An IC structure includes an MFMIS memory cell on a semiconductor substrate, and a CMOS transistor adjacent the MFMIS memory cell on the same semiconductor substrate. A method provides co-integration of the MFMIS memory cell with the CMOS transistor. The method may optionally co-integrate an MFIS memory cell. The IC structure and method provide a lower cost approach to forming MFMIS memory cells, which provide a number of advantages over MFIS memory cells.

Structures for a field-effect transistor and methods of forming a structure for a field-effect transistor. The structure comprises a silicon-on-insulator substrate including a semiconductor substrate, a dielectric layer on the semiconductor substrate, and a semiconductor layer on the dielectric layer. The structure further comprises a gate electrode on the semiconductor layer. The gate electrode comprises a single-crystal semiconductor material. The structure further comprises a spacer structure including a first portion that overlaps with a side surface of the dielectric layer and a second portion that overlaps with a portion of the semiconductor substrate adjacent to the side surface of the dielectric layer.

The present disclosure relates to semiconductor structures and, more particularly, to a layout optimization for radio frequency (RF) device performance and methods of manufacture. The structure includes: a first active device on a substrate; source and drain diffusion regions adjacent to the first active device; and a first contact in electrical contact with the source and drain diffusion regions and which is spaced away from the first active device to optimize a stress component in a channel region of the first active device.

Stress layout optimization for device performance

Structures including a ferroelectric field-effect transistor and methods of forming a structure including a ferroelectric field-effect transistor. The structure comprises a semiconductor substrate, a semiconductor layer, a dielectric layer arranged between the semiconductor layer and the semiconductor substrate, and first and second wells in the semiconductor substrate. The first well has a first conductivity type, and the second well has a second conductivity type opposite to the first conductivity type. A ferroelectric field-effect transistor comprises a gate structure on the semiconductor layer over the first well and the second well. The gate structure includes a ferroelectric layer comprising a ferroelectric material.

Disclosed is a reconfigurable complementary metal oxide semiconductor (CMOS) device with multiple operating modes (e.g., frequency multiplication mode, etc.). The device includes an N-type field effect transistor (NFET) and a P-type field effect transistor (PFET), which are threshold voltage-programmable, which are connected in parallel, and which have electrically connected gates. The threshold voltages of the NFET and PFET can be concurrently programmed and the operating mode of the device can be set depending upon the specific combination of threshold voltages achieved in the NFET and PFET. Optionally, the threshold voltages of the NFET and PFET can be concurrently reprogrammed to switch the operating mode. Such a device is relatively small and achieves frequency multiplication and other functions with minimal power consumption. Also disclosed are methods for forming the device and for reconfiguring the device (i.e., for concurrently programming the NFET and PFET to set or switch operating modes).
