Chip Manufacturing

The Company's portfolio of inspection and metrology products, and related service, software and other offerings, helps chip manufacturers manage yield throughout the entire semiconductor fabrication process-from research and development to final volume production. These products and offerings are designed to provide solutions to help its customers to manage their development and production ramp cycles.

Front-End Defect Inspection

KLA-Tencor's front-end defect inspection tools cover a range of yield applications within the IC manufacturing environment, including research and development; incoming wafer qualification; reticle qualification, and tool, process and line monitoring. Patterned and unpatterned wafer inspectors find particles, pattern defects and electrical issues on the front surface, back surface and edge of the wafer, allowing engineers to detect and monitor critical yield excursions. The defect data generated by the Company's inspectors is compiled and reduced to relevant root-cause and yield-analysis information with its suite of data management tools. By implementing its front-end defect inspection and analysis systems, chipmakers are able to take corrective action. Its products include 3900 Series, 2930 Series, Puma 9980 Series and Surfscan SP5XP. The 3900 Series broadband plasma patterned wafer inspection systems incorporate a high resolution deep ultra-violet (DUV) wavelength range and optical inspection speed, supporting defect discovery and debug of advanced IC processes. The 2930 Series broadband plasma patterned wafer inspection systems are used to discover and monitor defects related to design or process issues, supporting advanced IC development and ramp. The Puma 9980 laser scanning patterned wafer inspector provides defect type capture for high throughput production ramp monitoring across a range of IC applications. The Surfscan SP5XP unpatterned wafer inspection system utilizes extended deep ultra-violet optical technologies early detection of process and tool excursions.

In the field of patterned wafer inspection, the Company offers its 3900 Series (for high resolution broadband plasma defect inspection); 2930 Series and 2920 Series (for broadband plasma defect inspection); Puma 9980 Series, Puma 9850 Series and Puma 9650 Series (for laser scanning defect inspection); 8 Series systems (for high productivity defect inspection), and CIRCL cluster tool (for defect inspection, review and metrology of all wafer surfaces-front side, edge and back side). In the field of unpatterned wafer and surface inspection, the Company offers the Surfscan SP5 Series and Surfscan SP3 Series (wafer defect inspection systems for process tool qualification and monitoring using blanket films and bare wafers), and the SURFmonitor (integrated on the Surfscan SP5 and Surfscan SP3 Series), which enables surface quality measurements and capture of low-contrast defects. For reticle inspection, the Company offers X5.2, X5.3 and Teron SL650 Series products, which are photomask inspection systems that allow IC fabs to qualify incoming reticles and inspect production reticles for contaminants and other process-related changes.

Defect Review

KLA-Tencor's defect review systems capture high resolution images of the defects detected by inspection tools. These images enable defect classification, helping chipmakers identify and resolve yield issues. KLA-Tencor's suite of defect inspectors, defect review and classification tools and data management systems form a solution for finding, identifying and tracking yield-critical defects and process issues. The Company has introduced the eDR7280, an electron-beam wafer defect review and classification system that utilizes imaging and automatic defect classification capability to identify detected defects and produce a representation of the detected defect population.

Advanced Packaging Process Control

KLA-Tencor offers standalone and cluster inspection and metrology systems for various applications in the field of advanced semiconductor packaging (at the middle and back-end of the semiconductor manufacturing process). Its CIRCL-AP all-surface inspection, metrology and review system supports advanced wafer-level packaging processes, such as 2.5D/3D IC integration using through silicon vias (TSVs), wafer-level chip scale packaging (WLCSP) and fan-out wafer-level packaging (FOWLP). Used for packaging applications associated with LEDs, MEMS, image sensors and flip-chip packaging, its WI-22x0 Series products focus on front side wafer inspection and provide feedback on wafer surface quality, quality of the wafer dicing, or quality of wafer bumps, pads and pillars. Its component inspector products, the ICOS T830 and ICOS T640, inspect various semiconductor components that are handled in a tray, such as microprocessors or memory chips.
