Claim:
1. A method of manufacturing a microelectromechanical system (MEMS) device, the method comprising: forming a monocrystalline sacrificial layer on a non-silicon-on-insulator (non-SOI) substrate; patterning the monocrystalline sacrificial layer such that the monocrystalline sacrificial layer remains in a first portion and is removed in a second portion lateral to the first portion; depositing a first silicon layer, the first silicon layer deposited on the remaining monocrystalline sacrificial layer and further lateral to the first portion; removing at least a portion of the monocrystalline sacrificial layer via at least one release aperture in the first silicon layer to form a cavity; and sealing the cavity.
