RIber reveals hybrid quantum platform
Riber has released details of a hybrid quantum platform designed to meet the demands of research groups working on qubits.
The company says the platform will drive significant improvements in material quality, growth control and transfer operations, paving the way for new developments in the emerging quantum field.
For the controlled growth of III-V heterostructures, MBE is the optimal technique. To enhance electron mobility, Riber integrates comprehensive equipment along with advanced real time in situ measurements via its EZ Instruments, which provide direct feedback to refine growth recipes as needed.
The platform also includes an independent hydrogen cleaning chamber, essential for the effective desorption of native oxides on the substrate. All chambers are directly connected to the cluster, enabling full automation of the process.
To separate the III-V process line, an additional cluster can be linked to the primary one, designed specifically for low-temperature superconductor growth and equipped with an oxidation chamber. There is a low-temperature chamber that enables the deposition of a thin layer of aluminium and other superconductors at a wafer temperature of 123K, with wafer rotation.
A quartz crystal microbalance enables precise growth monitoring, once calibrated, while wafer temperature is measured using Riber's EZ-Edge Band-edge thermometry instrument. Immediately following the aluminium evaporation, the aluminium surface undergoes oxidation to stabilised. The dedicated oxygen chamber, independently attached to the cluster, allows for a rapid, reproducible oxidation process, according to Riber.
Secure Your Hydrogen Supply
A study supply of high-purity hydrogen is critical to semiconductor fabrication. Supply chain interruptions are challenging manufacturers, leading to production slowdowns and stoppages. On-site hydrogen generation offers a scalable alternative for new and existing fabs, freeing the operator from dependence on delivered gas.Plant managers understand the critical role that hydrogen plays in semiconductor fabrication. That important job includes crystal growth, carrier gas, wafer annealing, and in the emerging Extreme UV Lithography (EUV) that will enable new generations of devices. As the vast need for semiconductors grows across all sectors of world economies, so does the need for high-purity hydrogen.
