In Situ Observation of an Electrochemical Etching Reaction in Silicon

  • Frances M. Ross (a1) and Peter C. Searson (a2)
Abstract

We describe a TEM specimen holder which has been designed and constructed in order to observe the process of electrochemical pore formation in silicon. The holder incorporates electrical feedthroughs and a sealed reservoir for the electrolyte and it accepts lithographically patterned silicon specimens. We present ex situ observations of progressive pore propagation and show dynamic, in situ observations of electrolyte movement within the pores.
