Dear Mr Choi,

Good Evening

Thank you for your kind email and attached are pictures taken last week the USA facility:

Picture 1: coin-rolled wafers 

Picture 2:  300 mm Sandblasted wafers using aluminum oxide.  

Picture 3:  300 mm wafers in FOSBs

Picture 4:  Variuus source wafers

Picture 5 & 6:  Broken wafers packed in Gaylord boxes, about 800 kgs per box

We have a constant flow of source material arriving and interested in developing 1 or 2 new customers especially in solar and or semiconductor industry.

Will check the qty, price and offer to you ASAP

Please let me know if you have any questions.

with best regards,

We have several grades of silicon in hand at this time:

1.  Metalurgical grade wafer:  broken silicon wafers in barrels.

2.  Solar Grade wafers:  200 mm and 300 mm wafers that have been sandblasted to remove surface materials

**Need one last sorting step and a quick clean to remove any aluminum dust

3.  Semi grade wafers reclaim rejects:  150 mm, 200 mm, and 300 mm 

• Various films
• Packed in cassettes or FOBSs or coinroll

4.  Semi grade wafers standard thickness:  150 mm, 200 mm, and 300 mm 

• Various films
• Packed in cassettes or FOBSs

Perhaps we can start a dialogue about these materials?

Looking forward to hearing from you
