A new non-linear quadratic programming Bayesian prestack three-terms inversion method is developed; Firstly, this method is based on Bayesian parameter estimation theory, Gaussian distribution is used for likelihood function and modified Cauchy distribution is used for prior distribution; Secondly, covariance matrix is used to describe the degree of correlation between the parameters; rock physics relations are used to constrain the inversion results; at last, this method is transformed into non-linear quadratic programming problem, and inversion results are acquired under several constraints.

本文提出了一种基于非线性二次规划的叠前三参数反演方法。首先基于贝叶斯参数估计理论，假设似然函数服从高斯分布，并使待反演的参数服从于改进的Cauchy分布，从而提高了反演结果的分辨率；其次用协方差矩阵来描述参数间的相关程度，进一步提高了反演结果的稳定性；最后将问题转化为一个非线性二次规划的求解问题，并在多种约束下得到问题的解。

With the dose of 7.04 mC/cm2, ODT/Au will become a more strengthened structure and then form a negative resist in the correlation with cross-linking from alkyl matrix, partial breakdown of S-Au bonding and surface adsorption by air-borne species. Thus, it can obtain a gold pattern via gold-etching process. Besides, as a result of massive breakdown of alkyl matrix and S-Au bonding from ODT/Au under irradiation with doses of 64.06 and 128.13 mC/cm2, ODT SAMs would form a loose-packed structure on the gold substrate. The ODT/Au becomes less resistive for gold-etching and a positive gold pattern would form after gold-etching.

结果发现：以50 eV 低能量电子在照射剂量7.04 mC/cm2微影并曝露於大气后，受到来自於ODT/Au碳链间的交联、部分的S-Au键结破坏以及照射后立即曝露大气所吸附於表面的碳氧化物种的共同影响下，ODT SAMa於Au膜基材上将形成更紧密复杂的结构而作为负型阻剂，经后续湿式蚀刻15分钟后将显影出来Au的负型图案；当提升照射剂量至64.06及128.13 mC/cm2后，由於ODT/Au上碳链及S-Au键结的大量破坏，将使ODT/Au结构不能稳固且紧密地排列於Au膜基材上，显影时Au蚀刻液将容易穿过ODT SAMs抵达S/Au界面而移除Au，而形成正型图案。
