Question 1

?How has Moore's Law influenced the development of VLSI technology over the past few decades

Accepted Answer

Moore's Law has significantly influenced the development of VLSI (Very Large Scale Integration) technology by driving exponential growth in the number of transistors that can be placed on a single chip. This doubling of transistor count approximately every two years has led to remarkable increases in computational power and efficiency while reducing costs. As a result, it has enabled the development of more powerful and compact electronic devices such as microprocessors, memory chips, and various digital components. Innovations in semiconductor manufacturing processes, such as advancements in photolithography and materials science, have been fueled by the pursuit of maintaining Moore's Law, pushing the boundaries of miniaturization and performance. This relentless progression has made modern computing, smartphones, and advanced digital systems possible, transforming industries and everyday life.

Question 2

?What are the primary challenges faced in continuing to follow Moore's Law in VLSI technology today

Accepted Answer

The primary challenges in continuing to follow Moore's Law in VLSI technology today include:

Physical Limitations: As transistor sizes approach atomic scales, quantum effects like electron tunneling become significant, making it difficult to maintain reliable operation and further miniaturization.

Heat Dissipation: Increasing the number of transistors on a chip leads to higher power densities and heat generation. Efficiently managing and dissipating this heat is a major challenge to prevent thermal damage and ensure performance.

Manufacturing Complexity: Advanced fabrication techniques, such as extreme ultraviolet (EUV) lithography, are required for smaller nodes, which are expensive and complex to implement, raising the cost of manufacturing.

Material Limitations: Traditional silicon-based transistors are reaching their performance limits. Developing new materials and transistor architectures, like FinFETs and gate-all-around transistors, are necessary but pose significant technical challenges.

Economic Viability: The cost of research, development, and manufacturing increases exponentially with each new generation of technology. Balancing these costs while maintaining affordable consumer products is increasingly difficult.

To address these challenges, the industry is exploring alternative approaches like three-dimensional (3D) stacking, neuromorphic computing, and quantum computing, which may complement or eventually replace traditional VLSI technology.
