liquid crystal panel structure and a method for manufacturing the same are disclosed. The liquid crystal panel structure comprises a first substrate, a second substrate, a plurality of ball spacers, and a positioning structure. The second substrate is assembled parallel to the first substrate, and a gap is formed therebetween. The ball spacers are disposed in the gap to space the first substrate and the second substrate. The positioning structure is formed on one of the substrates and has a side collecting portion such that the ball spacers are moved to be located therein. The method for manufacturing the liquid crystal panel structure is to drop a solution which contains the ball spacers on the first substrate or the second substrate. Then, the ball spacers are positioned in the positioning structure after the solution is vaporized and a proper gap between the first and the second substrate is formed accordingly after assembly.

  • Publication number: 20080238346
    Abstract: A substrate splitting apparatus and a method for splitting a substrate using the substrate splitting apparatus are provided. The substrate splitting apparatus includes a servo motor, a transmission device, a substrate breaking bar, and a stage. One end of the transmission is directly or indirectly coupled to the servo motor while the other end is coupled with the breaking bar. The stage has a load-lock surface and the load-lock surface faces the breaking bar. The servo motor drives the transmission device to move the breaking bar toward the load-lock surface. A substrate with a pre-crack on the bottom is disposed on the load-lock surface. The servo motor drives the substrate breaking bar to move towards or away from the pre-crack. The method of splitting includes the following steps: forming a pre-crack on the substrate; controlling the servo motor to drive the breaking bar to move towards the substrate; and controlling the breaking bar to press the substrate at the pre-crack.

  • Publication number: 20080149174
    Abstract: A polymer solar cell and a manufacturing method thereof are disclosed. The cell includes a substrate, a first electrode located on top of the substrate, a conductive polymer layer having a conductive polymer and an additive located on the first electrode, a semiconductor layer over the conductive polymer layer and a second electrode over the semiconductor layer. The manufacturing method of the polymer solar cell is composed of following steps: growing a first electrode on a substrate; mixing an additive and a conductive polymer to form a mixture; depositing the mixture on the first electrode to form a conductive polymer layer; depositing a semiconductor layer on the conductive polymer layer and evaporating a second electrode on the semiconductor layer. By adding additive into the conductive polymer, resistance of the conductive polymer layer is reduced and efficiency of the cell is improved.
