以五個利潤導向維度提升產品開發績效構面之探討

Promote the study of the performance factor of the product

development by five profit orientation dimensions

Abstract

This research is with “five profit oriented dimensions (the development time/developing cost of the product quality/product cost/product/development capability)” skill, aim at light – emitting diode (LED) domain up of the new product development does research, with development of five directions to inquire into the development performance of domain.

This research hopes to reach the following object:

„ Creating the Taiwanese LED industry product develops performance beacon and determinant of management.

„ Assessment also more Taiwanese LED industry develop the performance of the performance beacon and the determinant of movable management in the product, can help an each company continuous improvement by the beacon compare.

„ Data and data gained according to the assessment process carry on analysis to understand between determinant and each performance beacon of incidence degree, for the purpose of help participate a company to promote to have the usage will of the performance beacon of interest to seemly availably. Provide related analyzing result and suggestion, make a firm by with improve the own product develop creative dynamics of management.

Study result display, the amount which develops expense invest is five profits to lead to one of the most important items, sing a key most and influencing the most deeply the most wide factor. Developed design to put into more many resources in the early years, its product quality usually stabilized, and its price of article/efficiency/manufacturing process' capability's also sing developing have already decided that product 80% destinies then in the early years; The product sells of good or not, with whether can duct into a market (Time to market) to also have important correlation in good time, and this part also with development resource of the invest is more vitally related. Can also find from the comprehensive analysis of questionnaire, the domain universe all has equal expectation to also value very much to the developments, but to development of controlling of capability and progress, mostly present impotence, acquire to another material cost high - low also value very much, however is visited a firm universe to light - emitting diode domain of future, respond mostly maintain positive viewpoint.

2. 製造流程：

上游的產品為單晶(single crystal)、磊晶片(epitaxy wafer)。單晶是作為磊晶成長用之 基板(substrate)，磊晶片是利用多種磊晶成長法，在基板上成長不同材料層後的產品。將 上游磊晶片製作電極(Metallization)後，進行平台蝕刻(mesa etching)，再切割此晶片，最 後崩裂成單顆的晶粒(Dice)。下游封裝業是將崩裂後的晶屋(此製程稱為 Wire bond)，置 入灌有樹脂的模具中，待樹脂硬化粒用銀膠黏著在導線架(leadframe)前端(此製程稱為 (die bond)。再以金線分別接合在黏著的晶粒與另導線架後取出剪腳即為成品。封裝完成 後的 LED 產品在可見光產品方面有燈泡型（lamp）、數字顯示型(digit display)、點矩 陣型(dot matrix)、表面黏著型(surface mount)等。

主要原理是經由氣流傳輸三五族化合物到磊晶基板上，再加以控制氣流及時間，藉 由氣體管路系統的特殊設計，並降低成長速率，達到磊晶成長的需求。

3. 金屬有機氣相磊晶成長法(Metal Organic Vapor Phase Epitaxy, MOVPE) 4. 分子束磊晶成長法(Molecuiar Beam Epitaxy, MBE)
