Silicon Chips

Square chips of silicon are ideal substrates for Microscopy and Spectroscopy applications.   The chips are 10-mm square and 525-µm thick.  See bottom of page for additional properties.

 

Silicon Chips

Square chips of silicon are convenient and ready to use.  Polished silicon exhibits  low roughness.  Atomically flat surface enables high resolution imaging for AFM and SEM applications.

Silicon Chips Coated with Metals or Silica

Chips coated with gold (Au), platinum (Pt), or silica (SiO2).  The metals are 99.999% pure.  Physical vapor deposition (e-beam evaporation) enables high quality metal films.  Silica film deposited via wet oxide process.

Don’t see what you need?  We can coat most metals (Ag, Ni, Ti, etc.) on to silicon.  Also, we can cut wafers and chips to any size (>5 mm).
