Patent ID: 6960365

Claim:
A method of fabricating a vertical metal-insulator-metal capacitor (MIMCap), comprising: providing a workpiece; depositing an inter-level dielectric over the workpiece; patterning the inter-level dielectric to form a plurality of trenches having substantially vertical sidewalls and equal height and width dimensions; defining a first region of said inter-level dielectric comprising first trenches of said plurality of trenches for at least one MIMCap and defining a second region of said inter-level dielectric comprising second trenches of said plurality of trenches for a plurality of conductive lines; depositing a conductive liner over the inter-level dielectric and within the trenches of said first and second regions; depositing a seed layer over the conductive liner; depositing a resist over the seed layer; selectively removing the resist over the seed layer in the inter-level dielectric second region and leaving resist over the seed layer in the inter-level dielectric first regions; depositing a first conductive material within the inter-level dielectric second region trenches to overfill the trenches and to form said plurality of conductive lines; removing the resist covering the first region; depositing a MIMCap dielectric over the first conductive material within the second region trenches and over the first conductive layer within the first region trenches; and depositing a second conductive material over the MIMCap dielectric within the first region trenches to form a MIMCap top plate, wherein the second conductive material overfills the first region trenches.
