Title: “From 2D to 3D memory: Moore’s law revisited”
Session: 09:30 - 10:00


Semiconductor technology has scaled at a tremendous pace in the past decades, leading to billions of transistors being integrated on one single silicon chip. DRAM chips are now available up to 8Gb densities, while Flash has even been outperforming with respect to the roadmap as dictated by Moore's law, ending up at 16nm dimensions yielding 128Gb on a single chip.
However, MOS transistors, DRAM and Flash memory cells are "charge based" which generates some particular scaling issues related to their electrostatics. In fact, in Flash memory these issues are so severe that the industry is currently transitioning from the classical scaling of lateral dimensions towards a stacking of memory layers on the same chip. Similar attempts in logic and DRAM technology are also being pursued in this exciting research area.
The talk will address these major scaling issues and illustrate how Moore's law has to be revisited when moving towards the 3rd dimension.


Jan Van Houdt received a MSc degree in Electrical and Mechanical Engineering and a PhD from the University of Leuven. During his PhD work, he invented the HIMOS™ Flash memory, which he transferred to several industrial production lines. In 1999 he became responsible for Flash memory at imec and as such was the driving force behind the expansion of imec's Memory Program. Today he is Chief Scientist in the Process Technology unit of imec. He has published more than 300 papers in international journals and accumulated more than 200 conference contributions (incl. 35 invitations and 5 best paper awards). He has filed more than 50 patents and served on the program and organizing committees of 10 major semiconductor conferences. In 2014 he received the title of IEEE Fellow for his contributions to Flash memory devices. Recently, he was appointed a part-time professor in Electrical Engineering and Nanotechnology at the University of Leuven.
