Abstract:
A low-k dielectric layer, such as SiCOH, with high and stable chemical mechanical polishing (CMP) removal rate (RR) is disclosed. The polishing rate enhancer (PRE) is disposed on the low-k dielectric layer. The PRE increases the CMP RR during CMP. Furthermore, the PRE stabilizes the increases CMP RR. This is particularly useful, for example, for memory applications in which the storage unit is formed in a low-k back-end-of-line (BEOL) dielectric layer. For example, the topography created can be quickly planarized by CMP while producing a uniform polished surface of the low-k dielectric layer due to the shortened processing time.

Claim (Index 5):
The device of  claim 1  wherein the plurality of ILD levels comprises:\n x ILD levels, wherein each ILD layer includes\n a contact level V i\u22121  where i is the i th  ILD level of the x ILD levels, and \n a metal level M i  where i is the i th  ILD level of the x ILD levels disposed over the contact level; and \n \n wherein the two adjacent metal levels of the BEOL dielectric layer between which the storage unit is disposed comprises\n an upper metal level M j , which is a j th  level of the x ILD levels, and \n a lower metal level M j-1 .
