As a member of IQE plc, Wafer Technology’s characterisation portfolio also extends to the regular use of an extensive Group metrology service which is comprised of many state-of-the-art wafer assessment tools. These include advanced surface analysis by atomic force microscopy (Veeco Digital Instruments DI3100) and 3D surface profilometry (Taylor Hobson Talysurf CCI 3000). Electrical assessments are made using contactless sheet resistance (Lehighton LEI 1500RS) and layer thickness determinations by infra-red microscopy (Film Expert MKS 2140). Metrology is a critical aspect of product conformity and together with our own in-house range of assessment tools enables us to deliver the highest quality of product.
