摘　　要：通过理论分析得出硅双结型色敏器件中掺杂浓度和两个结的结深是影响光谱响应范围的主要因素。通过选择不同的器件结构和工艺条件 ,得到了色敏器件对蓝紫光的响应 ,完成了全色波段硅双结型色敏器件的研制。Theoretic analysis results show that the doping concentration and junction depth are main factors for the range of spectrum response of Si color sensor with double PN junction. Purple-blue sensitivity of Si color sensor with double PN junction is gained through appropraite selection from different structures of devices and technology conditions, on the base of which a device for panchromatic wave band has been fabricated.
