32nm Technology and 45nm Technology are the terms used in Semiconductor manufacturing. nm means nanometer. Big Giants like Intel, AMD uses these technology in building Processors. Both are used in the processors. Knowing the Difference between 32nm Technology and 45nm Technology will definitely help understand their role in the Processors. Below you will learn the differences between them.

32nm Technology

1. 32 nm Technology – Flash patterning capability based on double patterning and immersion lithography was first demonstrated in October 2006.
2. 32 nm refers to the expected average half-pitch of a memory cell at this technology level.
3. Intel demonstrated 32 nm processor in February 10, 2009 and started selling it on January 7, 2010 as Core i3, Core i5 and Dual Core mobile i7 processors.
4. 32nm Technology is the successor of 45nm Technology.
5. 32 nanometer process for logic, which uses significantly looser design rules.
6. Successor of 32nm Technology will be 22nm Technology and 16nm Technology.

45nm Technology

1. 45 nm Technology – Flash patterning capability based on double patterning and immersion lithography was first demonstrated in October 2006.
2. 45 nm refers to the expected average half-pitch of a memory cell at this technology level.
3. Matsushita and Intel started using 45 nm chips in late 2007, where as AMD started production in 2008. Intel’s Core i7 and Core i3 processors uses 45nm Technology.
4. 45nm Technology is the successor of 65nm Technology.
5. 45 nanometer process for logic, which uses significantly looser design rules.
6. Successor of 45nm Technology is 32nm Technology.
