FAQ about MCZ Silicon Wafers
Q：This is just a curiosity, but let me ask about the production method of your MCZ ingots.
I think there are 3 methods for MCZ growth, but which one(s) does your factory adopt?
1. Longitudinal Magnetic Field Method (A magnetic field created by an electromagnet is applied perpendicularly to the melted silicon surface.)
2. Transverse Magnetic Field Method (A magnetic field created by an electromagnet is applied parallel to the melted silicon surface.)
3. Cusp Magnetic Field Method (A pair of electromagnets are placed on top and bottom to create magnetic fields in opposite directions.)
And, I am asking this also just for a curiosity because our customer requires MCZ silicon ingots, but could it also possible to meet all the required specs simply with CZ?
Or does it have to be MCZ to meet the specs?
A：We grow MCZ monocrystalline silicon ingots with Transverse Magnetic Field Method.
Magnetic Field will improve the resistivity uniformity (RRV), some customers specify MCZ if they’re strict on RRV.
Other parameters are not different with CZ
