The present invention relates to TNFR2-IL21R fusion protein acting as a double-antagonist to TNF-alpha (α) and IL-21. The composition containing the double antagonist to TNF-α and Il-21 (TNFR2-IL21R fusion protein), known as major causes of autoimmune rheumatoid arthritis, one of autoimmune diseases, can reduce the secretion of inflammatory cytokine, increase the secretion of anti-inflammatory cytokine, and suppress the differentiation of osteoclasts better than single proteins such as TNFR2-Fc and IL21R-Fc. The TNFR2-IL21R fusion protein of the present invention has not only excellent treatment effect on arthritis in CIA mouse model not also excellent treatment effect on autoimmune rheumatoid arthritis by increasing the expression of Treg, the immune suppressive cells. Therefore, the TNFR2-IL21R fusion protein of the present invention can be effectively used as an active ingredient for the composition for the prevention and treatment of autoimmune disease.

The present invention provides a flash memory device having a high degree of integration and high performance. The flash memory device has a double/triple gate structure where a channel is formed in a wall-shaped body. The flash memory device has no source/drain regions. In addition, although the flash memory device has the source/drain regions, the source/drain region are formed not to be overlapped with a control electrode. Accordingly, an inversion layer is induced by a fringing field generated from the control electrode, so that cell devices can be electrically connected to each other. The flash memory device includes a charge storage node for storing charges formed under the control electrode, so that miniaturization characteristics of cell device can be improved. According to the present invention, there is proposed a new device capable of improving the miniaturization characteristics of a MOS-based flash memory device and increasing memory capacity.

摘要:
Provided is a stacked chip package and a method for forming the same. A spacer is formed on a side of an upper chip. A conductive line is formed on the spacer to electrically connect upper and lower chips. The reliability of the stacked chip package is improved because wire bonding is not used to electrically connect the upper and lower chips. Further, the overall size of the stacked chip package can be reduced as the height of bonding wire loops does not contribute to the overall stacked chip package height.
