What we do

Two roles, one source

Import & Distribution

A stocking distributor of electronic materials.

We import and stock semiconductor and electronic materials, partnering with manufacturers for EPI layer deposition, thin-film processing, and wafer dicing, frequently supplying materials unavailable elsewhere in the US market.

  • Monocrystalline silicon ingots & wafers
  • Compound semiconductors & EPI structures
  • EPI deposition, thin-film processing & dicing partners
Specialty Manufacturing

A manufacturer of ultra-precision silicon wafers.

We produce wafers of ultra-high precision, extremely high purity, and uncommon crystallographic orientations, built to specifications most suppliers can't or won't take on.

  • Thickness from 40µm to 10,000µm
  • Double-side-polished, TTV < 1µm
  • Specialty orientations: (110) and (211)
