A split-gate (SG) flash memory cell has been embedded in a 65nm ground-rule high performance (HP) CMOS logic process with copper low K interconnects. A gate spacer processing sequence self-aligned (SA) process provides a reliability-robust cell and high degree of modularity with one extra mask to form the SG structure. The proposed cell is optimized for minimum module area overhead, high endurance...
Reaction of 2,3-dichloro-5,6-dicyano-benzoquinone (DDQ) with secondary enaminones yields surprisingly 2-aza-spiro[4,5]decatrienes. The reaction occurs via cyclisation of the primary Michael-adduct with the nitrile group. Reaction of DDQ with tertiary and also certain secondary enamines leads to 3-amino-benzo[b]furan derivatives. This is formed not by Michael-addition, but via geminate radical ion...
