Scope of application: This standard applies to the inspection of all blanks and some process inspections; During outgoing inspection, selection should be made according to process requirements, and process inspections should be carried out according to Level I standards.
In the semiconductor industry, we often mention wafers, such as fused quartz wafers, fused silica wafers. Let's take a look at the foundations of the semiconductor industry-Wafers!
the relationship of SAW substrates between orientation and flat
Lithium Niobate Thin Films on Insulator is kind of POI (Piezoelectric on Insulator) wafer. It's stacked sequence structure is made of support substrates that can be silicon, quartz, fused silica, sapphire or LN wafer, the interlayer is thermal oxide SiO2 that works as insulator and lithium niobate film is the functional layer above the insulation
