A method. A combination is provided of a block copolymer and additional material. The copolymer includes a first block of a first polymer covalently bonded to a second block of a second polymer. The additional material is miscible with the first polymer. The first polymer includes polystyrene and the second polymer includes poly(ethylene oxide). A first layer including polydimethylglutarimide is adhered onto a surface of a substrate including a dielectric coated silicon wafer. A film is formed of the combination directly onto a surface of the first layer. Nanostructures of the additional material self-assemble within the first polymer block. The film and the first layer are simultaneously etched. The nanostructures have an etch rate lower than an etch rate of the block copolymer and lower than an etch rate of the first layer. Portions of the film are removed. Features remain on the surface of the first layer.

Disclosed is a method of bias adjustment for a millimeter wave radar apparatus that can efficiently and highly accurately adjust the bias of an MMIC used in a radio frequency circuit in the millimeter wave radar apparatus. The method comprises: providing a DA converter in a bias circuit in the millimeter wave radar apparatus comprising an antenna, a radio frequency unit, and a processing unit for performing transmission and reception processing of the radio frequency unit; connecting a signal generator in place of the antenna; and connecting a test processing unit and a control apparatus to the radio frequency unit, wherein the control apparatus applies an initial bias value in the form of a digital value to the MMIC, calculates the target value for the digital bias value based on the result of the measurement of the received signal, and takes the target value as the digital bias value for the production processing unit when the radio frequency characteristic of the received signal obtained by applying the target value to the MMIC lies within specified limits.
