Leti and CMP’s joint multi-project wafer service integrates silicon OxRAM
Available on Leti’s 200mm CMOS line, the MPW service provides a comprehensive, very low-cost way to explore techniques designed to achieve miniaturized, high-density components. Including Leti’s Memory Advanced Demonstrator (MAD) future mask set with disruptive OxRAM (oxide-based resistive RAM) technology, the integrated silicon memory platform is developed for backend memories and non-volatility associated with embedded designs. The new technology platform will be based on HfO2/Ti (titanium-doped hafnium oxide) active layers.
Emerging OxRAM non-volatile memory is one of the promising technologies to be implemented for classical embedded memory applications on advanced nodes like micro-controllers or secure products, as well as for AI accelerators and neuromorphic computing.
Leti’s MAD platform is dedicated to advanced non-volatile memories, bringing both versatility and robustness for material and interface assessment, and allowing in-depth exploration of memory performance from technology and design perspectives.
The full platform is based on 200mm STMicroelectronics HCMOS9A base wafers at the 130nm node, with all routing made on ST base wafers from M1 to M4 (included) and Leti’s OxRAM memory module fabricated on top. One level of interconnect (i.e. M5) plus pads are fabricated in Leti’s cleanroom.
The MPW service with integrated silicon OxRAM addresses all the key steps of advanced memory development. These include material engineering and analysis, developing critical memory modules, evaluation of memory cells coupled with electrical tests, modelling and innovative design techniques to comply with circuit design opportunities and constraints. This technology offer comes with a design kit, including layout, verification and simulation capabilities. Libraries are provided with a comprehensive list of active and passive electro-optical components. The design kit environment is compatible with all offers through CMP.
