The present disclosure relates to a MEMS package having different trench depths, and a method of fabricating the MEMS package. In some embodiments, a cap substrate is bonded to a device substrate. The cap substrate comprises a cap substrate bonded to a device substrate. The cap substrate comprises a MEMS trench, a scribe trench, and an edge trench respectively recessed from at a front-side surface of the cap substrate. A stopper is disposed within the MEMS trench and raised from a bottom surface of the MEMS trench.
