Abstract: A bonding tool includes a gas supply line that may extend directly between valves associated with one or more gas supply tanks and a processing chamber such that gas supply line is uninterrupted without any intervening valves or other types of structures that might otherwise cause a pressure buildup in the gas supply line between the processing chamber and the valves associated with the one or more gas supply tanks. The pressure in the gas supply line may be maintained at or near the pressure in the processing chamber so that gas provided to the processing chamber through the gas supply line does not cause a pressure imbalance in the processing chamber, which might otherwise cause early or premature contact between semiconductor substrates that are to be bonded in the processing chamber.

Abstract: A compressed sensing imaging method and a compressed sensing imaging system are provided. In the method, multiple grayscale masks having multiple elements with grayscale values represented by floating-point values or continuous values are generated as sensing matrices based on a compressed sensing theory. A spatial light modulator is controlled to modulate an electromagnetic wave projected on an object under test according to the grayscale value of each element in each grayscale mask, and a physical property of the electromagnetic wave passing through the object under test is detected to obtain multiple measured values. An image reconstruction algorithm is executed to reconstruct an image of the object under test by using the grayscale masks and the measured values obtained from the electromagnetic wave modulated by each grayscale mask.

Abstract: A sorted QR decomposition method used in a detection of a multiple input multiple output (MIMO) communication system is provided. First, whether a sorting-stop parameter of a channel transformation matrix of the MIMO communication system is greater than or equal to a sorting-stop threshold is determined. Then, whether energy of elements in a leftmost column within a process area of the channel transformation matrix is completely transferred to a top element in the leftmost column is determined. If the energy of the elements in the leftmost column within the process area is not yet completely transferred to the top element in the leftmost column, a unit process area of a process unit set is expanded.

Abstract: An image data decoding method of an image vertical blanking interval (VBI) and device thereof can adjust a run-in clock signal of data lines of teletext to a data phase of teletext data lines. The method can accurately decode data of the teletext data lines to avoid a phase bias and an erroneous decoding result. A main technical method to decode the data of the VBI is to extract the data of the teletext data lines to determine corresponding bit logical values of the image data and then to output a decode result and also output a phase adjustment value. The phase adjustment value is used to adjust a read phase value of the extracted image so as to synchronize a data phase in VBI.

Abstract: The present invention uses a 2D comb filter 20 to output a 2D chrominance signal C2d by comparing the current scan-line signals with the signals before and after the current scan-line signals. A 3D chrominance signal C3d is then acquired by directly subtracting two adjacent 2D image signals and then dividing by 2 to get an approximate chrominance signal C3d of the two 2D images. Ratio mixing is performed on the 2D chrominance signal C2d and the 3D chrominance signal C3d to output a near-actual chrominance signal. A chrominance variation value can be acquired by comparing the chrominance signals of the two adjacent images. Finally, an actual luminance signal of the current scan-line is separated by deducting the near-actual chrominance signal from the signals of the current scan-line to restore the luminance signal.

Abstract: A clamping system for clamping a video signal, wherein the clamping system uses a charge-pump unit in company with a digital clamping controller to clamp the potential of the video signal, prior to the video signal being input to a programmable gain amplifier and an A/D converter, so as to reach a desired level. The charge-pump unit provides two charge-pump circuits, wherein one charge-pump circuit supplies a strong burst to boost the potential of the video signal while the video signal is below a threshold value. Otherwise, the other charge-pump circuit supplies a weak burst to fine tune the potential of the video signal when the video signal has reached the threshold value.
