Description

The Plasma-Enhanced Chemical Vapor Deposition (PECVD) system is an Oxford Instruments Plasma Technology PlasmaPro System 100 platform that is optimized for silicon dioxide and silicon nitride deposition. The PECVD has a variable temperature stage (RT to 600 °C). This system supports wafer sizes up to 6 inches, and provides PECVD film growth over a wide range of process conditions.

Applications
  • Silicon Dioxide Deposition
  • Silicon Nitride Deposition
Allowed material in PECVD System
  • Si, SixNy, SiO2, SOI
  • Hard masks compatible with process temperature
  • Other materials buried in stack
PECVD Gas List
  • 5% SiH4 in N2
  • 5% SiH4 in Ar
  • NH3
  • N2O
  • N2
  • O2
  • CF4 (for plasma clean)

System Features
  • Process module frame and separate control rack that house the electronic sub systems, control units, pneumatics, and turbomolecular pump
  • PTIQ operating system
  • PECVD process chamber with 160 mm pumping port, view port, and an additional rear port for optical emission end-point-detection
  • Heated upper electrode to prevent condensation of low vapor pressure precursors
  • PECVD 205 mm electrically heated (700 °C) lower electrode with central wafer lift mechanism
  • Parameter ramping software
  • 5 Torr capacitance manometer for process control, and penning for base pressure measurement
  • Process chamber pumping with 63 mm branch to APC, and isolation valve; chamber base pressure turbo, backed by a refurbished dry pump with roots
  • Twelve line gas pod with two non-toxic and three toxic digital mass-flow-controlled gas lines and cleaning gas
  • Chamber Gas ring, with split gas manifold
  • Liquid vapor delivery system
  • Single-wafer automatic insertion load lock with soft pump option
System Specifications
  • Chamber wall heating 80 °C
  • 30/300 W RF generator close-coupled to the upper electrode through an automatic matching unit; the generator is configured to operate in a low-power mode (0-30 W) for higher accuracy during low-rate deposition processes
  • 600 W solid-state 50-460 kHz LF generator
