Illuminating Profits: A Comprehensive Cost Model for LED Chip Manufacturing

insight-image


The LED chip is the core component of an LED bulb, comprising semiconductor layers that enable the free flow of protons and electrons. Found in all LED lighting fixtures—from bulbs to tubes—the LED chip fundamentally determines light quality, with variations in brightness, voltage, and wavelength. These chips are manufactured through a process called MOCVD (metal-organic chemical vapor deposition), which creates the semiconductor layers that facilitate electric flow. When an LED chip is connected to a power source, voltage is applied in both forward and reverse directions, causing electrons and holes to move within the chip and generate a current. As electrons and holes of opposite charges meet, they combine in a process called recombination. During recombination, the energy produced is less than that of the individual electrons and holes, with the excess energy converted into light, resulting in light emission. Major applications of these chips include backlighting, illumination, automotive lighting, signs, and signals.

The global LED chip market was valued at USD 31.26 Billion in 2024. According to IMARC Group, the market is projected to reach USD 81.67 Billion by 2033, growing at a CAGR of 10.70% from 2025 to 2033. The market is primarily driven by a growing preference for cost-effective lighting solutions and increasing awareness of energy conservation, which significantly boosts demand for these products. LED chips efficiently convert electricity into energy with minimal waste while providing high luminous intensity. Furthermore, ongoing technological advancements and extensive research and development (R&D) efforts have reduced the average cost of LEDs, which serves as a key growth driver. Additionally, various governments worldwide are promoting energy-efficient lighting solutions, further supporting LED chip sales. Rapid urbanization, robust growth in the real estate sector, and rising disposable incomes are also contributing to a positive global market outlook.

It is also driven by the development of effective and reliable low-ohmic contact electrodes. These electrodes help maintain a minimal voltage drop between contact materials and provide stable bonding pads for wires while maximizing light emission. Additionally, innovation has propelled market demand, with companies introducing advanced products to meet evolving needs. For example, in 2020, Osram launched its projector power series of LED chips, delivering brightness of 1000 ANSI lumens. Such advancements have broadened applications across various industries, supporting global market growth.

Case Study on Cost Model of LED Chip Manufacturing Plant

One of our clients reached out to us to conduct a feasibility study for setting up a large-scale LED chips manufacturing plant. We developed a comprehensive financial model for the setup and operation of a proposed LED chip manufacturing plant in India. This plant is designed to produce approximately 336 wafers, or around 12,000 LED chips per day.

Manufacturing Process: LED chip manufacturing spans several stages: epitaxial growth, chip fabrication, wafer processing, and backend processing. Epitaxial growth uses MOCVD technology to form layers in the LED structure, such as the GaN buffer and MQW active region, enhancing LED performance through improved process control, gas flow, and temperature uniformity. In the chip fabrication stage, semiconductor layers are patterned, and metal layers are deposited to create electrical contacts, followed by surface texturing to improve light extraction. Wafer processing includes p-contact layer formation, mesa etching for n-GaN exposure, and metallization, providing connections to the LED package. The wafer is then thinned, usually by grinding and laser lift-off. Backend processing involves die singulation and testing. During laser scribing, the wafer is prepared for individual die separation with precision. Next, film frame mounters hold the wafer during singulation, while die expanders stretch it for testing and placement. This process enables efficient LED chip production, ensuring consistent quality and performance.

Manufacturing Process

Mass Balance and Raw Material Required: The primary raw materials used in the LED chips manufacturing plant include acetone, AuSn solder, GaN etchant, developer, etcher Ag, etchant metal, zeolite slurry, hydrogen gas, nitrogen gas, ammonia, oxygen gas, and various other components. For a plant producing wafer (equivalent to 12,000 LED chips), the required quantities are as follows: acetone (467 g), AuSn solder (0.3 g), GaN etchant (192 g), and other materials (8,651 g).
