AbstractAbstract
[en] Polysaccharides widely used in the food industry were studied in terms of sterilization of bacteria by irradiation. 12 items of polysaccharides irradiated by electron beam ware investigated for bacteria count and the functional property of pH, gel strength, bloom and viscosity. This study aims to determine the sterilization effect by absorption dose and the applicability of the electron beam irradiation toward polysaccharides. Results shows that 1) Over 5kGy absorption dose are enough to be able to sterilize bacteria in the polysaccharide themselves. 2) We reconfirm that Arabic gum will be applicable for the electron beam irradiation, which has been used in some foreign countries. 3) Electron beam irradiation will be useful for Gellan gum b (acetyl type), as gelling agents in the food application.

AbstractAbstract
[en] We developed a vacuum underfill technology for 3D chip stacks and for flip chips in high performance system integration. We fabricated a 3D prototype chip stack using the vacuum underfill technology to apply the adhesive. The underfill was injected into each 6 µm gaps in a 3-layer chip stack and no voids were detected in acoustic microscopy images. Electrical tests and thermal reliability tests were used to measure the resistance of the vertical interconnections and the impact of the underfill. The results showed there was minimal difference in the average interconnection resistance of the chip stack with and without underfill.
