摘要： Disclosed is semiconductor structure with an insulator layer on a semiconductor substrate and a device layer is on the insulator layer. The substrate is doped with a relatively low dose of a dopant having a given conductivity type such that it has a relatively high resistivity. Additionally, a portion of the semiconductor substrate immediately adjacent to the insulator layer can be doped with a slightly higher dose of the same dopant, a different dopant having the same conductivity type or a combination thereof. Optionally, micro-cavities are created within this same portion so as to balance out any increase in conductivity due to increased doping with a corresponding increase in resistivity. Increasing the dopant concentration at the semiconductor substrate-insulator layer interface raises the threshold voltage (Vt) of any resulting parasitic capacitors and, thereby reduces harmonic behavior. Also disclosed herein are embodiments of a method for forming such a semiconductor structure.
摘要翻译：公开了在半导体衬底上具有绝缘体层并且器件层位于绝缘体层上的半导体结构。衬底掺杂有相对低剂量的具有给定导电类型的掺杂剂，使得其具有相对高的电阻率。此外，与绝缘体层紧密相邻的半导体衬底的一部分可掺杂略高的相同掺杂剂剂量，具有相同导电类型的不同掺杂剂或其组合。可选地，在该相同部分内形成微腔，以便平衡由于掺杂增加导致的电导率的增加，同时具有相应的电阻率增加。增加半导体衬底 - 绝缘体层界面处的掺杂剂浓度会提高任何结果的寄生电容器的阈值电压（Vt），从而降低谐波行为。本文还公开了用于形成这种半导体结构的方法的实施例。

摘要： A doped contact region having an opposite conductivity type as a bottom semiconductor layer is provided underneath a buried insulator layer in a bottom semiconductor layer. At least one conductive via structure extends from an interconnect-level metal line through a middle-of-line (MOL) dielectric layer, a shallow trench isolation structure in a top semiconductor layer, and a buried insulator layer and to the doped contact region. The doped contact region is biased at a voltage that is at or close to a peak voltage in the RF switch that removes minority charge carriers within the induced charge layer. The minority charge carriers are drained through the doped contact region and the at least one conductive via structure. Rapid discharge of mobile electrical charges in the induce charge layer reduces harmonic generation and signal distortion in the RF switch. A design structure for the semiconductor structure is also provided.

摘要： At least one conductive via structure is formed from an interconnect-level metal line through a middle-of-line (MOL) dielectric layer, a shallow trench isolation structure in a top semiconductor layer, and a buried insulator layer to a bottom semiconductor layer. The shallow trench isolation structure laterally abuts at least two field effect transistors that function as a radio frequency (RF) switch. The at least one conductive via structure and the at interconnect-level metal line may provide a low resistance electrical path from the induced charge layer in a bottom semiconductor layer to electrical ground, discharging the electrical charge in the induced charge layer. The discharge of the charge in the induced charge layer thus reduces capacitive coupling between the semiconductor devices and the bottom semiconductor layer, and thus secondary coupling between components electrically disconnected by the RF switch is reduced.
