Summary
TSMC deep trench capacitor (DTC)
1500nF/mm2 is demonstrated for 1.2V operation voltage.
TCC and VCC are superior to commercial capacitors.
Equivalent series resistance and inductance
Capacitor with in-parallel DTC cells can provide excellent
ESR and ESL.
Surface mount capacitor
Low ESR and ESL can be achieved by interconnection
optimization.
DTC process offers thin IPD thickness (<70um).
