JMP Yield Application: Yield Enhancement and Fab/Foundry Process Optimization
Using JMP’s rich graphical capabilities, customizable JSL code, and ODBC database connectivity to build a yield analysis application
Hyde F. Miller HydeMiller Sr. Manager, Yield Enhancement and Fab/Foundry Process Optimization, Intersil Corp 9/16/14
Key Features in JMP Useful for Building a Custom (Yield Analysis) Application
Scripting (JSL) - Facilitates fully customizable application to meet the exact business needs
Database connectivity (ODBC) - Allows direct pull of specific data from existing data warehouse
Graphical Analysis - JMP provides a rich suite of graphical tools to display results and provide insight
Multiple element reports - A single graph can provide a lot of information. Even more so, a group of graphs and analysis results can tell a more complete story.
Interactive display elements - Add drill-down capability to explore the next logical question of what is driving yield trends.
Add-ins -Easy to deploy across the organization

Example JSL ODBC Code
Database Connection String dsn_string = "DSN=MIDAS;PWD=;DBQ=MDS1;"; Hint: to determine your string, open a database table using the menus (File ->Database->Open Table). Then edit table source (hot spot on table).
SQL Commands sql_1 = "select * from MEL.LOT MEL_LOT, MEL.LOT_OPERATION_GROUP MEL_LOT_OPERATION_GROUP where MEL_LOT.LOTID in ('X2T7JB','X2T7L','X2T7LA') and MEL_LOT_OPERATION_GROUP.operation_group_nm = 'TEST' and MEL_LOT.LOTID=MEL_LOT_OPERATION_GROUP.LOTID"; sql_2 = "select * from MEL.LOT MEL_LOT where ROWNUM <= 5";
Open Database Method (one-shot) dt_1 = Open Database(dsn_string, sql_1, "First Table", invisible); dt_2 = Open Database(dsn_string, sql_2, "Second Table"); Hint: this method is best for debugging SQL code
Demonstration - Points Made During Demo
Be luxurious. Each chart provides information. A collection of charts provides insight.
Systematize best practice. Take input from top experts within the company, how would they do it? Then build in that expert knowledge so everybody does it that way. Then perfect over time based on lessons learned.
Utilize many JMP capabilities
Trend lines (linear fit)
Smoother Trend (interactive)
Color coded points
Statistical results - tabular data
By capability - Example: yield by facility
Linked graphs and brushing
When script stops, you still have full capabilities of JMP
JMP has a variety of graphical tools. Find to one that best demonstrates the data. For example, using Graph Builder trellis plots for wafer maps.
Custom design application to match specific business requirements (difficult to do with out-of-the-box tools).
