Abstract
A slurry dispense system utilizes a buffer chamber to release the pressure from the supply pump, and buffer the irregular flow rate of the supply pump. It also utilizes a positive displacement pump to control the dispense flow. With the help of the buffer chamber, the positive displacement pump is able to provide a constant flow rate, and can be accurately controlled. A high resolution and a high speed can be achieved at the same time.
Claims22
A slurry dispense system, comprising:
- a slurry supply component comprising a supply pump and a pipe to transport said slurry;
- a buffer chamber comprising an inlet communicatively connected with said pipe to receive said slurry from said slurry supply component to maintain a predetermined range of volume of slurry in said buffer chamber, a release opening releasing pressure from said slurry supply component, and an outlet to displace said slurry;
- and
- a flow control dispenser communicatively connected with said outlet of said buffer chamber to dispense said slurry at a controlled flow rate.
