How to Clean the Dust and Dirt on the Surface of Sputtering Target?

We can see that there are many kinds of sputtering targets, and the application scope and direction are also vast, but we do not elaborate them here. Here we discuss the cleaning of sputtering targets.

 

In the process of using the sputtering target, there may be dust or dirt in the target. There may be many reasons, such as not using vacuum packaging, not wearing gloves before use, more dust in storage or use space. So, when we encounter dust or dirt on the target surface, what should we do? How to clean it is safer?

 

Here we need to pay attention to a problem: Different materials and cleaning methods. Next, the we analyzes from two aspects: Pure metal target and ceramic target: How to clean the target surface correctly?

Step 1: Clean with a soft lint-free cloth soaked in acetone.

Step 2: Clean with alcohol.

Step 3: Clean with deionized water.

Step 4: After cleaning with deionized water, place the target in the oven and dry at 100 ℃ for 30 minutes.

Step 1: Clean with "lint-free cloth".

Step 2: After removing the dirty area, flush the target with argon with high pressure and low water, to remove all foreign particles that may cause arcing in the sputtering system.
