Patent ID: 7521327

Claim:
A method of forming a bipolar device on a substrate having a collector, comprising the steps of: (a) forming an intrinsic base layer on said substrate; (b) forming a first conductor above said intrinsic base layer, wherein said first conductor has a substantially uniform conductance throughout; and (c) forming an emitter having at least a portion thereof extending over a portion of said first conductor; wherein: step (b) includes forming a first extrinsic base layer and silicidating said first extrinsic base layer prior to step (c) so as to form said first conductor; step (b) further includes forming a landing pad atop said first extrinsic base layer prior to silicidating said first extrinsic base layer; step (c) includes removing a portion of said landing pad to form an aperture; and step (c) further includes oxidizing said first extrinsic base layer beneath said aperture so as to form an oxidized region and removing at least a portion of said oxidized region to said intrinsic base layer.
