    摘要： Cleaning in periodic acid (H.sub.5 IO.sub.6) aqueous solutions (HI solutions) of particular compositions removes thermally unstable hydrocarbons from the surfaces of semiconductor wafers and enables the direct bonding of semiconductor surfaces such that the bonded interface between these surfaces remains free of bubbles even after heating subsequent to bonding.

    摘要： The method is for identifying a signal and its image signal input to the heterodyne frequency sweep system. Comparing to a traditional heterodyne frequency sweep technology, a mixing module with a positive and negative sign filters (PNS filters) is introduced, and the detection and identification module is added, and the typical low-pass filter in the input module is removed. According to the timing order sequence of the signal output from the intermediate frequency (IF) filter and PNS filters, a signal and its image signal can be identified. The bandwidth of the heterodyne frequency sweep system is not limited by the cut-off frequency of the low-pass filter (LPF) of the traditional heterodyne frequency sweep system.
