Title: Mass sensor for in situ monitoring of focused ion and electron beam induced processes

Abstract

A cantilever-based mass sensor for in situ monitoring of deposition and milling using focused ion and electron beams is presented. Carefully designed experiments allowed for mass measurements with a noise level of {+-}10 fg by tracking the resonance frequency of a temperature stabilized piezoresistive cantilever using phase locking. The authors report on measurements of precursor surface coverage, residence time, mass deposition rates, yields, and deposit density using the (CH{sub 3}){sub 3}PtCpCH{sub 3} precursor.
