SIMS Mass Spectrometer Details:
After a silicon wafer has been suitably augmented with dopants to display the requisite electrical resistance characteristics, it is treated through one of several different coating processes. Photolithography and photoetching are among the most common surface engineering methods used to develop nanoscale integrated circuits on semiconducting substrates by coating the surface with a light-sensitive material and applying a photoresistive mask to generate electronic patterns. Secondary ion mass spectrometry (SIMS) uses a miniscule bombardment of primary ions to analyse the uppermost layers of a substrate material. SIMS mass spectrometers are widely used to assess depth profiles of ion implants, as well as depth profiles of multi-layered stacks, MBE MOCVD (molecular beam epitaxy metal oxide carbon vapour deposition), or magnetron sputtered grown layers for example. SIMS depth profiling reveals the atoms/cc as a function of depth in an implant. For multilayer stacks, SIMS reveals the degree of diffusion between layers providing vital information on the growth process quality. A complimentary technique to SIMS is Temperature programmed desorption (TPD). The TPD Workstation measures desorbing species as a function of temperature from samples at UHV from ambient temperature up to a maximum 1000°C with rapid data acquisition of up to 500 data points per second. The TPD profile data reveal further details of the thin film growth process.
