I am having difficulty locating a source of FZ wafers with the following spec. * Orientation: <100> * Resistivity: >1000 Ohm cm * Thickness: 525 microns (or thicker) * Dia. 100mm preferable * Quantity: Initially I need just 12 wafers but will purchase a larger batch if necessary. Can anybody supply these or offer any advice on where to obtain them? -- Tony Rogers Applied Microengineering Ltd (AML) 68 Milton Park, Abingdon, OXON, OX14 4RX, UK Tel: +44 (0) 1235 833 934 Fax: +44 (0) 1235 833 935 WWW: http://www.aml.co.uk
