Abstract: A nano-emulsion composition having a small particle size and ultra-low concentration and a preparation method thereof is disclosed. The raw materials of the composition comprise, in terms of percentage by weight, 0.002% to 0.2% of a polymer-containing homogeneous microemulsion, water, and 99.998% to 99.8% of an organic salt solution or inorganic salt solution. The composition is prepared by diluting a polymer-containing homogeneous microemulsion with water or a salt solution. The polymer-containing homogeneous microemulsion is formed by mixing the following raw materials, in terms of percentage by weight: 8% to 40% of a surfactant, 0.5% to 10% of a polymer, 10% to 30% of an alcohol, 3% to 30% of an oil, 0% to 20% of a salt, and balance of water. The composition of the invention is low in concentration, low in cost, narrow in particle size distribution, good in stability, simple in preparation, and convenient for storage and use.

Abstract: A computer implemented system and method is provided for generating a layout of the cell defining a circuit component, the layout providing a layout pattern for a target process technology. The method comprises obtaining an archetype layout providing a valid layout pattern for the cell having regard to design rules of the target process technology, and receiving an input data file providing a process technology independent schematic of the circuit component for which the cell is to be generated. A schematic sizing operation is then performed on the input data file, having regard to both schematic constraints applicable to the target process technology and layout constraints derived from the archetype layout, in order to generate an output data file providing a process technology dependent schematic of the circuit component. A cell generation operation is then performed using the output data file and layout data determined from the archetype layout in order to generate the layout of the cell.
