The electronics industry uses it in plasma and thermal cleaning applications for its advantages such as high etch rates, high selectivity, carbon-free etching, and minimal residual contamination.

由于它的优点，如高蚀刻率、高选择性、无碳蚀刻和最小限度的残留污染，电子工业把它用在等离子和热清洁应用中。

Moreover, the acid will further etch the fracture face and create deeper channels which leads to high fracture conductivity and better treatment effect even under high closure stress.

酸液在裂缝壁面上进一步刻蚀形成较深的沟槽，即使在高的闭合应力条件下，酸蚀裂缝也能保持较高的导流能力，从而改善酸压效果。

Once this is done, a series of chemical processes, some of which require high temperatures, are used to etch microscopic electrical circuits on to the chip's surface.
