High Performance Metal Etchants for Semiconductor Packaging Applications


Metal etchants are used in semiconductor fabrication and packaging to chemically remove layers from the surface of a wafer during the manufacturing process. This hard mask removal is an essential part of device manufacturing, with each wafer undergoing multiple etching steps before completion.

Through its specialized TechniEtch product line, Technic offers a comprehensive range of etchants formulated for the diverse metals used in integrated circuits, optoelectronics, MEMS, and photovoltaic applications. Our products are designed to deliver controlled etch rates, uniformity, and excellent material compatibility across various process conditions.

As with all Technic products, we offer extensive experience and unparalleled customer service that have made Technic a trusted partner to leading semiconductor manufacturers worldwide.
