Abstract: A novel anti-inflammatory compound has the general formula (I): wherein the R1, R2 and R3 are same or different, and independently selected from a group consisting of H, halo, alkyl, alkenyl, alkynyl, cyclyl, heterocyclyl, alkoxyl, aryl, heteroaryl, alkylaryl and CF3. An anti-inflammatory composition includes the compound of general formula (I) or the salt, ester and/or hydrate thereof. The anti-inflammatory compound may be separated from a fruit extract, such as pineapple extract, and exhibits inhibitory effects on stimulated inflammatory response.

Abstract: Methods for fabricating multiple inverter structures in a multi-layer semiconductor structure are provided. A first device layer is formed on a substrate. The first device layer comprises one or more first inverter structures including a first input terminal and a first output terminal. A second device layer is formed on the first device layer. The second device layer comprises one or more second inverter structures including a second input terminal and a second output terminal. One or more inter-layer connection structures are formed. The one or more inter-layer connection structures are disposed to electrically connect the first input terminal to the second output terminal and electrically connect the first output terminal to the second input terminal.

Abstract: A method comprises: selecting a circuit pattern or network of circuit patterns in a layout of an integrated circuit (IC) to be fabricating using double patterning technology (DPT). Circuit patterns near the selected circuit pattern or network are grouped into one or more groups. For each group, a respective expected resistance-capacitance (RC) extraction error cost is calculated, which is associated with a mask alignment error, for two different sets of mask assignments. The circuit patterns in the one or more groups are assigned to be patterned by respective photomasks, so as to minimize a total of the expected RC extraction error costs.
