摘要: Embodiments of the present disclosure provide techniques and configurations associated with conversion of thin transistor elements from silicon (Si) to silicon germanium (SiGe). In one embodiment, a method includes providing a semiconductor substrate having a channel body of a transistor device disposed on the semiconductor substrate, the channel body comprising silicon, forming a cladding layer comprising germanium on the channel body, and annealing the channel body to cause the germanium to diffuse into the channel body. Other embodiments may be described and/or claimed.

摘要: Techniques are disclosed for customization of fin-based transistor devices to provide a diverse range of channel configurations and/or material systems within the same integrated circuit die. In accordance with one example embodiment, sacrificial fins are removed and replaced with custom semiconductor material of arbitrary composition and strain suitable for a given application. In one such case, each of a first set of the sacrificial fins is recessed or otherwise removed and replaced with a p-type material, and each of a second set of the sacrificial fins is recessed or otherwise removed and replaced with an n-type material. The p-type material can be completely independent of the process for the n-type material, and vice-versa. Numerous other circuit configurations and device variations are enabled using the techniques provided herein.
