Wafer Reclaim and Recycling WAFER RECLAIMING  Silicon Wafer Recycling Wafer Reclaim is reconditioning the surface of a processed wafer. Films are chemically removed and the surface is polished so the wafer can be cleaned to the LPD specification required. Crystal defects in the wafer will not be altered.Wafers can be reclaimed to suit your needs. Whether you need ultra clean reclaim wafers or a basic handling wafer without an LPD requirement, OneSourceMetals can provide wafers that meet your exact specification. Once we build up an inventory of your wafers that have been reclaimed to your specifications, the wafers can be stored at One Source Metals and you can request shipment as needed to save space and make sure you are paying for wafers only when you actually need them. We now offer Silicon recycling services for a Cleaner, Greener Earth.All of the Silicon material that we purchase will be remelted and used for the manufacturing of solar cells and panels.We are looking to purchase and recycle all types of Silicon Products in all forms including(but not limited to); Broken Wafer Patterned or bare Whole Wafer Patterned or bare Silicon Poly Chunk Pot Scrap IC Grade Tops & Tails IC Grade Ingot The Silicon material we are using for Remelt Solar Applications should be in the resistivity range of; 0.5 ohm per cm. and above for P-type 1.0 ohm per cm. and above for N-type We are able to pay very competitive prices for materials with the above specifications. We can also purchase Silicon materials under these specifications. Contact us for more information. ONE SOURCE METALS CAN HELP YOU SAVE Chip manufacturers burn through thousands of test wafers in developing production processes and bringing a new fab line on line. With 300mm wafers costing as much as $300 each, the need to recycle those test wafers is increasing. Recycling test wafers has proven to save a typical chip company $4m to $6m a year in 200mm wafers alone. Those savings could increase to tens of millions of dollars in each 300mm fab. The problems is that most test wafers today include copper films which are difficult to remove without also shaving off a few microns from the actual silicon wafer substrate. This is because copper molecules, not properly sealed, tend to migrate into the silicon substrate. |
