Structuring of Si into Multiple Scales by Metal‐Assisted Chemical Etching

Advanced Materials, 2021
AbstractStructuring Si, ranging from nanoscale to macroscale feature dimensions, is essential for many applications. Metal‐assisted chemical etching (MaCE) has been developed as a simple, low‐cost, and scalable method to produce structures across widely different dimensions.

Vapor Phase Metal‐Assisted Chemical Etching of Silicon

Advanced Functional Materials, 2014
This work introduces and explores vapor phase metal‐assisted chemical etching (VP‐MaCE) of silicon as a method to bypass some of the challenges found in traditional liquid phase metal‐assisted chemical etching (LP‐MaCE). Average etch rates for Ag, Au, and Pd/Au catalysts are established at 31, 70, and 96 nm/min respectively, and the relationship ...

Metal Assisted Chemical Etch of Polycrystalline Silicon

Journal of Micro- and Nano-Manufacturing, 2022
Abstract Metal-assisted chemical etching (MacEtch) of silicon shows reliable vertical anisotropic wet etching only in single-crystal silicon, which limits its applications to a small number of devices. This work extends the capabilities of MacEtch to polysilicon which has potential to enable high-volume and cost-sensitive applications ...

Vertical etching with isolated catalysts in metal-assisted chemical etching of silicon

Nanoscale, 2012
Metal assisted chemical etching with interconnected catalyst structures has been used to create a wide array of organized nanostructures. However, when patterned catalysts are not interconnected, but are isolated instead, vertical etching to form controlled features is difficult.

Bulk Micromachining of Si by Metal‐assisted Chemical Etching

Small, 2014
Bulk micromachining of Si is demonstrated by the well‐known metal‐assisted chemical etching (MaCE). Si microstructures, having lateral dimension from 5 μm up to millimeters, are successfully sculpted deeply into Si substrate, as deep as >100 μm.

Metal-assisted chemical etching of molybdenum disulphide

2015 IEEE 15th International Conference on Nanotechnology (IEEE-NANO), 2015
Large-scale two-dimensional (2D) electronics requires lithographic patterning of molybdenum disulphide (MoS2) into various nanostructures for device integration. However, fabrication of MoS2 nanostructures with well-defined edges remains challenging.
