  • Publication number: 20250236514
    Abstract: In a micro-electromechanical system (MEMS) structure, at least one chemical stop structure is formed to reduce inadvertent etching of adhesion layers. A first adhesion layer and a second adhesion layer are separated by a primary dielectric layer. The primary dielectric layer includes a recess that forms a stair. The second adhesion layer includes an annular opening, and a protective material covers the sides of the second adhesion layer in the annular opening. A base plate layer covers the second adhesion layer and fills the recess and the annular opening. An annular via passes through the base plate layer and the protective material down to the primary dielectric layer. The protective material and the base plate layer each act as chemical stop structures that separate the first adhesion layer from the second adhesion layer.
