NIST finds La Luce Cristallina builds 100x thicker STO wafers for quantum devices

La Luce Cristallina has launched a 0.5-micrometer silicon-based quantum paraelectric strontium titanate on insulator wafer platform, offering a new foundation for quantum device research. The wafers feature a strontium titanate layer 100 times thicker than conventional designs, enabling the use of the material’s dielectric behavior at cryogenic temperatures. At these temperatures, strontium titanate enters a quantum paraelectric state, enhancing its responsiveness to electric fields and supporting applications like parametric amplifiers for qubit readout, La Luce Cristallina says. “Our new strontium titanate wafer provides a highly tunable materials platform for researchers developing quantum and cryogenic devices,” said Alex Demkov, CEO of La Luce Cristallina. QP-STOI Platform Enables 100x Thicker STO Wafers for Quantum Devices La Luce Cristallina now offers 0.5-micrometer wafers. The company built the layer to be 100 times thicker than conventional strontium titanate buffer layers typically used in epitaxial growth on silicon substrates. This increased thickness supports applications demanding precise electrical control, such as parametric amplifiers critical for qubit readout. At cryogenic temperatures, strontium titanate transitions into a quantum paraelectric state, dramatically increasing the responsiveness of its dielectric properties to electric fields. This tunability allows researchers to finely adjust electrical behavior, opening possibilities for tunable microwave components and future electro-optic devices. Beyond quantum applications, the platform’s piezoelectric properties also provide a foundation for electrically controlled actuators and precision sensors.

La Luce Cristallina emphasizes the platform’s compatibility with existing CMOS and foundry manufacturing processes, streamlining integration into established semiconductor workflows. Currently available in 2-inch wafers, the company anticipates scaling production to 200-millimeter wafers early next year. “By combining quantum paraelectric behavior with foundry-compatible manufacturing, we’re making it easier for researchers and device developers to explore new architectures for quantum sensing, qubit readout and related applications.” Our new strontium titanate wafer provides a highly tunable materials platform for researchers developing quantum and cryogenic devices, helping to support increased market interest in emerging use cases.
