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.
TechniEtch TBR19
TechniEtch TBR19 is an enabling, fluoride-free aqueous solution, designed to selectively dissolve titanium (Ti) and titanium alloy-based (TiN, TiW) barriers for far back-end of the line (BEOL) interconnect applications. This high-performing metal etchant can significantly reduce undercut. Techni Etch TBR19 is compatible with most UBM and copper pillar integration materials such as Cu, Al, Ni, Sn, and alloys, glass, organic substrate, etc.
TechniEtch CN10
TechniEtch CN10 is an acidic-based copper metal etchant, containing particular additives that greatly enhance stability and metal loading capability in RDL (Redistribution Layer) applications, as compared to conventional oxidative acidic-based solutions. Highly tunable at point of use with great selectivity for UBM Cu and Ni etching.
TechniEtch ACI2
An iodine-based gold metal etchant that contains highly effective proprietary additives that greatly enhance the stability and metal loading of the solution compared to standard iodine-based etchants. The main attribute of the solution is that the gold etching rate is not impacted by bath loading, aging, and cross-contamination level.
Other TechniEtch Products
TechniEtch Cr01 is a standard cerium ammonium nitrate based chemistry formulated to address selective chromium etch.
