摘要:
A semiconductor device and a method for manufacturing the device. The method includes: depositing a first dielectric layer on a semiconductor device; forming a plurality of first trenches through the first dielectric layer; depositing an insulating fill in the plurality of first trenches; planarizing the plurality of first trenches; forming a first gate contact between the plurality of first trenches; depositing a first contact fill in the first gate contact; planarizing the first gate contact; depositing a second dielectric layer on the device; forming a plurality of second trenches through the first and second dielectric layers; depositing a conductive fill in the plurality of second trenches; planarizing the plurality of second trenches; forming a second gate contact where the second gate contact is in contact with the first gate contact; depositing a second contact fill in the second gate contact; and planarizing the second gate contact.
