Latest Patents

Xinping Deng holds a patent for a wafer cleaning apparatus. This invention comprises a rotary shaft with a chuck designed to retain the wafer securely. A fixed shaft is coaxially passed through the rotary shaft, and both upper and lower end covers block the top and bottom of the fixed shaft. The fixed shaft is a hollow structure featuring at least one circle of exhaust holes on its wall. The lower end cover includes a gas inlet port that allows a protective gas to enter the interior of the fixed shaft. This protective gas creates positive pressure in the annular space between the fixed shaft and the rotary shaft, effectively preventing contaminants from diffusing to the back side of the wafer. This innovative design significantly improves the cleanliness of the wafer after the cleaning process.
