Sub Wavelength

A thermopile device with sub-wavelength hole array (SHA) is numerically and experimentally investigated. The infrared absorbance (IRA) effect of SHAs in active area of the thermopile device is clearly analyzed by the finite-difference time-domain (FDTD) method. The prototypes are manufactured by the 0.35 μm 2P4M complementary metal-oxide-semiconductor micro-electro-mechanical-systems (CMOS-MEMS) process in Taiwan semiconductor manufacturing company (TSMC). The measurement results of those prototypes are similar to their simulation results. Based on the simulation technology, more sub-wavelength hole structural effects for IRA of such thermopile device are discussed. It is found from simulation results that the results of SHAs arranged in a hexagonal shape are significantly better than the results of SHAs arranged in a square and the infrared absorption efficiencies (IAEs) of specific asymmetric rectangle and elliptical hole structure arrays are higher than the relatively symmetric square and circular hole structure arrays. The overall best results are respectively up to 3.532 and 3.573 times higher than that without sub-wavelength structure at the target temperature of 60 °C when the minimum structure line width limit of the process is ignored. Obviously, the IRA can be enhanced when the SHAs are considered in active area of the thermopile device and the structural optimization of the SHAs is absolutely necessary.

Abstract An integrated mixing/reaction micro flow cell which consists of a sample/reagent mixing channel, a visible port and a reaction chamber was designed, fabricated and tested. A micro cone hole array of macro porous Si was employed for reagent injection part. A visible light transparent PDMS slab was used as the visible port. A Ti-Pt thin film heater and a p-n junction diode temperature sensor were integrated on the reaction chamber to realize feedback temperature control. Uniform mixing and precise temperature control were realized by the fabricated micro flow cell. The striate and simple microchannel structure of the micro flow cell is suitable for multiplexed micro reactor for chemical and biochemical applications.

The method of coordinate referencing of remote sensing materials in the process of satellite surveying is proposed in this paper. The method provides automatic determination of position of the survey routes and images in the routes on the surface of the Earth ellipsoid with their subsequent displaying on the nomenclature sheets of topographic maps on the composite table. The method provides for fully automatic development of a scheme of areal coverage with survey materials in the presence of data on the coordinates of photographing points obtained at the moments of exposure. The algorithm can be used to link images to the corresponding areas of electronic and digital maps.
