The AP5150 uses thermal CVD to deposit semiconducting, dielectric, and insulating films such as boron phosphor silicate glass (BPSG). Thermal CVD does not result in undesirable charging effects that can be present in films when deposited by a plasma enhanced CVD process.

Our proprietary planetary rotation design, shown in the video below, improves temperature, thickness, and composition uniformity. The planets are keyed with the main platen (sun) rotation and speeds are adjustable up to 10 rpm. The motion can be jogged by a foot switch for convenient loading and unloading of your wafers.

The lid houses a shower head for uniform injection of the precursor gases and vapors. The lid (with showerhead) tilts to face the operator for ease of access for cleaning and maintenance. The graphite sun and planets lift out for cleaning when required.

There are four (4) independent temperature zones with thermocouple control for adjusting radial temperature profile. Gas and vapor flow rates are controlled by mass flow controllers. All process parameters are recipe programmable.

The system is controlled by our proprietary CVDWinPrC™ software package. All digital sequences and analogue values are stored in the datalog files. The system is also controlled via the graphical user interface for troubleshooting and maintenance. The manual control panel has pushbutton controls for raising and lowering the lid, and alarm/warning reset. A programmable logic controller (PLC), housed in the system cabinet, runs continuously with safety interlocks.

The system is housed in an exhausted cabinet with gas leak detection. The reactor compartment is HEPA filtered to minimize the risk of particulate contamination of the wafers before and after deposition.

Bulkhead, through wall, and ballroom system placement options are available. The system shown here is bulkhead mounted with gas management system and electrical compartments accessible from your service chase.

powered by CVDWinPrC

Operated through our CVDWinPrC™ process control software, the systems automatically log data and graphically show time-dependent values of user-selected parameters. CVDWinPrC™ also allows users to load preprogrammed recipes, modify, check and create new recipes, and view realtime or saved process data.

Safety Protocols

The systems have application configured safety protocols embedded into relay logic, PLC, and CVDWinPrC™ software.
