文件:Yageo TVS產品異動通知

DESCRIPTION:
To further advance our semiconductor product line, we are transitioning our TVS medium and high voltage (11V-220V) single-die products from the DB to the PG fabrication process. This strategic move primarily involves refining the glass passivation technique to enhance the overall performance of our products. The process focuses on optimizing the glass layer within the die groove, ensuring it does not interfere with the die separation process, while maintaining the electrical characteristics of the devices and ensuring there is no compromise on performance metrics.
Please be informed that this change will be phased in gradually. Starting from October 1st, shipments will include products manufactured using the PG process. The specific part numbers affected by this transition will be detailed in an accompanying attachment for your reference.
Enclosed is a comparative visual representation depicting the modifications pre and post-optimization. This elucidates the enhancements made and reaffirms our commitment to product excellence and reliability. We believe this proactive approach in communicating changes demonstrates our dedication to transparency

描述：

為了進一步提升我們的半導體產品線，我們正在將TVS中高壓（11V-220V）單晶產品的製程從DB製程過渡到PG製程。這一戰略舉措主要涉及改進玻璃鈍化技術，以提升產品的整體性能。該製程側重於優化晶圓槽內的玻璃層，確保其不影響晶圓的分離過程，同時保持設備的電氣特性，確保性能指標不受影響。請注意，此變更將逐步實施。從10月1日起，出貨產品將包括使用PG製程製造的產品。受此過渡影響的具體零件號碼將在隨附的附件中詳細列出，供您參考。附件中包含了一個前後優化的對比視覺呈現，這清楚的展示了所做的改進，並再次強調了我們對產品卓越性和可靠性的承諾。我們相信，這種主動的變更溝通方式體現了我們對透明度和客戶滿意度的重視。
