Webetch-stop layer was imbedded between the polySi and the Si, which produced a relatively flat bottom profile after the etching process (Fig. 1E). The tip area could be further increased by using addi-tional etching techniques such as an overetching of the polySi (Fig. 1F) and a wet etching of the etch-stop layer (Fig. 1G).

WebThe slanted etching process may include one or more sub-steps. The slanted etching may be performed by, for example, rotating structure 900 and etching the layer of grating material 920 by the etching beam based on the desired slant angle. After the etching, a slanted grating 950 may be formed in the layer of grating material 920.
