Patent ID: 7739305

Claim:
A network appliance, comprising: a database stored in a memory; a file capture module configured to obtain manufacturing data files transmitted via a first network and to load data from the manufacturing data files into the database; a data processing module configured to retrieve data from the database responsive to data selected with a first set of fields, to chart the data retrieved responsive to indices selected by a client system using a second set of fields, and to output a graph of the data charted to a web server, the web server sending the graph to the client system via a second network, and wherein the first set of fields comprises a first field and second field of the first set of fields; wherein the data processing module is further configured to display respective sets of selectors corresponding each of the first and second fields, and in response to user selection of a selector in the respective selector set of the first field, the data processing module displays only selectors of the respective set of selectors of the second that are hierarchically related to the selected selector; wherein the data is loaded into respective tables of the database, the tables being associated with the first set of fields; wherein the data loaded is stored in the tables according to a wafer identifier for a wafer, a parameter, and a data set for rows of the tables; and wherein the data set includes values associated with a parameter for the IC dies on a die-by-die basis for the wafer.
