Sandblasting (or, more precisely, abrasive blasting) is a widespread method for cleaning and roughening surfaces. The main purpose of our Microblaster is roughening the backsides of Si wafers for infrared ellipsometry. However, it can be used in many activities including making frosted glass, marking hard substrates, cleaning and deburring delicate parts, etc.
