  2. The block is less than 30mm

  3. There should be no oxide interlayers and infusible materials, and it is best to use wash-free materials.

  E. Zone melting head and tail material

  skills requirement

  1.N type, resistivity is greater than 50chmom and minority carrier lifetime is greater than 100μm

  2. The block is larger than 30mm

  3. There should be no bubbles in the zone melting head and tail materials, no contamination caused by contact with the coil, and no flowing silicon or infusible matter from the zone melting process.

  4. Preferably no-wash material

  F. Straight-pull head and tail materials (IC materials), preferably no-wash materials

  1.N type, resistivity is greater than 10ohmom

  2.p type, resistivity greater than 0.5ohmom

  3. The block is larger than 30mm and the thickness is larger than 0.5mm.

  4. There should be no air bubbles or infusible matter in the straight-pull head and tail materials.
