The present invention related to a semiconductor wafer cleaning system comprising a preliminary cleaning station for removing particles on a wafer in advance by spraying deionized water thereon; a first cleaning station for cleaning remaining particles firstly by rotating frictionally a pair of brushes disposed to be contacted with a front surface and a back surface of the wafer and by spraying chemicals thereon through a chemical sprayer being provided independently; a first rinsing station for rinsing by spraying a cleaning liquid onto the firstly cleaned wafer at the first cleaning station; a second cleaning station for cleaning particles secondly remained on the front surface and the back surface of the wafer by spraying the chemicals onto the firstly rinsed cleaned wafer at the first rinsing station through a chemical sprayer being provided independently using the same structure and manner as those of the first cleaning station; a second rinsing station for rinsing by spraying the cleaning liquid onto the secondly cleaned wafer at the second cleaning station; and a dry station for drying the remained cleaning liquid using centrifugal force generated by rotating the rinsed wafer at the second rinsing station at a high speed. According to the present invention, a waiting time of entry into each cleaning station is minimized by processing a cleaning operation and a rinsing operation of a surface-polished wafer in a cleaning station and a rinsing station which are provided separately and independently thereby improves wafer productivity significantly by solving a delayed phenomenon in a whole process of wafer manufacturing.

The present invention relates to an atmosphere water vapor measurement method based on a Beidou satellite. Signals of the Beidou satellite generate delay phenomena when the signals pass through the atmosphere, the delay can be divided into ionosphere delay, static delay and wet zenith delay. With adopting a dual-frequency receiving technology, the ionosphere delay can be almost completely eliminated, and the static delay can be corrected to the millimeter magnitude, such that the wet zenith delay with the millimeter magnitude is obtained. The wet zenith delay and the total amount of the water vapor have a strict direct proportion relationship, such that the water vapor content of the atmosphere can be accurately inverted by using the following characteristic of the signals of the Beidou satellite: when the signals emitted by the Beidou satellite pass through the atmosphere with the different water contents, the different delay phenomena appear. With the technology of the present invention, the technological monopoly of the developed countries is broken, the application blank of the Beidou satellite in our country is filled, and the high-technology and low-cost precision measurement method is provided for meterorology monitoring and forecasting in our country, such that the Beidou satellite navigation system becomes the important means for accurate weather forecasting in our country, wherein the developed countries adopt GPS to carry out the precise water vapor measurement.

The invention discloses a method and electronic equipment for processing video frame data, aiming to solve the technical problem that a delay phenomenon occurs when a call is made between video call equipment with different video frame data processing capabilities and the picture delay is caused in the prior art. The method includes the following steps: acquiring current video frame data accordingto a target frame frequency rate, and obtaining a first acquisition time of starting to acquire the current video frame data, wherein the target frame frequency is a frame frequency supported by equipment with the lowest rate of processing the video frame data in first electronic equipment and at least one second electronic equipment, and the data is processed according to the processing speed ofthe target frame frequency; calculating a first time difference based on the first acquisition time and the start time of starting to encode the previous video frame data; judging whether the first time difference is greater than a processing duration corresponding to the target frame frequency; and if so, encoding the current video frame data and transmitting the data to the at least one secondelectronic equipment.

The invention claims a switch circuit capable of quickly discharging transistor parasitic capacitance charge. The switch circuit comprises a transistor connected with the load; the input end of the transistor is connected with a charge discharging circuit; the charge discharging circuit receives a second controlling signal provided by the external device for discharging the charge on the transistor parasitic capacitance under the action of the second controlling signal, and lowering the potential on the input end of the transistor to the reference potential. At the same time, the invention also discloses the charge discharging method of the switch circuit. The switch circuit provided by the invention can effectively eliminate the delay phenomenon when starting up the load through quickly regulating the potential on the input end of the transistor down by utilizing the charge discharging circuit in the transitional stage of turning from on to off, thus greatly reducing the time cost wasted on reducing the virtual high potential of the input end after the transistor is on.
