According to the national strategic plan and international nanotechnology developments in nanotechnology, with high density, high speed, low power consumption, reliable, and high performance phase change memory, high purity nano abrasive and polishing slurry as the main research directions, the team aims at developing PCRAM novel materials, chip design, process integration, testing technology and nano abrasive and CMP slurry with independent intellectual property rights, as well as setting up 8/12-inch PCRAM platform, developing a competitive PCRAM chip based on 130/110/40/28

nm design rule and establishing technical database for mass production, to realize the industrialization of independent intellectual PCRAM chip.

Major research focuses:

(1) PCRAM applied basic research: First principle calculation, development and engineering of novel PCRAM materials, 3D high-density switch and memory devices, and brain-like computing.

(2) Design, test and applications of PCRAM chip: 130/110/40/28 nm PCRAM circuit design, chip process design, independent test platform, 8/12 inch test platforms, packaging, testing and application of PCRAM chip.

(3) 8/12 inch PCRAM process development: Nano-filled, polished, etching and other process development; 1D, 1R, nano electrode, ring electrode process development; 1T1R, 1D1R process integration and optimization.

(4) High purity abrasive and CMP slurry: Nano abrasive with high purity, slurry for silicon polishing, sapphire polishing, and phase change material polishing slurry.
