Abstract: Optimization of optical parametric models for structural analysis using optical critical dimension metrology is described. A method includes determining a first optical model fit for a parameter of a structure. The first optical model fit is based on a domain of quantities for a first model of the structure. A first near optical field response is determined for a first quantity of the domain of quantities and a second near optical field response is determined for a second, different quantity of the domain of quantities. The first and second near optical field responses are compared to locate a common region of high optical field intensity for the parameter of the structure. The first model of the structure is modified to provide a second, different model of the structure. A second, different optical model fit is determined for the parameter of the structure based on the second model of the structure.

Abstract: A semiconductor chip integrating a transceiver, an antenna, and a receiver is provided. The transceiver is located on a front side of a semiconductor substrate. A through substrate via provides electrical connection between the transceiver and the receiver located on a backside of the semiconductor substrate. The antenna connected to the transceiver is located in a dielectric layer located on the front side of the substrate. The separation between the reflector plate and the antenna is about the quarter wavelength of millimeter waves, which enhances radiation efficiency of the antenna. An array of through substrate dielectric vias may be employed to reduce the effective dielectric constant of the material between the antenna and the reflector plate, thereby reducing the wavelength of the millimeter wave and enhance the radiation efficiency. A design structure for designing, manufacturing, or testing a design for such a semiconductor chip is also provided.
