III-V semiconductors such as GaAs, InGaAs, InP, InAs, GaN and others attract interest in microelectronics due to their high intrinsic electron mobility. Beneq Atomic Layer Deposition solutions can help extract the best electrical performance from these devices.
Radio frequency, or RF, devices operate on radio waves (20 kHz – 300 GHz) and can be split into two categories: integrated circuits (ICs) and filters. Although the two types differ greatly in their function, both encounter interfacial challenges which can impact their performance. For example unstable surface oxides, e.g. Ga2O3, make high quality passivation layers critical for the operation of RF ICs. RF filters can benefit from improved bonding strength and corrosion resistance on electrodes.
At Beneq, our Atomic Layer Deposition processes deposit ultra-thin and pinhole-free films with precision thickness control, high breakdown voltage and unparalleled step coverage. Our batch manufacturing cluster tools feature both thermal and plasma ALD, offering a range of thin film solutions for RF devices. Explore our solutions for RF ICs and filters below.
