    Abstract: The present disclosure provides a method of fabricating a diamond membrane. The method comprises providing a substrate and a support structure. The substrate comprises a diamond material having a first surface and the substrate further comprises a sub-surface layer that is positioned below the first surface and has a crystallographic structure that is different to that of the diamond material. The sub-surface layer is positioned to divide the diamond material into first and second regions wherein the first region is positioned between the first surface and the sub-surface layer. The support structure also comprises a diamond material and is connected to, and covers a portion of, the first surface of the substrate. The method further comprises selectively removing the second region of the diamond material from the substrate by etching away at least a portion of the sub-surface layer of the substrate.

    Abstract: MEMS devices (40) using etched cavities (42) are desirably formed using multiple etching steps. Preliminary cavities (20) formed by locally anisotropic etching to nearly the final depth have irregular (46) sidewalls (44) and steep and/or inconsistent sidewall (44) to bottom (54) intersection angles (48). This leads to less than desired cavity diaphragm (26) burst strengths. Final cavities (42) with smooth sidewalls (50), smaller and consistent sidewall (50) to bottom (54) intersection angles (58), and having more than doubled cavity diaphragm (26) burst strengths are obtained by treating the preliminary cavities (20) with TMAH etchant, preferably relatively dilute TMAH etchant. In a preferred embodiment, a cleaning step is performed between the etching step and the TMAH treatment step to remove any anisotropic etching by-products present on the preliminary cavities' (20) initial sidewalls (44). The multi-step cavity etching procedure is especially useful for forming robust MEMS pressure sensors, but is applicable to any type of MEMS device.

    Abstract: A method of nanomachining is provided. The method includes plunging a nanometer-scaled tip into a surface of a substrate at a first location in a first direction that is substantially perpendicular to the surface, thereby displacing a first portion of the substrate with the tip. The method also includes withdrawing the tip from the substrate in a second direction that is substantially opposite to the first direction. The method further includes moving at least one of the tip and the substrate laterally relative to each other. In addition, the method also includes plunging the tip into the substrate at a second location in a third direction that is substantially parallel to the first direction, thereby displacing a second portion of the substrate with the tip and withdrawing the tip from the substrate in a fourth direction that is substantially opposite to the third direction.
