    摘要: A method for forming a support structure for supporting and handling a semiconductor wafer containing vertical FETs formed at the front surface thereof is provided. In one embodiment, a semiconductor wafer is provided having a front surface and a rear surface, wherein the front surface comprises one or more dies separated by dicing lines. The wafer is thinned to a predetermined thickness. A plurality of patterned metal features are formed on a thinned rear surface to provide support for the wafer, wherein each of the plurality of patterned metal features covers substantially one die, leaving the dicing lines substantially uncovered. The wafer is thereafter diced along the dicing lines to separate the one or more dies for later chip packaging.

    摘要: An apparatus including a bypass structure for complementary metal-oxide-semiconductor (CMOS) and/or microelectromechanical system (MEMS) devices, and method for fabricating such apparatus, is disclosed. An exemplary apparatus includes a first substrate; a second substrate that includes a MEMS device; an insulator disposed between the first substrate and the second substrate; and an electrical bypass structure disposed in the insulator layer that contacts a portion of the first substrate, wherein the electrical bypass structure is electrically isolated from the MEMS device in the second substrate and any device included in the first substrate.
