1. The Process flow for fabrication the resister IC. Step I: The Beginning-Choosing a substrate Before actual wafer fabrication, we must choose the starting wafers. The major choices are the type (N or P), resistivity, and orientation.By hope

Photolithography. Outline. Motivation History Photolithography Methods and Theories Preparation and Priming Spin-Coating Photoresists Soft-baking Mask Alignment and Exposure Developing Hard-baking References. Motivation. Key top-down manufacturing technology Applications:
PhotoLithography. The art of the Small. Photolithography. • Photo-litho-graphy: lati n: light-stone-writing • Photolithography: an optical means for transferring patterns onto a substrate. • Patterns are first transferred to an imagable photoresist layer .
Photolithography. Why Photolithography. Low cost IC manufacturing Due to large number of lithographic steps needed in IC manufacturing, lithography typically accounts for about 30% of cost of manufacturing. Photolithography cost minimize result in low cost IC
Photolithography. PEOPLE Program. How is Lithography Related to Computers?. Computer chips are made using photolithography Instead of drawing with a sharp tip, it uses light to transfer a tiny pattern from a photomask to a light-sensitive chemical. Packaging.
Photolithography. D. Boolchandani Department of ECE Malaviya National Institute of Technology Jaipur. Photolithography. In a microelectronic circuit, all the circuit elements (resistors, diodes, transistors, etc.) are formed in the top surface of a wafer (usually silicon).
