How Simulation is Accelerating AI Integration in Semiconductor Manufacturing

The semiconductor industry has forever led the League of Progress, redefining life, work, and communication. While demand for more advanced chipsets continues to rise, driven by AI, 5G, IoT, and autonomous systems, challenges associated with semiconductor manufacturing increase in dimension and complexity. The solution calls for new approaches, and here, simulation enhanced by AI comes into the picture.

Simulation technology is fundamentally revolutionising how chips are designed, tested, and manufactured. In combination with AI, it will allow chipmakers to optimise processes, save more money, and meet rising performance demands with an unprecedented level of precision. This blog gets to the nuances of this transformation, with real-world examples and a look at how the best-in-class Indian semiconductor companies and global players are driving these developments.

The Basics of the Semiconductor Manufacturing Process

Semiconductor manufacturing is very complicated and requires nanometer accuracy in many of its procedures. Some of these are:

1. Chip Design: Development of a blueprint for the desired functionality.
2. Fabrication of the wafer: Construction of transistors and interconnects on a silicon wafer using lithography, deposition, and etching.
3. Assembly and Packaging: House the chip in a package for protection while ensuring connectivity to other devices in the circuit.
4. Testing: Chip testing where the chip must function as desired under various conditions.

Each stage offers its unique set of challenges such as yield optimization, defect management, and thermal regulation. Furthermore, manufacturers must contend with increasingly smaller yet more powerful chips. In the absence of effective tools, these challenges result in astronomical cost projections along with overly delayed completion times.

Role of Simulation in Overcoming Manufacturing Hurdles

Simulation tools enable firms involved in semiconductor manufacturing to simulate real conditions but in virtual environments. They can, therefore, test analyse, and optimize any stage of the production cycle without necessitating the building of prototypes. This leads to better product quality and fast development cycles with reduced costs.

How Simulation is Game Changer in Semiconductor Manufacturing

• Process Optimization: Simulations model the production process to reveal inefficiencies and propose improvements.
  • Example: A leading semiconductor company in India used thermal simulations to optimize its high-performance processors with regard to heat dissipation, thus reducing overheating-related problems by 20%.
• Defect Detection: Simulations allow engineers to predict and prevent design and manufacturing faults.
• Material Efficiency: By optimizing material usage, simulation seeks to minimize waste so resources are effectively utilized.
• Accelerated Time-to-Market: Virtual testing has been shown to reduce significantly the time taken in design iterations so that companies manage to release products quickly.
  • Real-Life Scenario: A chipset manufacturing company in India was able to bring forward its product launch by six months by leveraging AI-based simulations to validate its designs.

AI-Based Simulations: The Game Changer

Though traditional simulations are extremely powerful, using AI elevates the capabilities of simulations to a new level altogether. AI aids in simulations with predictive analytics, adaptive learning, and real-time decision-making. This enables the simulation process to become smarter, faster, and more reliable.

Applications of AI in Semiconductor Simulations

1. Design Optimization at Scale: AI algorithms can check hundreds of millions of possible chip designs in parallel, while simulations test these designs without having to build a single prototype, reducing time to market and development costs.

Example: A leading chipset manufacturing company in India uses AI to develop a power-efficient design for IoT devices. As a result, the energy consumption is reduced by 25% as opposed to a traditional design.

2. Predictive Maintenance in Fabs: Semiconductor fabs are fitted with extremely sensitive apparatus and require constant maintenance. AI-based simulations predict when the equipment needs maintenance and, thereby, prevent sudden downtimes.

Emphasis: In Bengaluru, an India-based leading semiconductor company used AI-based simulation to find out the patterns of wear and tear of its lithography equipment and reduced downtime by 30%.

3. Yield Prediction and Yield Enhancement: The AI models analyze production data to predict yield-which is the percentage of working chips from a wafer-and suggest possible optimizations.

Case Study: A company using AI simulations for wafer inspection achieved a 98% yield rate, which remains the record for their high-density processors.

4. Real-Time Process Monitoring: AI-powered simulations of production processes track anomalies and recommend instant changes to preserve quality.

Case Study: AI Simulation in Lithography

Lithography is an integral part of semiconductor manufacturing where patterns of nanoscale are etched onto the wafers. An error or a defect at this stage would result in valuable yield loss at this stage.

• Challenge: An Indian chipset manufacturer was aligned falsely in its EUV lithography process. Traditional calibration methods were very slow and needed multiple physical adjustments.
• Solution: AI simulations created a digital twin of the lithography equipment, enabling engineers to check hundreds of thousands of parameters virtually. This resulted in achieving perfect alignment in a fraction of the time, helping save millions of dollars in calibration costs.
• Outcome: Improved production efficiency by 35% while the company considerably reduced its defect rate.

Sustainability: The Green Revolution in Chip Manufacturing

Semiconductor fabs consume vast amounts of energy and water, making them a strong environmental challenge. Today, AI simulations are a foundation of sustainable manufacturing.

How AI Simulations Help Sustainability

1. Energy Efficiency: The simulation of the processes points to such energy-intensive steps where energy usage can be reduced with the help of optimization suggestions.
2. Reducing Material Wastage: Simulation helps fabs minimize silicon and chemical waste through predictions of optimum material usage.
3. Eco-Friendly Process Design: AI-driven simulations design the manufacturing workflow so that it is in line with sustainability goals.

Illustration: A leading semiconductor firm in India used simulation to reduce water consumption associated with the fabrication process- over 100 million liters per annum.

India: Emerging as a Semiconductor Powerhouse

India has emerged as a fast-paced semiconductor hub with investments by big players from abroad and from within the country. It has outpulled many countries through its Production Linked Incentive (PLI) scheme, and a robust IT ecosystem has positioned India as a forerunner in innovation.
