    • Electronic assemblies, especially one containing volatile memory, used a flexible membrane with conducting lines which acts as an intrusion sensor against chemical and mechanical attacks. The lines are fabricated from inherently conducting polymers which are solution processed and directly patterned. The material was applied to a flexible polymer film by spin coating and patterned by application of a resist, followed by exposure/development of the resist and transferring the image into the polyaniline by reactive ion etching techniques. The conducting lines have high conductivity, tranparency properties which made them difficult to detect and possess excellent adhesion to the substrate film, as well as to the potting material which enclosed the structure. They also offered lightweight advantages over conventionally filled materials. These materials can also be used in conjunction with conventional conductor materials to further enhance protection against intrusion by sophisticated mechanical means.
    • 电子组件,特别是包含易失性存储器的组件,使用具有导线的柔性膜,其作为防止化学和机械攻击的入侵传感器。 线由固溶导电聚合物制成,这些聚合物经过溶液处理并直接图案化。 通过旋涂将该材料施加到柔性聚合物膜上并通过施加抗蚀剂进行图案化,然后曝光/显影抗蚀剂并通过反应离子蚀刻技术将图像转移到聚苯胺中。 导电线具有高导电性,透明性,使得它们难以检测并具有优异的与基底膜的粘附性,以及封闭该结构的封装材料。 它们还提供比常规填充材料轻的优点。 这些材料也可以与常规导体材料结合使用,以进一步增强防止通过复杂的机械手段侵入的保护。
