    Abstract: A method of forming an integrated circuit structure on a wafer includes providing a first etcher comprising a first electrostatic chuck (ESC); placing the wafer on the first ESC; and forming a via opening in the wafer using the first etcher. After the step of forming the via opening, a first reverse de-chuck voltage is applied to the first ESC to release the wafer. The method further includes placing the wafer on a second ESC of a second etcher; and performing an etching step to form an additional opening in the wafer using the second etcher. After the step of forming the additional opening, a second reverse de-chuck voltage is applied to the second ESC to release the wafer. The second reverse de-chuck voltage is different from the first reverse de-chuck voltage.

    Abstract: Diffusion barrier layer is required during copper metallization in IC processing to prevent Cu from diffusion into the contacting silicon material and reacting to form copper silicide, which consumes Cu and deteriorates electrical conduction. With decreasing feature sizes of IC devices, such as those smaller than 90 nano-meter (nm), the thickness of diffusion barrier layer must be thinner than 10 nm. For example, a thickness of 2 nm will be called for at the feature size 27 nm. Disclosed in the present invention is ultra-thin barrier materials and structures based on tantalum silicon carbide, and its composite with another metallic layer Ru film. The retarding temperature, by which no evidence of copper diffusion can be identified, is 600˜850° C. depending on thickness, composition and film structure, at a thickness 1.6˜5 nm.

    Abstract: A directional antenna including a ground plane, a feeding element and a radiating element is provided. The feeding element is adjacent to the ground plane and includes a feeding point. A coupling gap is formed between the radiating element and the feeding element, and the radiating element includes a coupling point. Both the coupling point of the radiating element and the feeding point of the feeding element are at the perpendicular line of a ground plane. Further, a distance between the coupling point and an open end of the radiating element is smaller than 0.16λ of a resonant frequency of the directional antenna.
