Latest Patents

Dawn's latest patents focus on an etchant formulation for selectively removing thin films in the presence of copper, tin, and lead. This invention relates to a ball-limiting metallurgy (BLM) etching system and process. The BLM stack is designed for an electrical device that includes an aluminum layer on a metal first layer. Additionally, a metal upper layer is positioned above a metal second layer, with an alternative metal third layer situated between the second and upper layers. The etching system utilizes a solution that comprises a nitrogen-containing heterocyclic compound, an ammonium hydroxide compound, an oxidizer, and a metal halide compound. The etching conditions are carefully controlled to prevent any dissolved metallization from redepositing, thereby avoiding lowered yields.
