18″ Silicon Wafers
Silicon Valley Microelectronics does not carry stock of 450mm wafers. 450mm silicon wafers are the newest and largest size wafers available on the market, capable of making 5 times more chips than the more standard 200mm wafers. If you require these wafers, SVM can custom manufacture them to your specifications, or use one of our manufacturing partners to procure smaller quantities. Please contact an SVM sales representative for more information on these wafers.
