WP 40 Lot Expansion Project 排貨流程及策略介紹Dispatch flow and strategy Introduction Content Dispatch Purpose strategy Terminology introduction Traditional manual dispatch operation flow Now Dispatching Engine operation flow D-Engine’s Benefit Basic dispatch strategy concept D-Engine architecture default dispatch strategy OPI D-Engine performance demo Dispatch Purpose strategy Modeling integrated dispatch rule in dispatching system in order to systematized. Purpose: Achieve monthly/quarterly production plan , create the maximum revenue reduce production cycle time , inventory On time delivery Strategy : Enhance line balance Bottleneck machine utilization ? Move target control Terminology IC flow Lot (晶圓批) WIP : Work in progress(在製品) Move (晶片移動量) T/R :Turn Rate (晶片週轉率) Cycle time(生產週期) Wafer In/Out(晶片投入量/晶片產出量) Production Plan (生產企劃) Lot priority class (晶圓批優先權) IC flow Move definition T/R Definition T/R : 週轉率 Definition : T/R = Move / WIP T/R = Passed Steps count / Day Example : Cycle time definition T/R Cycle time 例如 0.15 um 256MDDR TR/Day =6.5,total step count=620 T/R cycle time = 620/6.5= 95 day Out put Cycle time 例如 Lot1 2003/07/01 07:30 投入 , 2003/09/01 07:30 產出 Out put cycle time = 31+31 =62 day In-line cycle time Fab production Plan Master production plan Lot priority class Priority : 優先度 Priority class : 1 : Q-time short lots ie : WJ - RGP 2: UQTAT Lots. : Super Hot lots 3: QTAT Lots: need to be hurry up. 4: STD lots need to be quick. 5: STD lots. 6: STD lots can be little late.
