  • Publication number: 20170012124
    Abstract: Techniques are disclosed for improved integration of germanium (Ge)-rich p-MOS source/drain contacts to, for example, reduce contact resistance. The techniques include depositing the p-type Ge-rich layer directly on a silicon (Si) surface in the contact trench location, because Si surfaces are favorable for deposition of high quality conductive Ge-rich materials. In one example method, the Ge-rich layer is deposited on a surface of the Si substrate in the source/drain contact trench locations, after removing a sacrificial silicon germanium (SiGe) layer previously deposited in the source/drain locations. In another example method, the Ge-rich layer is deposited on a Si cladding layer in the contact trench locations, where the Si cladding layer is deposited on a functional p-type SiGe layer. In some cases, the Ge-rich layer comprises at least 50% Ge (and may contain tin (Sn) and/or Si) and is boron (B) doped at levels above 1E20 cm?3.

  • Publication number: 20160351701
    Abstract: Techniques are disclosed for incorporating high mobility strained channels into fin-based NMOS transistors (e.g., FinFETs such as double-gate, trigate, etc), wherein a stress material is cladded onto the channel area of the fin. In one example embodiment, a germanium or silicon germanium film is cladded onto silicon fins in order to provide a desired tensile strain in the core of the fin, although other fin and cladding materials can be used. The techniques are compatible with typical process flows, and cladding deposition can occur at a plurality of locations within typical process flow. In various embodiments, fins may be formed with a minimum width (or later thinned) so as to improve transistor performance. In some embodiments, a thinned fin also increases tensile strain across the core of a cladded fin. In some cases, strain in the core may be further enhanced by adding an embedded silicon epitaxial source and drain.

  • Publication number: 20160328353
    Abstract: Several systems and methods of chip select are described. In one such method, a device maintains two identifiers, (ID_a and ID_m). When the device receives a command, it examines the values of ID_a and ID_m relative to a third reference identifier (ID_s). If either ID_a or ID_m is equivalent to ID_s, the device executes the command, otherwise, the device ignores the command. By using two different identification methods, a system has options in choosing to activate devices, being able to selectively switch between selecting multiple devices and single devices in a quick manner. In another such method, a device may have a persistent area that stores identification information such as an ID_a. Thus, system functionality may remain independent from any defect/marginality associated with the physical or logical components required for initial ID_a assignment of all devices in the system.

  • Publication number: 20160329431
    Abstract: Techniques are disclosed for forming transistor devices having reduced parasitic contact resistance relative to conventional devices. In some example embodiments, the techniques can be used to implement the contacts of MOS transistors of a CMOS device, where an intermediate III-V semiconductor material layer is provided between the p-type and n-type source/drain regions and their respective contact metals to significantly reduce contact resistance. The intermediate III-V semiconductor material layer may have a small bandgap (e.g., lower than 0.5 eV) and/or otherwise be doped to provide the desired conductivity. The techniques can be used on numerous transistor architectures (e.g., planar, finned, and nanowire transistors), including strained and unstrained channel structures.

  • Publication number: 20160322359
    Abstract: Techniques are disclosed for forming transistor devices having reduced parasitic contact resistance relative to conventional devices. The techniques can be implemented, for example, using a standard contact stack such as a series of metals on, for example, silicon or silicon germanium (SiGe) source/drain regions. In accordance with one example such embodiment, an intermediate boron doped germanium layer is provided between the source/drain and contact metals to significantly reduce contact resistance. Numerous transistor configurations and suitable fabrication processes will be apparent in light of this disclosure, including both planar and non-planar transistor structures (e.g., FinFETs), as well as strained and unstrained channel structures. Graded buffering can be used to reduce misfit dislocation. The techniques are particularly well-suited for implementing p-type devices, but can be used for n-type devices if so desired.

  • Publication number: 20160308032
    Abstract: Transistor fin elements (e.g., fin or tri gate) may be modified by radio frequency (RF) plasma and/or thermal processing for purpose of dimensional sculpting. The etched, thinned fins may be formed by first forming wider single crystal fins, and after depositing trench oxide material between the wider fins, etching the wider fins using a second etch to form narrower single crystal fins having undamaged top and sidewalls for epitaxially growing active channel material. The second etch may remove a thickness of between a 1 nm and 15 nm of the top surfaces and the sidewalls of the wider fins. It may remove the thickness using (1) chlorine or fluorine based chemistry using low ion energy plasma processing, or (2) low temperature thermal processing that does not damage fins via energetic ion bombardment, oxidation or by leaving behind etch residue that could disrupt the epitaxial growth quality of the second material.

  • Publication number: 20160293760
    Abstract: An n-MOS transistor device and method for forming such a device are disclosed. The n-MOS transistor device comprises a semiconductor substrate with one or more replacement active regions formed above the substrate. The replacement active regions comprise a first III-V semiconductor material. A gate structure is formed above the replacement active regions. Source/Drain (S/D) recesses are formed in the replacement active region adjacent to the gate structure. Replacement S/D regions are formed in the S/D recesses and comprise a second III-V semiconductor material having a lattice constant that is smaller than the lattice constant of the first III-V semiconductor material. The smaller lattice constant of the second III-V material induces a uniaxial-strain on the channel formed from the first III-V material. The uniaxial strain in the channel improves carrier mobility in the n-MOS device.
