Our company ordered a Gold sputter target of 99.5% purity, 2.0" diameter and 0.250" thickness for our semiconductor production. The product was delivered promptly and was well-packaged. The gold target performed excellently in our SEM coating process, and we noticed a significant increase in the signal-to-noise ratio. Highly recommended!
Used these for classroom chemical projects and experiments. Works great.
Due to the high quality of the gold sputtering materials, the film I obtained is of extremely good uniformity! Love it! Thank you！
Satisfying customers with high-quality products is always SAM's service tenet. We are very happy that our products are helpful for your project. Thank you for your trust.
FYI: Keep the target clean before coating, so as to maintain the uniformity of the film.
I bought the gold sputtering targets for jewelry coating. The good thing is that SAM offers different purities of the gold sputter target, so that you can purchase on your own budget. I bought a 99.999% purity au target, and the obtained gold film has a good gloss and uniformity. five stars.
