SemiLEDs Corp (LEDS)

A. Company Overview

SemiLEDs Corp. specializes in the development, manufacturing, and sale of light-emitting diode (LED) chips, components, modules, and systems. The company’s products find wide applications in general lighting, medical therapy, counterfeit detection, and various industrial use cases. Additionally, SemiLEDs focuses on ultraviolet (UV) technology for curing polymers and medical/cosmetic applications, targeting niche markets such as horticulture, architectural, and entertainment lighting.

The production process leverages proprietary methods, such as epitaxial growth on sapphire wafers, culminating in the creation of LED chips that are then packaged into various components for distribution. The company’s offerings include its Enhanced Vertical (EV) LED product series, available in multiple wavelengths such as blue, white, green, and UV, catering to specific market demands.

B. Technology

SemiLEDs employs a patented manufacturing technology characterized by the integration of a copper alloy into vertical LED structures. This process begins with the growth of multiple layers of gallium nitride (GaN) on a sapphire substrate, followed by the addition of a silver reflective layer and a copper alloy base. By then removing the sapphire substrate through a laser process, the company maximizes production efficiency and cost-effectiveness.

The advantages of using a vertical design for LEDs include enhanced light output efficiency and effective heat dissipation, resulting in improved operational longevity. The high thermal conductivity of copper allows for better heat management, maintaining the performance and reliability of the LEDs. Additionally, special nanoscale surface engineering techniques are employed to optimize light extraction from the devices, further enhancing efficiency.
