Abstract:
A method for manufacturing a semiconductor device, comprising:thermally growing a first insulating layer made of silicon oxide on a silicon substrate;forming a gate electrode on said first insulating layer;forming a second insulating layer on said gate electrode;forming a capacitor lower electrode on said second insulating layer;forming a capacitor dielectric layer on said capacitor lower electrode;forming a capacitor upper electrode on said capacitor dielectric layer;forming a third insulating layer on said capacitor dielectric layer;carrying out hydrogen passivation at a first temperature after said third insulating layer is formed;forming a first metal wiring layer on said third insulating layer after said hydrogen passivation is carried out;forming a fourth insulating layer on said it metal layer at a second temperature lower than said first temperature;forming a second metal wiring layer on said fourth insulating layer; andforming a passivation layer on said second metal layer at a third temperature lower than said first temperature.
