We are looking for buyers for silicon ingot scrap for semiconductor applications. Product Overview Product types: Top & Tail, side pieces, ingot scraps, etc.
Ingot size: 12 inch and 8 inch are the mainstream, 6 inch is a little
Stock amount: Over 100 tons
Product raw material: Ingot for semiconductor use (11N product)
Mainly CZ products, small amount of FZ products
Product characteristics
Doped: Basically phosphorus and boron
N type & P type (both available)
Resistance value: 1 or more, 5 or more (separate storage)
Carbon content: As it is 11N product, the carbon content is in PPM units.
All products are inspected (N type/P type, resistance value, visual inspection)
Sales method: Approximately 25 tons delivered by container
MOQ: 25 tons/month, 1 year continuous contract
(Spot trading is also possible, but the unit price will change.)
Payment method: 100% advance payment Delivery method: EXW or delivery to a designated port (additional cost required)
Unit price: 7USD/kg
Submission of quality inspection certificate: Inspection certificate as evidence of the shipped product
Documents to be submitted: Shipping judgment slip (X-ray fluorescence analysis data attached) / for each shipment Judgment items:Â Visual check ... No foreign matter, oil, or moisture (excluding identification stickers, fixing tapes, crystal orientation markings, etc.)
Weight check ... Matches the slip (within +3kg/-0% per package)
Component analysis ... No detection of P (phosphorus) (N.D.)
Analysis method: Randomly sample samples from each shipping lot and perform qualitative analysis using X-ray fluorescence. Quantitative analysis is performed on lots that detect P (phosphorus) spectrum during sampling inspection.
Basically, it can be exported to the whole world except for some regions.
This product is a semiconductor-level crystal, so it is a product for 100% remelting. When purchasing, you must agree to the pledge.
