Silicon substrate:  Bulk Czochralski, bulk floatzone or SOI

Substrate Dopant:  FZ: Boron or Phosphorus
Cz: Boron, Phosphorus, Arsenic or Antimony

Epi Layer Dopant:  Boron, Phosphorus or Arsenic

Number of Epi Layers: 1, 2 or 3

Epi Layer Resistivity Available Range:
     p-type: .009 to 1000 ohm-cm (thickness dependent)
     n-type: .005 to 2000 ohm-cm (thickness dependent)

Epi Layer Thickness Available Range:  0.5 to 500 m

Epi for a Variety of Devices:   Aeroflex / Metelics is an experienced manufacturer of epi
wafers tailored for the following discrete silicon devices:

  • PIN diodes (RF and photodiode)
  • Varactor diodes
  • Schottky diodes
  • Bipolar transistors
  • MOSFETs
  • JFETs
  • IGBTs
  • MEMs

Quality Assurance:  Aeroflex / Metelics is an ISO 9001 facility. Epi wafers are inspected per the relevant SEMI standards. Our in-house epi measurement equipment includes:

  • FTIR for measurement of epi layer thickness;
  • C-V Hg-probe for measurement of epi resistivity;
  • Spreading resistance profile (SRP) for measurement of epi resistivity vs depth;
  • Four point probe for measurement of epi resistivity atop a p-n junction;
  • 100% visual inspection using a high intensity Yamada inspection lamp.

Capacity:  Aeroflex / Metelics can grow small quantity, one-time orders as well as high volume blanket orders. We can rapidly add production shifts in order to fulfill surge demand for epi wafers.

Experience:  Aeroflex / Metelics silicon epi group is comprised of highly skilled and experienced technical staff, some with over 25 years of experience in the silicon epi industry. Like the rest  of Aeroflex / Metelics, we are highly customer focused. We conduct production / planning meetings daily in order to promote on time delivery.
