ELASTICALLY DEFORMABLE INTEGRATED-CIRCUIT DEVICE

摘要

The present invention relates to an integrated-circuit device comprising a multitude of separate rigid substrate islands (202 to 208) with circuit elements, a respective substrate island being connected to respective neighbor substrate islands by respective elastically deformable connections 210 to 222), which contain at least one respective signaling layer that is made of an electrically conductive material. At least one elastically deformable connection between substrate islands has a signaling layer, which is not electrically connected and thus forms a dummy signaling layer (210a to 210c), and the elastically deformable connections, which connect a respective substrate island to respective neighbor substrate islands along a first direction, have an elastic deformability in the first direction governed by respective moduli of elasticity, the ratio of which is between 0.5 and 2.0. This reduces the inhomogeneity of strain in the network of substrate islands that is formed by the integrated-circuit device. The functional reliability of the integrated-circuit device of the invention is increased over prior-art devices without restricting the freedom of circuit design.
