中文摘要
|
發光二極體(Light Emitting Diode, LED)屬於半導體元件,具有體積小、壽命長、耗電量小等特性,已普遍應用於3C(Computer, Communication and Consumer electronics)產品指示器與顯示裝置,LED更是台灣光電產業中最具競爭力的產品之一。紅、綠、藍(RGB)三原色LED可以合成彩色,使得LED的應用範圍大幅增加,然而三原色LED在原LED Chip上測試之波長(Wavelength)與LED於後段封裝後之Lamp後之波長(Wavelength)並不相同,差異之主要原因爲兩處之工作溫度不同,導致波長偏移。本研究運用線性迴歸(Linear Regression)預測紅光Lamp波長,推導出Chip波長對Lamp波長影響之線性迴歸方程式,接著考量波長測試儀器之解析度(Resolution)正負範圍值,以最大解析度範圍值下之線性迴歸方程式作爲管制上下限,再依照客戶波長規格經由多線性迴歸方程式運算之結果,挑選出符合客戶封裝規格的LED Chip,如此減少可能造成的波長偏移的LED Chip 出貨,提升顧客滿意。

英文摘要
|
Light Emitting Diode (LED) has the characteristics of small-size, long-life, and electricity-saving. It is widely used in 3C (Computer, Communication and Consumer Electronics) devices and products. Furthermore, the LED industry is also one of the industries which have high competitiveness in global market for Taiwan. The manufacturing process of LED is similar with that of semiconductor. It composes of front-end and back-end processes. LED wavelength determines its quality level. However, LED wavelength may shift when it moves from the front-end to the back-end process. In practice, it is found that the wavelength of LED in chips in the front-end process and that of LED in lamp in the back-end process are different. The shift is caused by the difference of temperature in the front-end and back-end production process. In this research, linear regression model is constructed and employed to predict the red wavelength in lamp by the red wavelength of LED in chips. By regression models, LED manufacturers can select chips that will fit customer requirements after back-end processes and avoid the wavelength shift phenomenon when LED chips are shipped to customers.
