Compact fluid analysis device and method to fabricate

The present disclosure relates to a device for analyzing a fluid sample. In one aspect, the device includes a fluidic substrate that comprises a micro-fluidic component embedded in the fluidic substrate configured to propagate a fluid sample via capillary force through the device and a means for providing a fluid sample connected to the micro-fluidic component. The device also includes a lid attached to the fluidic substrate at least partly covering the fluidic substrate and at least partly closing the micro-fluidic component. The fluidic substrate may be a silicon fluidic substrate and the lid may be a CMOS chip. In another aspect, embodiments of the present disclosure relate to a method for fabricating such a device, and the method may include providing a fluidic substrate, providing a lid, and attaching, through a CMOS compatible bonding process, the fluidic substrate to the lid to close the fluidic substrate at least partly.
