SEM secondary ion optics and photomultiplier detector for Applied Materials
HPD worked from a customer-supplied concept to engineer the electron optics and their mountings coupled with a
photomultiplier tube (PMT) detector to form a field-replaceable unit for scanning electron microscopes (SEM). HPD built
the initial prototype and then a small pre-production batch of assemblies including shippable vacuum containers to house
the assemblies. HPD also developed assembly and test procedures and documentation.
