  • Patent number: 9178006
    Abstract: A method for reducing the leakage current in DRAM MIM capacitors comprises forming a multi-layer dielectric stack from an amorphous highly doped material, an amorphous high band gap material, and a lightly-doped or non-doped material. The highly doped material will remain amorphous (<30% crystalline) after an anneal step. The high band gap material will remain amorphous (<30% crystalline) after an anneal step. The lightly-doped or non-doped material will become crystalline (?30% crystalline) after an anneal step. The high band gap material is formed between the amorphous highly doped material and the lightly or non-doped material and provides an intermediate barrier to conduction through the multi-layer dielectric stack.

  • Patent number: 8880217
    Abstract: A picking system includes a conveyer, a robot, a main camera, and a control device. The conveyer conveys workpieces. The robot performs a holding operation and a moving operation on the workpieces. The main camera captures the transport path of the conveyer. The control device detects the workpiece on the basis of the image captured by the main camera and instructs the robot to perform the holding operation on the detected workpiece. Moreover, the control device instructs the robot to perform the holding operation on the overlapped workpieces when the overlapping of the workpieces is detected.

  • Patent number: 8546236
    Abstract: A method for fabricating a DRAM capacitor stack is described wherein the dielectric material is a multi-layer stack formed from a highly-doped material combined with a lightly or non-doped material. The highly-doped material remains amorphous with a crystalline content of less than 30% after an annealing step. The lightly or non-doped material becomes crystalline with a crystalline content of equal to or greater than 30% after an annealing step. The dielectric multi-layer stack maintains a high k-value while minimizing the leakage current and the EOT value.
