This is a very general question regarding planar CMOS Bulk production. As we all know that due to lots of problems in terms of Reliable Design in the presence of Power, Speed for CMOS bulk; the industry shifted in production of FDSOI and FinFETs. But I was wondering there is any company still producing ICs with CMOS Bulk below 30nm?
On the other hand you ll see many research publications on IEEE/ACM with BSIM predictive tech. models with 22nm and 16nm PTM - Latest models.
Thank you for your reply. I have tried to find out the datesheet or some kind of official documentation for A8 but unable to find. There is no where mention the word Bulk or Planar but only CMOS. Is it a convention? I am afraid if it may be of CMOS SOI? what do you suggest? any link for official documentation with proper info.
If you mean, FD-SOI, then no, 20nm is built on normal 300mm substrates with a planar technology (no FinFets).
About the naming convention, you can have a look at this doc: http://www.soitec.com/pdf/WP_handel-jones.pdf
Thank you for the white paper and for confirmation that Apple A8 is based on CMOS bulk (planar).
By the way, I have heard the rumor about STmicroelectronics; that they have also launched a 22nm node in bulk. Do anyone has any idea about it? any news or web-link will be appreciated.
STM has access to 20nm bulk planar that was developed with IBM/Samsung/GF (called 20LPM). However, I have not seen any product in the market that uses the said process. They are running their 28nm FDSOI and are im process of migrating to what they call 14FDSOI, which has GRs comparable to 20nm bulk planar, i.e. metal pitch of 64nm.
