The Alel "Speeder 100SiO 2" is an ICP Etching system which is configured for etch silicon using either the patented BOSCH Deep Silicon Etch Process or a Cryogenic etch process that are typically used in MEMS (Micro-ElectroMechanical Systems), microfluidics, and silicon masters for soft lithography stamps.The system is setup to process 4" wafers and uses etch masks
Plasma Etching techniques including RIE, PE, ICP, …
With a Planar ICP, etch profiles are typically anisotropic, and the very high Ion density makes this type of ICP source ideal for etching hard materials such as Quartz, and Silicon Carbide. The Planar ICP flat coil can cause issues with uniformity across the substrate, and various techniques have been used to reduce this effect such as moving the chuck height, and adding magnetics to shape the
Wet-Chemical Etching and Cleaning of Silicon
Table 2 relates silicon orientation-dependent etch rates of KOH to percent composition, temperature, and orientation. Table 2 is taken directly from . As with all wet-chemical etching solutions, the dissolution rate is a strong function of temperature.

charge build-up on the glass during DRIE. In the final step, silicon will be etched using DRIE. In this step there will be features with different widths on the mask. Unfortunately, they will have different silicon etch rates, narrower patterns having slower etch rates, due to a DRIE effect called microloading.
KOH Etching of Bulk Silicon - University of Alberta nanoFAB
using the disk style stir bar. The wafer was etched for a total of 60 minutes. The resulting etch depth was measured at several points across the wafer, as well as the thickness of SiN layer pre and post etch. Results: Etch Rate = 1.6um/min Selectivity = 49000:1 (using stoichiometric LPCVD SiN) Uniformity = 6.8% <100> <111> 54.7o
Silicon Carbide Etching Using Chlorine …
The etch rate, chemical reactions and etched surface of $\beta$-silicon carbide are studied in detail using chlorine trifluoride gas. The etch rate is greater than 10 μm min-1 at 723 K with a flow rate of 0.1 $\ell$ min-1 at atmospheric pressure in a horizontal reactor. The maximum etch rate at a substrate temperature of 773 K is 40 μm min-1 with a flow rate of 0.25 $\ell$ min-1.

25.01.2007· Figure 7 shows the average etch depth of the silicon features as a function of the XeF 2 etch time (each 2 minutes representing one etch cycle). An average of 13 µm of silicon are etched vertically per cycle, corresponding to an etch rate of ~6.5 µm min −1 , which is approximately 30 × higher than the etch rate measured in F 2 (0.22 µm min −1 ).

Investigating Different Methods of Bonding Glass Substrates
The wafer and glass substrate are placed between two metal electrodes and heated to 400ºC. By applying a DC potential up to 1kV, an electric field is created causing sodium ions to deplete the surface of the glass and to diffuse into the Silicon. In this state, the glass becomes highly reactive with silicon surface and forms a solid chemical bond.
