Latest Patents

Huang's latest patents include an etchant formulation for selectively removing thin films in the presence of copper, tin, and lead. This invention relates to a BLM etching system and process designed for electrical devices. The BLM stack consists of an aluminum layer on a metal first layer, with a metal upper layer above a metal second layer, and an alternative metal third layer situated between the second and upper layers. The etching system utilizes a solution that contains 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.
