In 2020, due to the massive increase in global demand for smartphones, IoT applications, and high-performance computing devices. This demand has led the company to realize its best-ever quarterly financials and increased optimism in research opportunities.
Following a board meeting on February 9, to spend roughly $178 million on a Japanese subsidiary to expand its three-dimensional integrated circuit (3D IC) material research.

TSMC's Research Thus Far with 3D ICs and “3DFabric”
TSMC has been working with 3D-IC technology for quite some time. With computing applications and workloads are as demanding as they have ever been, TSMC claims it is leading the way into the third-dimension with This fabric is designed to complement its semiconductor IP.

At the , TSMC’s chairman Mark Liu spoke about 3D system fabrics as the key driver for keeping major technology developments and innovations moving. Liu also highlighted the future of 3D chip stacking with TSMC’s , in which a dozen dies can be stacked in a vertical space of less than 600 µm thanks to low-temperature bonding.

The $178 million USD in funding for TSMC’s Japanese R&D center will expand its efforts in 3D IC material development. Plans for the .
3D IC and SoIC
to behave as a single device. This method enables better performance metrics with reduced power consumption and a smaller footprint than two-dimensional circuits.
Improvements for 3D-IC technology may open doors to improvements in SoICs. These SoICs can integrate “chiplets” from different SoC parts and with varying functions into a new chip. TSMC also mentions its innovative bonding scheme that provides shorter and faster connections for those chiplets.
