摘要:
The present invention provides a system for treating wastewater produced during grinding and slicing in a semiconductor packaging process, comprising a collecting tank for collecting the wastewater produced during grinding and/or slicing in a semiconductor packaging process; a physical filtration device for separating the suspended materials from the wastewater by physical filtration, the physical filtration device being in fluid communication with the collecting tank; a receiving device for receiving the wastewater treated by the physical filtration device, and the receiving device being in fluid communication with the physical filtration device. The present invention further provides a method for treating wastewater produce during grinding and slicing in a semiconductor packaging process. The present invention simplifies the treatment of wastewater produced during grinding and slicing in a semiconductor packaging process, and lowers the cost.
摘要:
A method for processing integrated circuit devices including a water recycling process. The method includes operating a chemical mechanical planarization process, which includes a discharge for process water. The process water is used to process one or more semiconductor wafers. The method also selectively discharges process water from the discharge. A step of transferring the process water from the chemical mechanical planarization process to a facility process is included. The method then uses the discharged water in the facility process.
