摘要:
An improved process for fabricating simultaneously high capacitance, less than 0.13 micron metal-insulator-metal capacitors, metal resistors and metal interconnects, has been developed using single or dual damascene processing. The key advantage is the use of only one additional mask reticle to form both MIM capacitor and resistor, simultaneously. Several current obstacles that exist in BEOL, back end of line, are overcome, namely: (a) the use of two or more photo-masks to make
