一步一脚印的朝着自己的目标，努力前进，让梦想成真。 
在整流二极体逐渐移转至中国大陆生产之际，FORMOSA MS美丽微在台湾只能生产附加价值较高的产品方能生存，因此以萧基二极体(该产品由于漏电流较小，而且效率较高，在讲求快速的时代里，有逐渐取代传统二极体之趋势，且为整流二极体中单价最高的产品)，现有产品分类从0.1安培至三十安培均有产制，产能规划每月超过200KK从事焊接,成型,测试等之生产作业，另有多元化产品从一般、快速及超快速的二极体均有制造。 

FORMOSA MS美丽微目前的销售客户大部份以国内半导体制造商的OEM及中间电子零件贸易商为主，部份以自有品牌行销，客户遍及世界各地且广获好评,应用类别涵盖通信,车用,AI及穿戴装置等

FORMOSA MICROSEMI CO. LTD was founded on July 1996. So far, there are three chairman. The original founder and chairman of the board, madam Irene Yang.

Step by step toward your goal, work hard and make your dreams come true. 
When the rectifier diodes are gradually transferred to mainland China, they can only produce products of higher added value in Taiwan. Therefore, based on the Xiaoji Diode (due to the smaller leakage current and higher efficiency , In a fast-moving era, there is a trend of gradually replacing the traditional diode, which is the highest priced product in the rectifying diode.) The existing product categories are available from 0.1 amperes to 30 amperes each month. Capacity Planning Monthly More than 200KK engaged in welding, forming, testing and other production operations, another diversified products from the general, fast and ultra-fast diodes have been manufactured. 

At present, most of the sales customers are OEMs and intermediate electronic parts traders of domestic semiconductor manufacturers. Some of them are marketed by self-owned brands and are widely acclaimed by customers all over the world. The application categories cover communications, vehicle use, AI and wearable Device and so on.
