Abstract: Methods and materials for improving the hardness of a metallic photoresist used in EUV photolithography are disclosed. A metallic cross-linker is used with the metallic photoresist. The cross-linker comprises a metal core and a plurality of ligands. The ligands may comprise at least one vinyl group or at least one acetylene group; or comprise an acrylate; or comprise a cinnamate; or be unable to participate in a crosslinking reaction. Upon radiation exposure, the ligands separate from the metal core, and the metal core can crosslink, or the ligands may crosslink. The resulting photoresist layer has increased hardness and higher EUV light sensitivity, which permits a reduced radiation dosage.

Abstract: A centimeter-resolution integrated photonic millimeter-wave (mmWave) radar chip operating in the mmWave V band based on a 4-inch wafer-scale thin-film lithium niobate (TFLN) technology is provided. The fabricated TFLN photonic mmWave integrated circuit has a first electro-optic modulator (EOM) capable of generating a broadband linear frequency modulated mmWave radar waveform through optical frequency multiplication of a low-frequency input signal, and a second EOM for frequency de-chirp of the reflected echo wave, thereby greatly relieving bandwidth requirements for the digital-to-analog converter in the transmitter and analog-to-digital converter in the receiver. In the absence of optical and electrical filters, the radar chip features continuous on-demand tunability of the center frequency and bandwidth, currently only limited by the bandwidths of electrical amplifiers.
