  • Patent number: 8298892
    Abstract: A fabricating method of an insulator for replacing a gate structure in a substrate by the insulator. The fabricating method includes the step of providing a substrate including a first buried gate structure. The first buried structure includes a first trench embedded in the substrate and a first gate filling in the first trench. The first trench has a first depth. Then, the first gate of the first buried structure is removed. Later, the substrate under the first trench is etched to elongate the depth of the first trench from the first depth to a third depth. Finally, an insulating material fills in the first trench with the third depth to form an insulator of the present invention.

  • Publication number: 20110217799
    Abstract: A method for the separation of multiple dies during semiconductor fabrication is described. On an upper surface of a semiconductor wafer containing multiple dies, metal layers are deposited everywhere except where a block of stop electroplating material exists. The stop electroplating material is obliterated, and a barrier layer is formed above the entire remaining structure. A sacrificial metal element is added above the barrier layer, and then the substrate is removed. After the semiconductor material between the individual dies is eradicated, any desired bonding pads and patterned circuitry are added to the semiconductor surface opposite the sacrificial metal element, a passivation layer is added to this surface, and then the sacrificial metal element is removed. Tape is added to the now exposed barrier layer, the passivation layer is removed, the resulting structure is flipped over, and the tape is expanded to separate the individual dies.
