WebThis paper demonstrates how a low undercut Ti etchant developed by Technic France can be successfully introduced in a high volume manufacturing Fab for etching the under bump metallization (UBM). The Ti etchant has been tested on 300mm wafer production equipment in GLOBALFOUNDRIES. WebThe etching of Ti and TiN is shown to be fundamentally different from the etching of SiO 2. The mixture of Ammonium-hydroxide and Hydrogen Peroxide must be optimized differently for Ti and TiN etching than for the particle removal from Silicon wafers.
