Abstract: Wafer-level quartz dry etching technology has been developed, which enables deep reactive ion etching (DRIE) for through-etch of ≥120-μm-thick crystal quartz wafers and an X-cut quartz DRIE. Our DRIE process employs direct wafer bonding of crystal quartz and silicon wafer by means of surface active bonding at room …
Quartz is one of the most common minerals in the Earth's crust. As a mineral name, quartz refers to a specific chemical compound (silicon dioxide, or silica, SiO 2 ), having a specific crystalline form (hexagonal). It is found is all forms of rock: igneous, metamorphic and sedimentary. Quartz is physically and chemically resistant to weathering.
Stainless Steel Wafer Cassettes. YES cassettes are designed to achieve accurate wafer support with minimal mass. Temperatures remain uniform throughout heat up and cool down applications minimizing hot/cold spots due to heat sinking. Cassettes are placed with the wafers vertically in YES-450PB Series ovens to facilitate the laminar flow process.
