摘要:
An improvement in the method of fabricating on chip decoupling capacitors which help prevent L di/dt voltage droop on the power grid for high surge current conditions is disclosed. The inclusion of a hybrid metal/metal nitride top electrode/barrier provides for a low cost and higher performance option to strapping decoupling capacitors.

PLC architectures and fabrication techniques for providing electrical and photonic integration of a photonic components with a semiconductor substrate. In the exemplary embodiment, the PLC is to accommodate optical input and/or output (I/O) as well as electrically couple to a microelectronic chip. One or more photonic chip or optical fiber terminal may be coupled to an optical I/O of the PLC. In embodiments the PLC includes a light modulator, photodetector and coupling regions supporting the optical I/O. Spin-on electro-optic polymer (EOP) may be utilized for the modulator while a photodefinable material is employed for a mode expander in the coupling region.

Photonic components are placed on the processor package to bring the optical signal close to the processor die. The processor package includes a substrate to which the processor die is coupled, and which allows the processor die to connect to a printed circuit board. The processor package also includes transceiver logic, electrical-optical conversion circuits, and an optical coupler. The electrical-optical conversion circuits can include laser(s), modulator(s), and photodetector(s) to transmit and receive and optical signal. The coupler interfaces to a fiber that extends off the processor package. Multiple fibers can be brought to the processor package allowing for a scalable high-speed, high-bandwidth interconnection to the processor.
摘要:
A metal-semiconductor-metal (MSM) device couples light from an optical mode in a waveguide to a surface plasmon polarition (SPP) mode on an electrode surface of the MSM device. Once in an SPP mode, the absorption of light in the semiconductor can take place in a very small area. This may allow for a shrinking of the active detector area and allow for low capacitance, very short transit distance for the electrical carriers and allow for very low voltage devices and/or very high frequency.

Embodiments of the present invention describe a waveguide-based photodetector device and its methods of fabrication. The waveguide photodetector device comprises a substrate having a cladding structure formed thereon. A waveguide element for receiving optical signals is disposed within the cladding structure. A portion of the waveguide element is encapsulated by a photodetector element that detects the optical signal received by the waveguide element and generates an electrical signal based on the optical signal. Encapsulating the waveguide element in the photodetector element improves coupling efficiency and enables a waveguide photodetector device with higher speeds and higher responsivity.
