Dry vs. Wet Etching: Understanding the Difference and Their Uses
Dry vs. Wet Etching: Understanding the Difference and Their Uses In today's rapidly evolving technological landscape, the manufacturing of microelectronics, optoelectronics, and MEMS (Micro-Electro-Mechanical Systems) devices demands precision and accuracy. One of the key processes in the fabrication of these devices is etching, which involves selectively removing material from a substrate to create patterns or structures. Two main methods of etching are dry etching and wet etching, each with its own set of advantages and applications. In this article, we will explore the differences between dry and wet etching and their diverse uses in various industries. Dry Etching Dry…
