A cantilever-tip assembly for atomic force microscopy (AFM) or other scanning probe microscopy and its method of making based on micro-electromechanical systems (MEMS). Two crystalline silicon wafers and attached oxide and nitride layers are bonded together across an intermediate dielectric layer. A thin cantilever with a tetrahedral silicon probe tip at its distal end are formed in one wafer by anisotropic etching of silicon and a support structure is formed in the other wafer to support the proximal end of the cantilever preferably having an inclined face formed by anisotropic silicon etching. The cantilever may be silicon or silicon nitride.
