    摘要: Cap layers (144) are formed on silicon germanium (SiGe) source/drain regions (140) of field-effect transistors, in particular FinFETs and GAA-FETs, to provide etch resistance to processing steps that can occur in a semiconductor manufacturing process between formation of the SiGe source/drain regions and metal contact (152) formation. The cap layers (144) comprise boron and are thin (e.g., 2 nm or less) to provide for a low metal contact resistance. The atomic concentration of boron in the cap layer is in a range of about 0.2-20%, and the cap layer preferably further comprises Si and Ge. In addition to providing etch resistance, the cap layer provides for a thermally stable contact resistance as the cap layer can prevent or limit the creation of voids in the SiGe layer by preventing or limiting the diffusion of germanium from the SiGe layer into the metal (148, 152) in subsequent annealing and other high-temperature processing steps.As metal-silicon-germanium region (168) is preferably formed between the source/drain region (140) and the metal contact (152).

    摘要: An integrated circuit structure includes a first non-planar semiconductor device (101) and a second non-planar semiconductor device (151). The first non-planar semiconductor device includes a first body (118a, 118b, 118c), a first gate structure (132, 120) at least in part wrapped around the first body, and a first source region and a first drain region. The first body extends laterally between the first source and first drain regions. The second non-planar semiconductor device comprises a second body (168a, 168b, 168c), a second gate structure (170, 182) at least in part wrapped around the second body, and a second source region and a second drain region. The second body extends laterally between the second source and second drain regions. In an example, a first height (hL) of the first body is at least 5% different from a second height (hH) of the second body. Each of the first and second bodies can be, for instance, a nanoribbon, nanosheet, or nanowire.

    摘要: Techniques are disclosed for wafer bonding with an encapsulation layer. A first semiconductor substrate is provided. An encapsulation layer is then formed on top of the first semiconductor substrate. The encapsulation layer is formed of an encapsulation material that creates a stable oxide when exposed to an oxidizing agent. A first bonding layer is formed on top of the encapsulation layer. Next, a second semiconductor substrate is provided. A second bonding layer is formed on top of the second bonding layer. Thereafter, the first semiconductor substrate is bonded to the second semiconductor substrate by attaching the first bonding layer to the second bonding layer.
