LINEA – Inline Wet Process Equipment
for Cleaning, Texturing and PSG removal


Today´s dominating solar cell concept is based on cells made from crystalline silicon. STANGL provides complete automated dry-in/dry-out solutions for wet treatment of Si-wafers in standard and high-efficiency cell lines.

While batch-type working wet benches (SILEX series) are the first choice for cleaning and alkaline texturing of monocrystalline wafers, the manufacturing lines of multicrystalline solar cells preferably apply acidic texture processes on inline-working machines. PSG removal processes are running successfully in batch and inline-type equipment, following more or less the philosophy of the whole manufacturing process.

Additionally, inline equipment permits singleside etching, applicable for edge isolation or sideselective surface treatment. LINEA is a horizontally working inline wet process platform for cleaning and etching of crystalline solar wafers.

LINEA inline etching system can be configured up to max. 1,700 or 3,400 wafers per hour (156 mm) which equals a production capacity of 50 and 100 MW. LINEA completes the portfolio of STANGL’s integrated wet process
solutions for solar cell manufacturing lines.




The LINEA design is based on a newly developed
sophisticated transport system and a special
chemical flow system to process the wafers
horizontally with a very low breakage rate and a
high etching uniformity. STANGL’s new system
LINEA follows the trend towards handling solar
wafers down to 150 μm.

The highly integrated design, high throughput, high
availability and low breakage rate make LINEA
attractive for solar cell manufacturers worldwide.
