This article details Intel's semiconductor process technology history for research and posterity.

Overview[edit]

The table below shows the history of Intel's process scaling. Values were taken from various Intel documents including IDF presentations, ISSCC papers, and IEDM papers. Note that while a great deal of effort was put into ensuring the accuracy of the values, some numbers vary to a small degree between Intel's own documents and therefore discrepancies may exist. SRAM bitcell areas refer to a high-density 6T bitcell with the exception of the very first few processes where smaller cell designs were used. Additionally, the metal layer count is for the client dies (example consumer mobile & desktop); server models utilize considerably more layers. Finally, from the 45 nm node, Intel has switched to utilizing a high-κ material, therefore the oxide thickness shown refers to the equivalent oxide thickness instead.

Nomenclature[edit]

Intel has been using the same naming scheme for decades. All process technologies (including packaging technologies) begin with a 'P' followed by the wafer size and the process ID. Generally, the process ID is an auto-increment value with odd values generally reserved for SoC and I/O (low power) devices while the even values have been used for Intel premier line of high-performance processors.

SRAM Scaling[edit]

For Intel, from 2 µm to 10 nm, SRAM 6T bit cells have had an average shrink of 0.496x in an attempt to maintain Moore's Law double density observation/requirement. Note that SRAM shrunk more significantly prior to the 65 nm process node. It should also be noted that logic typically scales better than the typical 6T SRAM cells, so raw logic density scaled more over time. Nonetheless, the size of the SRAM can be as much as three to four times the density of the typical logic cell.

-For Intel, from [[2 µm]] to [[10 nm]], SRAM 6T [[bit cells]] have had an average shrink of 0.496x in an attempt to maintain [[Moore's Law]] double density observation/requirement.
+For Intel, from [[2 µm]] to [[10 nm]], SRAM 6T [[bit cells]] have had an average shrink of 0.496x in an attempt to maintain [[Moore's Law]] double density observation/requirement. Note that SRAM shrunk more significantly prior to the [[65 nm process]] node. It should also be noted that logic typically scales better than the typical 6T SRAM cells, so raw logic density scaled more over time. Nonetheless, the size of the SRAM can be as much as three to four times the density of the typical logic cell.
