ABSTRACTThe first objective of this proposal is to fabricate from silicon a test platform chip (GT03) that will be used for testing of new organic semiconductors for chemical sensing and for organic electronics. With this chip it will be possible to compare directly the electronic performance parameters of the new materials with those of silicon, as the "gold standard". This chip will be particularly useful in the search for the elusive "semiconductor field-effect" in organic semiconductors. In order to achieve a broad impact in the engineering and scientific community the bare chip will be made available to interested research groups developing organic field-effect transistors and gas sensors. A uniform testing protocol will be developed that will allow comparison of properties of these materials prepared in different laboratories. It will expand the range of selective materials proposed for chemical sensing. The platform is particularly suitable for organic semiconductors that can be deposited by either solvent casting or by sublimation. The chemical sensing and electronic chips in sensing arrays that were previously fabricated separately will be combined in one chip in order to by-pass the low-yield and expensive flip-chip bonding step needed for the two separate chips. The resulting array will have CMOS electronic circuitry integrated on the same chip. It will be the smallest, fully integrated, low power sensing platform for gas sensing that could be incorporated into an existing portable electronics, e.g. cell phones, pagers PDA's, in order to create a dynamically distributed array of arrays, i.e. superarrays. The expression "dynamically distributed" implies that the location of the individual arrays in space is not predetermined and that it is continuously changing as the person carrying this enhanced personal electronics moves around. The intellectual merit of this new technology is that it enables the realization of the new, stochastic paradigm of chemical information acquisition. Recognizing that highly specialized fabrication facility, such as exists at the Georgia Tech, may not be available to most research groups working in chemical sensing field we are proposing to make the new sensing platform available to interested sensing groups in academia. Making the chips generally available would have a broad impact on the chemical sensing field. The interested groups should contact the PI (404 894 4828) or by e-mail: [e-mail].

本提案的第一个目标是从硅制造一个测试平台芯片（GT 03），将用于测试新的有机半导体化学传感和有机电子。有了这个芯片，就可以直接比较新材料的电子性能参数与硅的电子性能参数，作为“黄金标准”。这种芯片在寻找有机半导体中难以捉摸的“半导体场效应”方面特别有用。为了在工程和科学界产生广泛的影响，裸芯片将提供给有兴趣开发有机场效应晶体管和气体传感器的研究小组。将制定统一的测试方案，以便比较不同实验室制备的这些材料的性能。它将扩大用于化学传感的选择性材料的范围。该平台特别适用于可通过溶剂浇铸或升华沉积的有机半导体。先前单独制造的传感阵列中的化学传感和电子芯片将被组合在一个芯片中，以绕过两个单独芯片所需的低产量和昂贵的倒装芯片接合步骤。所得到的阵列将具有集成在同一芯片上的CMOS电子电路。它将是用于气体感测的最小的、完全集成的、低功率感测平台，其可以被并入现有的便携式电子设备（例如，蜂窝电话、寻呼机PDA）中，以便创建阵列的动态分布阵列，即超阵列。表述“动态分布”意味着各个阵列在空间中的位置不是预先确定的，并且随着携带该增强的个人电子设备的人四处移动而连续变化。这项新技术的智力价值在于它能够实现化学信息获取的新的随机范式。认识到高度专业化的制造设施，如存在于格鲁吉亚技术，可能无法提供给大多数研究小组在化学传感领域工作，我们建议使新的传感平台提供给感兴趣的传感团体在学术界。使芯片普遍可用将对化学传感领域产生广泛影响。感兴趣的团体应联系PI（404 894 4828）或通过电子邮件：jiri.
