STE MS900 Versatile Magnetron and Resistance Sputtering System for Batch Wafer Processing

New versatile System for magnetron and thermo resistance sputtering for batch wafer processing

STE MS900 System allows to sputter multicomponent layers (metals, resistant layers, ITO layers etc.) on thesubstrate heated up to 700°C. System is designed for both active R&D and small-scale production. Maximumnumber of sputtering substrates in the same process: ∅150 mm – 5 pcs. Targets with diameter of 8’’ ensureuniformity of ±2% for ∅100 mm. Magnetic mount makes targets replacement very easy.Optimized high vacuum stainless steel reactor, consisting of a stationary source unit and lifting the top cover.Updated ergonomic design of the reactor is equipped with lifting mechanism for convenient routine maintenancewith evaporator unit.

• water-cooled HV stainless steel reactor with lifting top flange
• 5 ports for material sources with targets up to ∅8’’ (∅200 mm) and 1 port for ion source
• carousel type substrate holder with the possibility of varying the samples sizes
• 2 magnetron sources with target diameter up to ∅200 mm and individual valves, 2 power sources (DC andRF) with automatic reconnection between the magnetrons in basic configuration and ability of setting optionalmagnetrons for Customers’ inquiry
• ion source (ions energy 20÷300 eV) for substrate cleaning prior the deposition with the protective screenssystem
• 3 gas lines with automatic gas flow controllers including a corrosion-proof performance bypass line
• process gases: Ar, H2, O2, N2
• ability to install the witness-sample for resistance measuring
• substrate positioning relative to the specified sputtering source
• up to 5 quartz thickness monitors (with a quartz resonator for each magnetron sputtering sources position)located in the line of sight of each source
• alternating bias to the sample is available
• automated process control system with automatic lock installation on the energy resources (air, water, puregases)settings and the target system parameters
• operating modes: automatic, semi-automatic, manual

• using as multifunctional System for vacuum deposition with different sources for R&D and small-scaleproduction
• optimized System ergonomics allows for convenient operation and maintenance
• sputtering geometry (from bottom to up) allows to minimize the defects density on the sample surface
• automated process control:
– thickness gauges indications, sample resistance measuring, etc.
– with automatic lock setting based on the energy resources (air, water, pure gases)
