Buffer structures are provided that can be used to reduce a strain in a conformable electronic system that includes compliant components in electrical communication with more rigid device components. The buffer structures are disposed on, or at least partially embedded in, the conformable electronic system such that the buffer structures overlap with at least a portion of a junction region between a compliant component and a more rigid device component. The buffer structure can have a higher value of Young's modulus than an encapsulant of the conformable electronic system.

A metamaterial for deflecting an electromagnetic wave is disclosed, which comprises a functional layer. The functional layer comprises a plurality of sheet layers parallel to each other, and each of the sheet layers comprises a sheet-like substrate and a plurality of man-made microstructures arranged in an array on the sheet-like substrate. The sheet-like substrate comprises a plurality of unit blocks, and each of the man-made microstructures and a corresponding one of the unit blocks occupied thereby form a unit cell. Refractive indices of the unit cells arranged in a first direction in each of the sheet layers decrease gradually. Each of the unit cells has an anisotropic electromagnetic parameter. Through use of the metamaterial of the present disclosure, deflection of the electromagnetic wave can be achieved.

A method for manufacturing a multilayered circuit board, and a printed circuit board manufactured according to the method, includes laterally-aligning a first inner substrate in which first insulation layers and first conductor layers are alternately laminated and a second inner substrate in which second insulation layers and second conductor layers are alternately laminated. The second inner substrate has a lager number of layers than the first inner substrate. The laterally-aligned first inner substrate and second inner substrate are placed between a pair of third insulation layers in a thickness direction. The pair of the third insulation layer are heated under pressure in the thickness direction. A conductor pattern is formed on surfaces of the pair of the third insulation layers.

[Problem] To provide a reliable component-embedded module that allows a reduction in cost and an increase in yield. [Solving Means] A component-embedded module A includes a module substrate 1 having wiring electrodes 2 on the upper surface thereof, first circuit components 7 mounted on the wiring electrodes 2, a sub-module 10 disposed on an area on which no wiring electrodes 2 are formed, and an insulating resin layer 20 formed on the entire upper surface of the module substrate in such a manner that the insulating resin layer 20 covers at least parts of the first circuit components and sub-module. The second circuit components 15 including an integrated circuit element are mounted on the sub-module 10 or embedded therein. Via conductors 3 are formed through the module substrate 1 from the lower surface thereof and are directly coupled to terminal electrodes 14 on the lower surface of the sub-module 10. By using a substrate having a wiring accuracy higher than that of the module substrate 1, a reliable component-embedded module is obtained.
