    摘要: A semiconductor device includes a substrate extending in a first direction to define a substrate length and a second direction perpendicular to the first direction to define a substrate width. A first semiconductor fin is formed on an upper surface of the substrate. The first semiconductor fin extends along the second direction at a first distance to define a first fin width. A first gate channel is formed between a first source/drain junction formed in the substrate and a second source/drain junction formed in the first semiconductor fin. A first gate stack is formed on sidewalls of the first gate channel. A first spacer is interposed between the first gate stack and the first source/drain junction.

    摘要: A transistor device and a method for forming a fin-shaped field effect transistor (FinFET) device, with the channel portion of the fins on buried silicon oxide, while the source and drain portions of the fins on silicon. An example method includes receiving a wafer with a silicon layer electrically isolated from a silicon substrate by a buried oxide (BOX) layer. The BOX layer is in physical contact with the silicon layer and the silicon substrate. The method further comprises implanting a well in the silicon substrate and forming vertical sources and drains over the well between dummy gates. The vertical sources and drains extend through the BOX layer, fins, and a portion of the dummy gates.

    摘要: A FinFET structure is formed by forming a hardmask layer on a substrate including a silicon-containing layer on an insulating layer. The hardmask layer includes first, second and third layers on the silicon-containing layer. An array of fins is formed from the hardmask layer and the silicon-containing layer. A gate is formed covering a portion but not all of a length of each of the array of fins. The portion covers each of the fins in the array. The gate defines source/drain regions on either side of the gate. A spacer is formed on each side of the gate, the forming of the spacer performed to remove the third layer from portions of the fins in the source/drain regions. The second layer of the hardmask layer is removed from the portions of the fins in the source/drain regions, and the fins in the source/drain regions are merged.

    摘要: A semiconductor material layer is deposited on a p-type source/drain region of a p-type transistor device and an n-type source/drain region of an n-type transistor device. The p-type device transistor device and the n-type transistor device are formed on a substrate of a semiconductor device. The semiconductor device includes a trench formed through an inter-level dielectric layer. The inter-level dielectric layer is formed over the n-type transistor device and the p-type transistor device. The trench exposes the p-type source/drain region of the p-type transistor device and the n-type source/drain region of the n-type transistor device. An element is implanted in the semiconductor material layer to form an amorphous layer on p-type source drain region and the n-type source/drain region. The amorphous layer is annealed to form a first metastable alloy layer upon the p-type source/drain region and a second metastable alloy layer upon the n-type source/drain region.
