TFT Polysilicon - A4

CAC Name: TFT NP Poly

MRL Industries Furnace for polysilicon deposition on TFT compatible substrates

MRL Furnace
Manager: Phil Infante
Backup: Aaron Windsor , Daniel McCollister
Equipment Training
Training for the furnace area covers the pre-furnace MOS clean, atmospheric and LPCVD processes. It is scheduled on a need basis, please email the tool manager for training requests. Include MOS area training in the subject header. You will be notified when the next scheduled training will be by email.

Description:

The TFT N+/P+ Polysilicon Furnace is an atmospheric furnace with a 42” flat zone capable of processing up to 6” diameter wafers. Process gases available are SiH4, N2/PH3 and N2/B2H6 mixes for insitu doping, HCL for cleaning, and NH3 for silane based nitride films. Samples are restricted to silicon and TFT compatible glass materials only.

Capabilities:

  • Doped and undoped silicon films ranging from amorphous to poly
  • As-deposited doped film resistivities of 3-25 mohm-cm
  • Deposition temperatures from 450 to 670°C
  • Silane base silicon nitride films at 700°C
