LU-4000 Series

POCl3 Auto Refill System FDM Series

POCl3 Auto Refill System

HORIBA's Award Winning Fluid Delivery System (LU-4000 Series) has revolutionised the POCl3 diffusion process by developing a system to automatically deliver bulk liquid POCl3 in 20 litre ETFE lined stainless steel canisters to multiple fixed plastic bubbler vessels.

The LU-4000 series and VM series are used for n-type diffusion layers as a dopant in manufacturing crystal silicon-based solar cell.
The system can also be used in the BBr3 diffusion process, improving process stability, increasing uptime, reducing logistics and labour costs and higher safety.

  1. Higher productivity
    The VM Series (Vapor Delivery Module) achieves higher productivity due to minimizing downtime as it does not require a traditional quartz bubbler exchange
  2. Reduced running costs
    The LU-4000 Series reduces consumption of POCl3: up to 30% lower price per kg
    More than 99.8% uptime due to continuous production
    Decrease the cost of POCl3 waste
    Longer tool lifetime and lower maintenance costs due to the process line never being exposed to the atmosphere
    Delivered by 20L canister reduces logistics, storage and handling costs
    Fewer POCl3 exchanges and bottle returns result in lower labor costs
  3. Improved process stability
    The VM Series keeps the liquid level ”High” resulting in the pick-up rate being more stable than a traditional quartz bubbler
    There is no affect by liquid level due to the bubbler being continually refilled
    No bubbler exchanges are needed resulting in no exchange mistakes
    There is no affect from ambient temperature fluctuactions
    Sheet resistance is more stable than traditional bubblers resulting in improved sheet resistance repeatability and reproducibility.
  4. Improved safety
    No more quartz. The VM Series is made from PFA vessel which is much more robust than quartz, no handling, exchanges or refilling of quartz bubblers are needed as it does not require periodical exchanges resulting in less opportunities for human error.
    POCl3 is delivered in 20L ETFE lined stainless steel containers and contained in fixed and robust PFA vessel.
    Robust, leak tight bubbler housing with N2 blanket and connected to facility exhaust
    Integrated liquid leak and gas leak detection
    Wetted lines fully purged and leak checked automatically.
  5. Improved reliability
    POCl3 is hydrophilic and produces phosphoric acid which can cause corrosion or crystallization. A normal bubbler requires periodical exchanges and when a bubbler is exchanged the possibility of contact with air increases. The HORIBA POCl3 Auto Refill System does not require exchanges of the bubbler resulting in a very low chance that POCl3 tubing makes contacts with the air.
