All single crystal quartz should be growthed from one special seed. And the different cut type will cause the different seed location. One type is inside the wafer names "withseed", the other type is not inside the wafers, so names "seedless".

Orientation
1.AT & BT & SC etc such orientations are for many frequency control application which will be used for many electronic and space application, such as mobile phone and satellite etc;
2.Z cut is for some optical application, such as some windows and lens etc. meanwhile, general speaking, the polishing designations are for reducing the electronic resistence or enlarging the optical transmittance.

Seeded and Seedless Quartz
Single quartz crystal is growed from one special seed and then is divided into three zones, x/y & z zones.

Sedless means the wafers are in the pure x /y or z zone.
Our "standard" specs are:
* Flatness
Bow: 20um
Warp: 30um
* Roughness
Ra: 6 angstroms (on the polished side)

ST-cut means 42.75°Y -cut, x & y & z cut means 0°X or 0°Y or 0°Z-cut.

normally speaking, ST-cut type wafers are for surface acoustic waves application,
and other types are for some optical application.
