Deposition Processes

INL cleanroom has three different physical vapor deposition (PVD) tools: UHV multitarget confocal sputtering tool from Kenosistec, a TIMARIS muti-target module and a TIMARIS flexible target module, both from Singulus Technologies.

The Kenosistec KS1000 PVD cluster tool with a confocal sputter-down configuration, optimized for wafers of up to 200mm in diameter. The system consists of a flexible UHV multi-target sputtering system with a deposition chamber with 11 magnetrons (∅2″) in confocal geometry for co-deposition of materials, and a oxidation chamber. It is especially designed for deposition of conductive and insulating films.

The Multi-Target Module (MTM) PVD cluster tool is especially designed for deposition of ultra-thin films, magnetic films, high-quality metallic, conductive and insulating films and multiple film stack deposition. The system is a UHV single-wafer cluster tool and consists of one transport module, one multi-target PVD module with 10 DC/RF cathodes and one soft etch/oxidation module.

The Flexible Target Module (FTM) PVD cluster tool is especially designed for deposition of high-quality metallic, conductive and insulating films. The system is a UHV single-wafer cluster tool and consists of one transport module, one multi-target PVD module with up to four DC/RF cathodes and one soft etch/oxidation module.

INL cleanroom has two different Chemical Vapour Deposition (CVD) tools: Plasma Enhanced CVD (PECVD) dedicated to silicon oxide and silicon nitride deposition and a CVD hot-wall tube furnace dedicated to graphene and carbon nanotubes growth.

The SPTS MPX CVD Module is dedicated to silicon oxide, silicon nitride and amorphous Silicon deposition by PECVD. It has a single-wafer processing chamber and dual high/low frequency RF options. It uses a plasma to enhance the chemical reaction rates of the precursors, which allows deposition of thin films at lower temperatures (typically <350°C) than in conventional CVD systems. The system is assisted by a multi-sided Transport Module, Vacuum Cassette Elevator(s) configured to accommodate substrates of 200mm. The vacuum cassette elevator can accommodate substrate cassettes with up to 25 substrates.

The CVD FIRST NANO EASY TUBE 3000 tool is a load-locked hot-wall quartz-tube furnace, which is commonly used for deposition of graphene and hexagonal boron nitride 2D materials. The system can operate in APCVD mode (atmospheric pressure) or LPCVD (low pressure vacuum) modes. It is a 3-zone furnace, with temperature control in a feedback loop that can be operated in Furnace or Cascade modes, for fast heating and precision temperature control, respectively. When in cascade mode, the system oscillates less than 0.2°C around the set point (up to 1100°C) for depositions lasting 1 hour or more. Except loading and unloading operations, all the other steps in a complete CVD process are controlled by programmable control software. The system can handle substrates up to 10×15cm.
