Etching Burried Oxide at the Bottom of High Aspect Ratio Structures

On this tool it is possible to run a switched etch process such as the BOSCH DRIE process as well as continuous etch processes such as dielectric etch or isotropic silicon etch,

The mechanical wafer consists of three layers, a 300 µm thick silicon substrate (yellow), a thin oxide layer (green) and a 35 µm thick silicon device layer (purple). The

Deep reactive ion etching (DRIE) is used to etch consecutively through the 40 µm silicon device layer, 2 µm buried oxide (BOX) and 300 µm silicon handle wafer.. In order to

Deep reactive ion etching (DRIE) is used to etch 7 x 70 µm trenches consecutively through the 40 µm silicon device layer, 2 µm buried oxide (BOX) and 300 µm silicon handle wafer.

successfully developed to etch a 2 µm BOX layer at the bottom of high aspect ratio trenches.  A simple and robust method for wafer-level encapsulation with non-photosensitive

There had been an innovative report prepared by Lord Dawson in 1920 for the Minister of Health’s Consultative Council on Medical and Allied Services, in which he used his

As part of enhancing the EU’s role in both civilian and military crisis management operations, the EU therefore elaborated on the CMCO concept as an internal measure for

Measurements of transmission and refraction in the marine boundary layer have been performed during the September 2011 SQUIRREL trial, and have been compared with results from
