• 12:3212:32, 8 September 2025 diff hist +3,281 N Ga removal from backside of GaAs wafers Created page with "When receiving GaAs wafers, they often come with a layer of gallium on the backside. This layer has turned out to cause quite some troubles, as it introduces an uneven surface on the backside of the wafers. The rough gallium on the backside tends to give high sample inclination and makes it difficult to handle small samples. You can request the growers to remove this Ga layer before shipping. Meanwhile, you need to remove the Ga from the wafers. =Techniques from John W..." current
