摘要: Methods of forming a strained channel device utilizing dislocations disposed in source/drain structures are described. Those methods and structures may include forming a thin silicon germanium material in a source/drain opening of a device comprising silicon, wherein multiple dislocations are formed in the silicon germanium material. A source/drain material may be formed on the thin silicon germanium material, wherein the dislocations induce a tensile strain in a channel region of the device.

摘要: An integrated circuit structure comprises a relaxed buffer stack that includes a channel region, wherein the relaxed buffer stack and the channel region include a group III-N semiconductor material, wherein the relaxed buffer stack comprises a plurality of AlGaN material layers and a buffer stack over the plurality of AlGaN material layers, wherein the buffer stack comprises the group III-N semiconductor material and has a thickness of less than approximately 25 nm. A back barrier is in the relaxed buffer stack between the plurality of AlGaN material layers and the buffer stack, wherein the back barrier comprises an AlGaN material of approximately 2-10% Al. A polarization stack over the relaxed buffer stack.

摘要: Embodiments herein describe techniques, systems, and method for a semiconductor device. Embodiments herein may present a semiconductor device having a channel area including a channel III-V material, and a source area including a first portion and a second portion of the source area. The first portion of the source area includes a first III-V material, and the second portion of the source area includes a second III-V material. The channel III-V material, the first III-V material and the second III-V material may have a same lattice constant. Moreover, the first III-V material has a first bandgap, and the second III-V material has a second bandgap, the channel III-V material has a channel III-V material bandgap, where the channel material bandgap, the second bandgap, and the first bandgap form a monotonic sequence of bandgaps. Other embodiments may be described and/or claimed.
