Effects of deep reactive ion etching parameters on etching rate and surface morphology in extremely deep silicon etch process with high aspect ratio

open access: yesAdvances in Mechanical Engineering, 2017
This study empirically investigates the influences of several parameters on surface morphology and etch rate in a high-aspect-ratio silicon etching process. Two function formulas were obtained, revealing the relationship between the controlled parameters

Silicon Deep Reactive Ion Etching with aluminum hard mask

open access: yesMaterials Research Express, 2019
Silicon Deep Reactive Ion Etching (DRIE) process using a multi-layer mask containing a sputtered Aluminum thin film is studied. Aluminum is a candidate for very high aspect ratio DRIE, due to tis very low etch rate, but its adoption is hindered by the presence of micromasking.

Deep reactive ion etching of auxetic structures: present capabilities and challenges [PDF]

open access: yes, 2014
Auxetic materials (or metamaterials) have negative Poisson ratios (NPR) and display the unexpected properties of lateral expansion when stretched, and equal and opposing densification when compressed. Such auxetic materials are being used more frequently

Three step deep reactive ion etch for high density trench etching

open access: yesJournal of Physics: Conference Series, 2016
A three step Deep Reactive Ion Etch (DRIE) process is developed to etch trenches of 10μm wide to a depth of 130μm into silicon with an etch rate of 2.5μm min-1. The aim of this process is to obtain sidewalls with an angle close to 90°. The process allows the etching of multiple trenches with high aspect ratios that are closely placed together.

Low-temperature smoothing method of scalloped DRIE trench by post-dry etching process based on SF6 plasma

open access: yesMicro and Nano Systems Letters, 2020
Deep reactive-ion etching (DRIE) is commonly used for high aspect ratio silicon micromachining. However, scalloping, which is the result of the alternating Bosch process of DRIE, can cause many problems in the subsequent process and degrade device ...
