METROLOGY � INLINE QUALITY PLATFORM
Manz IQ tester concept
Combination of (multiple) test tools to build a fully integrated tester with high-level result analysis, summary & classification General Scope Quality testing for ,,good / ,,not good decisions Discovery of systematic failures and process drifts on a short time scale Designed for inline operation: Different strategies for full substrate mapping at inline throughput

MANZ AG

Our strength / your benefit
Very strong development team due to specialists in photovoltaics, automation, laser scribing, wet chemistry, vacuum machines and vision & metrology Combine state-of-the-art measurement technologies into a single tester with a well defined interface Perfect integration of Manz IQ testers with other Manz process tools High quality due to field-approved components Low cost & high flexibility due to modular concept

IQ Inspect � 100% OPTICAL AREA INSPECTION
What it does
Inspect: Detect features that deviate from a defined reference Measure: Record & evaluate known substrate properties Features Uses Dr. Schenks leading edge inspection technology 100 % defect & inhomogeneity inspection High precision measurement of panel properties Robust setup with industry proven components

MANZ AG

Very powerful and intuitive software

Applications
Glass inspection (edge) defects and contaminations Glass measurement size, positions of glass features Coating inspection layer defects, homogeneity monitoring Scribe inspection discontinuities, under- & over scribes Edge deletion inspection edge deletion residues Final inspection encapsulation & lamination defects

LASER SCRIBING P1 (UV vs IR)
Past: Manz focused on SnO, scribing with IR
Now and Future: Manz will provide P1 with UV as well

P1 scribing with IR

P1 scribing with UV laser source



Max scribe speed 600mm/s limitation in process speed > 25MOhm insulation



No melt zone / no HAZ Proper ablation Clean spot ground / No substrate damage Wide range of scribing parameters No influence of Rep. Rate and Overlap

LASER SCRIBING WITH IPCS
IPCS = Inline Precision Control System

Dead area
P2 & P3 are written with respect to P1 parallel to within �10�m - every line! minimal dead area (down to 160 �m possible)

Throughput
approx every 15 cm one laser module fast substrate input and output Cost of Ownership

high machine throughput & utilization
tailored laser sources Process robustness process optimized laser sources with various power levels Also works for BIPV modules

IPCS � CUSTOMER BENEFITS
Highest scribe accuracy (�10�m) Lowest dead area in the market (can be as small as 160�m, depending on scribe widths)

MANZ AG

P2/3 scribing T-independent
referencing to scribes, no reference marks needed minimized secondary time no AC-unit required reduced investment costs and CoO



Customer friendly module exchange
minimized systems downtime

Laser sources for all relevant layers available (different power level)

IPCS can be used also for BIPV
scribing
high throughput customized spot size various design pattern possible
2011-07 17

IPCS � EFFICIENCY IMPROVEMENTS
Safe time! � minimize cycle time
Fast load and unload of substrate No scribe alignment to reference marks needed Minimal secondary time and maintenance efforts one block design of laser optic module (IPCS) Multiple laser sources for highest throughput (up to 8 lasers @ Gen 5 panels)
