Product mix planning in semiconductor manufacturing

To cope with product demand and price fluctuations and rapid technology transition, many semiconductor manufacturers have broadened their product scope to wider ranges of memory and logic devices in recent year's. Product mix planning emerges as a critical business capability to exploit market opportunities. This paper focuses on product mix planning in a foundry manufacturing environment. Issues discussed include levels of planning granularity, mix planning and bottleneck-based analysis. A software system has been implemented that provides both product mix solutions and sensitivity information of product price and tool capacity. Used as a planning tool, the system will improve fab agility under dynamic market conditions.
