CONCLUSION
CONCLUSION
• To minimize contamination in wafer processing.
• Particle control, wafer cleaning and gettering are some of the "nuts and bolts" of chip manufacturing.
• The economic success (i.e. chip yields) of companies manufacturing chips today depends on careful attention to these issues.
• Clean factories through air filtration and highly purified chemicals and gases.
• Wafer cleaning using basic chemistry to remove unwanted elements from wafer surfaces.
• Gettering to collect metal atoms in regions of the wafer far away from active devices.
• The bottom line is chip yield. Since "bad" die are manufactured alongside "good" die, increasing yield leads to better profitability in manufacturing chips.
