Why Single Crystal Silicon Demands Precision Machining
As the backbone of modern electronics, single-crystal silicon powers devices from smartphones to supercomputers through its:
◼ Highly ordered crystal structure
◼ Superior electrical properties (high carrier mobility >1,500 cm²/V·s)
◼ Critical role in semiconductor manufacturing (ICs, transistors, diodes)
In photovoltaic systems, monocrystalline silicon solar cells achieve >26% efficiency thanks to:
• Optimized light absorption coefficients
• Extended carrier lifetime (>2ms)
• Thermal stability across operating conditions
Challenges in Silicon Machining
Processing this brittle material requires:
◼ Sub-micron surface finish (Ra <50nm)
◼ Controlled waviness (Wa <0.1μm/mm)
◼ Minimal subsurface damage
