    Abstract: Systems and methods are provided for fabricating a semiconductor device structure. An example semiconductor device structure includes a first device layer, a second device layer and an inter-level connection structure. The first device layer includes a first conductive layer and a first dielectric layer formed on the first conductive layer, the first device layer being formed on a substrate. The second device layer includes a second conductive layer, the second device layer being formed on the first device layer. The inter-level connection structure includes one or more conductive materials and configured to electrically connect to the first conductive layer and the second conductive layer, the inter-level connection structure penetrating at least part of the first dielectric layer. The first conductive layer is configured to electrically connect to a first electrode structure of a first semiconductor device within the first device layer.

    Abstract: A method includes forming a first gate above a semiconductor substrate, forming a hard mask on the first gate, and forming a contact etch stop layer (CESL) on the hard mask. No hard mask is removed between the step of forming the hard mask and the step of forming the CESL. The method further includes forming an interlayer dielectric (ILD) layer over the CESL, and performing one or more CMP processes to planarize the ILD layer, remove the CESL on the hard mask, and remove at least one portion of the hard mask.

    Abstract: A replacement channel and a method for forming the same in a semiconductor device are provided. A channel area is defined in a substrate which is a surface of a semiconductor wafer or a structure such as a fin formed over the wafer. Portions of the channel region are removed and are replaced with a replacement channel material formed by an epitaxial growth/deposition process to include a first dopant concentration level less than a first dopant concentration level. A subsequent doping operation or operations is then used to boost the average dopant concentration to a level greater than the first dopant concentration level. The replacement channel material is formed to include a gradient in which the upper portion of the replacement channel material has a greater dopant concentration than the lower portion of replacement channel material.

    Abstract: The present disclosure relates to a semiconductor device including a substrate having a top surface and a gate stack. The gate stack includes a gate dielectric layer on the substrate and a gate electrode on the gate dielectric layer. The semiconductor device also includes a multi-spacer structure. The multi-spacer includes a first spacer formed on a sidewall of the gate stack, a second spacer, and a third spacer. The second spacer includes a first portion formed on a sidewall of the first spacer and a second portion formed on the top surface of the substrate. The second portion of the second spacer has a thickness in a first direction that gradually decreases. The third spacer is formed on the second portion of the second spacer and on the top surface of the substrate. The semiconductor device further includes a source/drain region formed in the substrate, and a portion of the third spacer abuts the source/drain region and the second portion of the second spacer.
