At USCXM, about 26% of all reticle inspections are Incoming Qualification Control (IQC) inspections before moving the reticles into the production line. Originally, all these reticles needed to be dispatched to the inspection tool for manual recipe setup before reticle inspection could be started. Engineers had to change the Factory Automation (FA) mode from “online remote” to “local”, which would break the FA process. For typical reticles, operators would spend about 15 minutes for online recipe creation while for some special reticles like multi-layer reticles, less-experienced operators would need much more time for creating a suitable recipe, thereby adding to the cycle-time and cost of operation. To overcome these inefficiencies, a new offline setup feature called Systematic Auto Recipe Creation (SARC) was developed on KLA X5.3™ reticle inspection tools for seamless use with FA mode. Subsequently, the Reticle Management System (RMS) in USCXM was upgraded to contain all the necessary information for recipe creation. As shown in the flow in Figure 4, reticle information such as barcode, layer number, die size, die pitch, alignment mark coordinates, etc. are automatically stored in the RMS system. The system allows users to fill-in specified templates and settings. Once users input the required information for a recipe, the system creates three CSV files and sends them to the X5.3 inspection tool, and also informs Equipment Automation Programming (EAP) to send standard SECS command for recipe creation. Once the X5.3 tool receives the creation command, it generates the recipe based on the three CSV files and sends feedback about the recipe creation result to EAP and RMS system.
