KLA Corporation is an original equipment manufacturer (OEM) of process diagnostics and control (PDC) equipment and yield management solutions required for the fabrication of semiconductor integrated circuits (ICs) or chips. The company has a comprehensive portfolio of products addressing each major PDC subsegment'photomask (reticle) inspection, wafer inspection/defect review and metrology.Reticle production is vital to the semiconductor device formation process. Reticles are used to control the precise deposition of materials onto the wafer, which ultimately change its chemical characteristics, imparting specific functionalities to the ICs thus created. Inspection and metrology tools measure the quality of the reticles, helping to improve reticle production yields. As a result of the broader applicability of semiconductors, shrinking form factors and increasing functionalities of individual chips, reticle design and production are growing in importance.
