“TSV IS A BUSINESS…LOOKING FOR WIDER ADOPTION!” YOLE DÉVELOPPEMENT – 13 OCTOBER 2014 • 3DIC process development has been a “hurry up and wait” scenario • Technical challenges largely overcome • Commercialization and cost challenges remain 4 2015 is cited as next inflection point
INTEGRATED METROLOGY CHALLENGE Multi-layer WLCSP package volumes are increasing rapidly with finer feature sizes. In-line metrology is critical to maintain process control. TECHNOLOGY NSX + Metrology + Discover “The Rudolph metrology capability addresses process control constraints due to its speed, accuracy, and data integrity.” – MAJOR OSAT CUSTOMER FAN OUT WLP FORECAST Source: Yole Developpement VALUE / GROWTH Inspection systems with single-layer metrology are in-line systems • 2015 will see large growth in this area as companies ramp WLP processes (i.e. TSMC InFO, ASE, STATS, SPIL) • NSX + Metrology is selected process of record at two major OSATs in 2014 5
REDUCED REVIEW CHALLENGE Our Customers’ Customers are demanding 100% defect review after inspection, which slows overall tool throughput TECHNOLOGY NSX + Discover + Discover Review INSPECTION COST PER WAFER AND RTEC MARGIN IMPROVEMENT VALUE/ GROWTH Better tool CoO through increased WPH while improving the system sales prices with high-margin software. 2D/3D PROCESS ANALYSIS FLEET MANAGEMENT ADC INSPECTION AND METROLOGY REVIEW 6
