Stacked Die Packaging technology is the key technique to meet the requirements of higher density, smaller size of electronic products. Moisture has big influence on the reliability of packaging, in which the major failures are corrosion, delamination and crack. In stacked die packages,the main risks of the moisture also exist. The focus of this paper is to investigate the hygroscopic characteristc of stacked die using commercial FEA software. In this study,according to the JEDEC standard, the moisture diffusion characteristic under different conditions is *** show that the substrate and bottom adhesive absorb rapidly in moisture diffusion simulation. This reduces the mechanical properties of the stacked die and the result may give a proper answer to those failure observed in *** tests are needed in order to get a more precise investigation.

In modern information society, the display devices play an important role. Presently, Organic Light-Emitting Diode (OLED) has been emphasized and regarded as one of the best technology for its many advantages, such as active-matrix driver mode, high brightness, fast response time, high efficiency, wide visual angle, thin and light-weight etc. Much work of this paper has been done in AM-OLED technology, mainly focusing on the models of AM-OLED pixel circuit structure design and parameters assurance, AC-driving pixel circuit design and application. This research is prepared for integrated peripheral driving circuit design and application in the future.

An efficient depth image based rendering (DIBR) for generating arbitrary novel views is proposed. The proposed method fills the holes by preprocessing depth images and merging two desired images. In order to solve the visibility problem, the pixels in reference image are processed in an occlusion-compatible order. Furthermore, the reference images are corrected before 3D image warping so as to reduce the edge artifacts. Experimental results have show that the proposed method can provide a satisfactory image quality.

Generating accurate geometric model of a real world environment and improving the rendering quality remained as the bottleneck problems in the field of arbitrary-view rendering. Inspired by the geometrical limitations between input images, we applied a fast image-based rendering (IBR) method for interactively synthesizing arbitrary-view. Although images form different views are needed, only "Region of Interest" (ROI) is used for the synthesis. Besides, a depth correction scheme based on plane-sweep algorithm was used to diminish visual artifact caused by insufficient geometric information. The good performance of our prototyped system has demonstrated the validity and potential of the proposed method.
