Wafer demand for semiconductors by device type tends to be evenly split over time.
Logic/MPU and memory ICs stay evenly balanced due to system architecture. The same is true for analog ICs and discrete semiconductors.
Better Intelligence=Better Decisions=Better Results
VLSIresearch has always driven to deliver data and services with the most advanced methods, such as the internet and dynamic databases.
Its innovations include being the first to use demand-based forecasting; the first to model semiconductor inventories in forecasts;
the first to use cost-of-ownership models for evaluating equipment; the first to
perform customer satisfaction surveys; the first semiconductor industry research firm to apply capacity and inventory models in forecasting;
the first to use pricing data to capture supply demand imbalances.
Silicon demand wafer size favors larger wafer sizes. 300mm already accounts
for almost two-thirds of all wafer fab manufacturing and this will continue to grow through 2015. 450mm will account for 14% of all chip production by 2020.
Trends by Node
Silicon wafer demand for chip making continues to favor tighter nodes with greater growth. Some say Moore's Law is dead,
but the data proves it wrong. Devices with dimensions smaller than 20nm will consume more than half of all silicon by 2020.
