Lapping/grinding, this is an operation where wafers where material removal is done with abrasive slurry. Chemical etching, after lapping or grinding wafer edges have residual damage this damage is removed. Wafer is cleaned from impurities coming from mechanical operations in the etching step. Donor ...
In silicon MEMS the silicon wafer provides both the substrate and the material for the active device layer. Additionally, polished silicon wafers are often bonded on the processed wafers to form hermetically enclosed packages. Mainly three types of wafers are used: polished bulk, epitaxial, and sil...
single crystal will behave as pure crystalline material, while a P-type wafer will have a higher concentration of holes than electrons. The wafer's orientation can influence its electronic properties and the depth of ions implanted in it. Ideally, the wafer should be sliced along a cleavage ...
Optically activated silicon microresonator transducers: An assessment of material properties 来自 Elsevier 喜欢 0 阅读量: 45 作者:D Walsh,B Culshaw 摘要: During the fabrication of silicon microresonators, boron is diffused into areas of the silicon wafer to define a beam structure. The subsequent ...
