Silicon Valley Microelectronics provides a wide variety of lithography and other wafer patterning solutions to the semiconductor and MEMS industries. Standard test patterns are available for CMP, etch, clean, and medical device manufacturing markets on glass and silicon substrates.
In this paper, a novel trench etching technique for silicon carbide is described. In this technique, ion implantation is used to first create an amorphous silicon carbide region. The amorphous layer is then etched away by wet chemical etching. Trenches of 0.3 to 0.8 μ have been obtained using a single implantaion/etching step. It has been demonstrated that deeper trenches can be obtained by
Clas-SiC is unique in offering circa 4 week cycle times for Diode level SiC wafer processing to accelerate R & D and time to market for new device designs. Mosfets & Switches are targeted at 8 weeks for R & D lots. Clas-SiC has invested in medium scale SiC
popular anisotropic wet chemical etching in terms of the etch profile and most especially the etch rates. The understanding of this concept is useful for future appliions in the fabriion of ultra thin IBC solar cells. 2. EXPERIMENT Crystalline Silicon wafer (4 2
In this paper, a review of the current understanding and practice of reactive ion etch-ing of SiC is presented. We concentrate on the fluorine-based RIE of 6H-SiC, the most widely used polytype. However, some results in the plasma-assisted etching of 3C and 4H
structures and to etch for a longer time. In our case, undoped LPCVD polycrystalline silicon is used as an etching mask because it is not attacked by an HF solution. Before the LPCVD process, the silicon carbide wafers are thermally ox-idized to grow a thin2
Wet etch processes are generally isotropic in nature, which is often indispensable for microelectromechanical systems, where suspended structures must be “released” from the underlying layer. The development of low-defectivity anisotropic dry-etch process has enabled the ever-smaller features defined photolithographically in the resist to be transferred to the substrate material.
Silicon Carbide Abrasive TP Tools & Equipment Silicon Carbide is the highest-quality abrasive in our line stays sharper and lasts longer than any other abrasive. This abrasive is the favorite for glass etching and heavy automotive parts cleaning due to its high quality and ability to be recycled over and over again.

Wet chemical processes are typically isotropic, i.e., they etch in all directions with the same rate. However, both dry and wet etching can be anisotropic by causing an etch rate variation with different material crystal orientations . 1.2.3 Deposition
