Applied Materials Video Dramatizes 3D NAND Manufacture

Visualization of a column of ions etching a holeIn a little 3-minute video released this  week for the SEMICON West conference, Applied Materials dramatizes the 3D NAND manufacturing process by using hailstorms for atomic level deposition (ALD) and lightning bolts for etch, all while explaining that the wafer’s surface reaches temperatures hotter than the surface of the sun.

For those who already understand 3D NAND manufacture it’s an interesting Continue reading “Applied Materials Video Dramatizes 3D NAND Manufacture”

FRAM Turns 68

Photo of a memory chip next to a paper matchPerhaps the oldest nonvolatile semiconductor memory type is the ferroelectric memory, which recently celebrated its 68th birthday.  FRAM predates flash memory, EEPROM, and even UV-erasable EPROM.  It’s even older than mask ROM, which wasn’t invented until 1967!

As a matter of introduction to the technology, FRAM, or ferroelectric memory, is a read/write nonvolatile memory technology that performs significantly better than Continue reading “FRAM Turns 68”
