[0058] 本发明提供的生物传感模块用于感测目标物体输入的生物信息。 较佳地， 所述 生物传感模块全部形成在一生物传感芯片 (Chip)中。 具体地， 所述生物传感芯片 包括生物传感裸片 (Die)和静电传导件。 所述生物传感裸片包括存储电路， 所述 存储电路用于存储数据。 所述数据例如为所述生物传感芯片中的电路的初始化 数据、 产品的型号等等。 所述静电传导件部分或全部位于所述生物传感裸片上 。 较佳地， 所述静电传导件位于所述存储电路的正上方， 在存储电路的上方形 成凸起部或尖端， 并直接或间接连接至地， 以泄放静电。

[0070] 需要说明的是， 当导线的一端或两端形成在生物传感裸片的一侧或两侧吋， 所 述导线的一端或两端并不是形成在所述生物传感裸片上。 例如， 当生物传感芯 片采用球栅阵列封装 (Ball Grid Array Package,简称 BGA)吋， 所述生物传感芯 片进一步包括一电路板， 所述生物传感裸片与所述静电传导件形成在所述电路 板与所述封装体之间。 所述导线的一端或两端可形成所述电路板上。
[0071] 由于生物传感芯片的封装方式有多种， 例如， 方形扁平无引脚封装 (Quad Flat No-lead Package，简称 QFN) , 对应地， 所述生物传感芯片可不包括所述电路板 , 而是在生物传感裸片周围形成有引线框 (Frame)。
