摘要:
A method of forming an integrated circuit structure includes providing a gate strip in an inter-layer dielectric (ILD) layer. The gate strip comprises a metal gate electrode over a high-k gate dielectric. An electrical transmission structure is formed over the gate strip and a conductive strip is formed over the electrical transmission structure. The conductive strip has a width greater than a width of the gate strip. A contact plug is formed above the conductive strip and surrounded by an additional ILD layer.

A method for planarizing integrated circuit topographies, wherein, after a first layer of spin-on glass is deposited, a layer of low-temperature oxide is deposited before a second layer of spin-on glass.
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.

The mechanisms of forming SiC crystalline regions on Si substrate described above enable formation and integration of GaN-based devices and Si-based devices on a same substrate. The SiC crystalline regions are formed by implanting carbon into regions of Si substrate and then annealing the substrate. An implant-stop layer is used to cover the Si device regions during formation of the SiC crystalline regions.
