This research proposes that IC foundries can provide multiple cycle time product service in order to meet the customer requirements. Multiple cycle time product service is that, wafer lots are assigned different committed manufacturing cycle time based on customer’s demands. For example, wafer lots are groups into three classes: shorter cycle time lots, regular cycle time lots, and longer cycle time lots. Customers can place their orders with a particular cycle time and price. Based on this idea, this research proposes a systematic approach to determine various committed cycle time and the corresponding relative prices. This research uses the APS software, Adexa MCP, and the semiconductor manufacturing line simulator, ASAP, to determine the appropriate level of throughput and the reasonable committed cycle time with a given product-mix. Then, we use ASAP to analyze the impact of different percentage of shorter cycle time lots on the following cases: (1) the decrease of throughput with the given committed cycle time and a given delivery rate; and (2) with the given throughput, the decrease of lots that are made within the committed cycle time. Then we define a new committed manufacturing cycle time with that a given delivery rate can be satisfied. Based on these impacts, we can define the relative prices among various cycle time products.
