Abstract: Ge and III-V channel semiconductor devices having maximized compliance and free surface relaxation and methods of fabricating such Ge and III-V channel semiconductor devices are described. For example, a semiconductor device includes a semiconductor fin disposed above a semiconductor substrate. The semiconductor fin has a central protruding or recessed segment spaced apart from a pair of protruding outer segments along a length of the semiconductor fin. A cladding layer region is disposed on the central protruding or recessed segment of the semiconductor fin. A gate stack is disposed on the cladding layer region. Source/drain regions are disposed in the pair of protruding outer segments of the semiconductor fin.

Abstract: Techniques are disclosed for forming integrated passive devices, such as inductors and capacitors, using next-generation lithography (NGL) processes, such as electron-beam direct write (EBDW) and extreme ultraviolet lithography (EUVL). The techniques can be used to form various different integrated passive devices, such as inductors (e.g., spiral inductors) and capacitors (e.g., metal finger capacitors), having higher density, precision, and quality factor (Q) values than if such devices were formed using 193 nm photolithography. The high Q and dense passive devices formed can be used in radio frequency (RF) and analog circuits to boost the performance of such circuits. The increased precision may be realized based on an improvement in, for example, line edge roughness (LER), achievable resolution/critical dimensions, sharpness of corners, and/or density of the formed structures.
