1. It is an anisotropic etchant of silicon, exposing octahedral planes. 2. It finds increasing use as an etchant in microelectronics. 3. To overcome this problem an anisotropic etchant is used. 4. The resist protects the non-image areas of the cylinder from the etchant . 5. The first is over etching, which means the etchant was applied too long. 6. The long shelf life of this etchant allows the solution to be stored in large quantities. 7. Trimethylsilane is used in the semi-conductor industry as an etchant in the plasma phase. 8. This etchant is used by metallographers to provide contrast between binder and carbide phases in cemented carbides. 9. The resulting brown, acidic, and etchant for copper-based metals in printed circuit boards. 10. The second is due to an isotropic etchant , which means the etchant etches in all directions equally.
