Toshiba and Sandisk will begin in september with the construction of a new facility for the production of 3d-nand flash. In 2016, the first chips of the belt reel and five years later, the modules of stacked memory has a capacity of 1TB.
Toshiba announces the current Fab 2 at its Yokkaichi site, which is used for the production of regular 2d nand, to be demolished to make way for a new facility that 3d nand should produce. The manufacturers were earlier planning to Fab 2 in order to build for the 3d-nandproductie and it this year to start. The new fab is together with Sandisk built. In the summer of 2015, the new factory is ready and during the transition from 2d – to 3d-nand is the cleanroom prepared. This should in 2016 be ready.
With the demolition and construction would be an amount of 700 billion yen, the euro 5 billion euros, and Toshiba and Sandisk, would each half of these costs. The new Fab to Toshiba and Sandisk corporation in a better competitive position against Samsung, SK Hynix and Micron. Samsung has already started with the production of 3d-nand flash, SK Hynix wants at the end of this year and Micron has recently introduced a dram factory converted to nand production.
Conventional nand memory is built from chips from a single layer of transistors exist. In a chip-package are often several chips opeengestapeld, but these are separate chips, while in 3d nand has multiple layers of transistors on a single chip are integrated. This stack brings significantly higher storage capacities. Nandflash, among others, in ssds, usb sticks and memory cards used. “Five years after the launch of the new factory, we want to 1TB-produce products,” says a spokeswoman from Toshiba at news agency AFP. It is unclear whether they are referring to individual chips, whose capacity is usually in bits is specified, or modules such as, for example, mmc. Even before the transition to 3d nand makes Toshiba the step of 19nm to 15nm-production. In June the mass production of this start, claims to EETimes, what the costs should decrease. The 15nm production is used for 128Gb chips.
