Abstract: A method of manufacturing a plurality of through-holes in a layer of first material, for example for the manufacturing of a probe comprising a tip containing a channel. To manufacture the through-holes in a batch process, a layer of first material is deposited on a wafer comprising a plurality of pits a second layer is provided on the layer of first material, and the second layer is provided with a plurality of holes at central locations of the pits; using the second layer as a shadow mask when depositing a third layer at an angle, covering a part of the first material with said third material at the central locations, and etching the exposed parts of the first layer using the third layer as a protective layer.

Abstract: A method of providing a MEMS device, such as an AFM probe, having a three-sided pyramidal protrusion is made using a multitude of MEMS method steps. To allow the reliable and speedy manufacture of such a MEMS device having a three-sided protrusion on a massive scale, wherein the protrusion has a relatively small half-cone angle and a single apex, a mold is used. The mold includes a sacrificial layer on top of a base substrate. The method of providing the MEMS device includes:



providing an area at the first side of the mold which area comprises a pit with a layer of protrusion material,
patterning the layer of protrusion material to the desired shape, and
isotropically etching the sacrificial layer of the mold with an isotropic etchant capable of etching the sacrificial layer so as to separate the MEMS device from at least the base substrate of the mold.
