摘要

隨著電子產品日趨精密，半導體製程日趨微小，不適當的ESD (Electro Static Discharge) 處理所產生的危害卻反而與日俱增。而想要避免ESD的危害，除了需對將生產環境與設備做出適當的ESD措施之外，最難管控的就是在其中做生產工作的操作人員。 這些操作人員最容易因不慎而產生疏失，雖然公司訂定了縝密的標準作業流程，也全面要求並實施，但是只要人員一個不經意的疏忽，依舊會造成重大的損失。因此本文提出兩個研究貢獻。首先，本文提出一個Zigbee無線ESD手環，包含硬體與軟體實作。讓工廠操作人員配戴以監管ESD不會對所生產的產品造成危害。其次，手環中Zigbee晶片軟體可對於配戴者進行感測定位，判斷其是否處於本文所規範的ESD靜電安全防護區的範圍。若中途有離開的情況發生，則採取進一步作為防止安全環境惡化，導致危害到產品生產的品質。實驗結果驗證ESD手環硬體運作良好，包含無線訊號、ESD監控、與設備對於人體安全測試。軟體驗證可準確判定配戴者位置接近於預先設定的參考定位點，確保人員處於安全區域。因此，本文提出的無線ESD手環，可充分滿足ESD安全監控需求。

As the precision requirements of manufacture process for electronic products and semiconductors become critical and strict, impropriate treatment of Electro Static Discharge (ESD) can cause more serious damage on sophisticated products. In order to avoid ESD damage, the manufacturers have to deploy effective ESD protection systems in their manufacturing environments. However, human error is very difficult to control for the production process protection. Although several rules and standard operation procedures have been set and the staffs have to follow and implement them strictly, the inadvertent carelessness can still cause significant losses. This paper presents two major contributions. First, this paper presents a Zigbee wireless ESD wearable device, including hardware and software implantations. To monitor ESD risks, a factory operator can wear the device for preventing ESD damages from the manufacturing product. Second, the Zigbee software in the device can locate the position of the operator wearing the device to ensure the operator staying in the safe area. In case of leaving the safe area, the device can notify this event for preventing ESD damages upon manufacturing products. Experiment results validate the operations of the device hardware, including wireless transmissions, ESD monitoring, and human safety testing. The software evaluations show the location of the operator wearing the device can be determining correctly nearby the pre-defined reference location in order to ensure the location is inside the safe area. Therefore, the proposed wireless ESD wearable device can fully satisfy the demands of ESD risk control.
