SemiLEDs Corporation develops, manufactures, and sells light emitting diode (LED) chips and LED components. The company’s products are used primarily for general lighting applications, including street lights and commercial, industrial and residential lighting. Its LED chips might also be used in specialty industrial applications, such as ultraviolet (UV) curing of polymers, LED light therapy in medical/cosmetic applications, counterfeit detection, LED lighting for horticulture applications, architectural lighting and entertainment lighting. The company sells blue, white, green and UV LED chips to a customer base that is concentrated in a few select markets, including Taiwan, the United States, and China (including Hong Kong). The company also sells its ‘Enhanced Vertical’ (EV) LED product series in blue, white, green and UV. The company sells its LED chips to packagers or to distributors, who in turn sell to packagers. In addition, the company packages a portion of its LED chips into LED components, which the company sells to distributors and end-customers in selected markets. The company also contracts other manufacturers to produce for its sale certain LED products, and for certain aspects of its product fabrication, assembly and packaging processes, based on its design and technology requirements and under its quality control specifications and final inspection process. The company’s major subsidiary is its wholly owned operating subsidiary, SemiLEDs Optoelectronics Co., Ltd. (Taiwan SemiLEDs), where a portion of the company’s assets are held and located; and where a portion of the company’s research, development, manufacturing, marketing and sales activities take place. Taiwan SemiLEDs owns a 100% equity interest in Taiwan Bandaoti Zhaoming Co., Ltd., which engages in the research, development, manufacture, marketing and sale of LED components. As of August 31, 2015, the company also owned a 93% equity interest in Ning Xiang Technology Co., Ltd. (Ning Xiang), a company engages in the design, manufacture and sale of lighting fixtures and systems. As of August 31, 2015, the company owned a 33% interest in SILQ (Malaysia) Sdn. Bhd., a joint venture established in Malaysia to design, manufacture, and sell lighting fixtures and systems. Products The company’s core products are LED chips and LED components, as well as lighting products. LED components have become the most important part of the company’s business. LED Chips The company produces various blue, white, green and UV LED chips, including its EV LED product series, ranging from chip sizes of 380 microns, or µm, by 380µm to 1520µm by 1520µm. The company sells its LED chips to packaging customers or to distributors, who in turn sell to packagers. In 2014, the company launched its Enhanced Flip Chip (EF) LED series and newest line of white chip scale packages, the ReadyMount Enhanced CSP series. The EF series launched with the EF-B40, a blue 40-mil flip chip that simplifies the packaging and integration process by eliminating wire-bonding while increasing both lumen-density and decreasing the lumen-per-dollar value proposition while enabling packagers to use standard surface mount assembly techniques. In March 2015, the company announced its Phosphor Converted (PC) LED chip series, including PC Red, PC Green, and PC Amber, in a 40mil (1mm × 1mm) chip that combines with the company’s ReadyWhite phosphor technology to minimize blue pass through in its product and therefore allow more options for the company’s customers in these color ranges. LED Components The company packages a portion of its LED chips into LED components for sale to distributors and end-customers in selected markets. The majority of its LED components use chips that are approximately 860mm by 860mm, focusing on high wattage (>3W) applications. The company’s packaged products utilize high thermal conductivity aluminum nitride as the substrate and could be categorized into four different groups, such as UV, multi-channel emitters (MCE), automotives and specialty lighting. Besides the standard products, the company provides customization service for all market segm
