    摘要: An improved varactor diode (40) is obtained by providing a substrate (41) having a first surface (43), in which are formed a P+ region (53, 46) proximate the first surface (43), a first N region (54, 45) located beneath the P+ region (53, 46), an N well region (56, 44) located beneath the first N region (54, 45) and a first P counter-doped region (55) located between the first N region (54, 45) and the N well region (56, 44), thereby forming an P+NPN structure for the varactor diode. In some embodiments, a second P-type counter-doped region (59) is provided within the N-well region (56, 44) so as to reduce the N doping concentration within the N well region (56, 44) but without creating a further PN junction therein. The net doping profile (52) provides varactor diodes (40) having a larger tuning ratio than varactors (20) without such counter-doped regions. By interchanging N and P regions an N+PNP varactor is obtained.

    摘要: High frequency performance of (e.g., silicon) bipolar devices is improved by reducing the extrinsic base resistance Rbx. An emitter, an intrinsic base, and a collector are formed in a semiconductor body. An emitter contact has a region that overlaps a portion of an extrinsic base contact. A sidewall is formed in the extrinsic base contact proximate a lateral edge of the overlap region of the emitter contact. The sidewall is amorphized during or after formation so that when the emitter contact and the extrinsic base contact are, e.g., silicided, some of the metal atoms forming the silicide penetrate into the sidewall so that part of the highly conductive silicided extrinsic base contact extends under the edge of the overlap region of the emitter contact closer to the intrinsic base, thereby reducing Rbx. Smaller Rbx provides transistors with higher fMAX.

    摘要: A process of forming an electronic device can include providing a first interconnect over a substrate having a primary surface, depositing a first insulating layer over the first interconnect, and patterning the first insulating layer to define an opening extending towards the first interconnect. The process can also include depositing a second insulating layer over the first insulating layer to seal the opening and form a cavity within the first opening, and forming a second interconnect over the first and second insulating layers. The cavity can be disposed between the first interconnect and the second interconnect. In another aspect, an electronic device can include a first interconnect, a first insulating layer defining a cavity, and a second interconnect. The cavity can be disposed between the first interconnect and the second interconnect, and a via may not be exposed within the cavity.

    摘要: High frequency performance of (e.g., silicon) bipolar devices (100) is improved by reducing the extrinsic base resistance Rbx. Emitter (160), intrinsic base (161, 163) and collector (190) are formed in a semiconductor body (115). An emitter contact (154) has a region (1541) that overlaps a portion (1293, 1293′) of an extrinsic base contact (129). A sidewall (1294) is formed in the extrinsic base contact (129) proximate a lateral edge (1543) of the overlap region (1541) of the emitter contact (154). The sidewall (1294) is amorphized during or after formation so that when the emitter contact (154) and the extrinsic base contact (129) are, e.g., silicided, some of the metal atoms forming the silicide penetrate into the sidewall (1294) so that part (183) of the highly conductive silicided extrinsic base contact (182, 183) extends under the edge (1543) of the overlap region (1541) of the emitter contact (154) closer to the intrinsic base (161, 163), thereby reducing Rbx. Smaller Rbx provides transistors with higher fMAX.

    摘要: High frequency performance of (e.g., silicon) bipolar devices is improved by reducing the extrinsic base resistance Rbx. Emitter, base and collector regions are formed in or on a semiconductor substrate. The emitter contact has a portion that overhangs a portion of the extrinsic base contact, thereby forming a cave-like cavity between the overhanging portion of the emitter contact and the underlying regions of the extrinsic base contact. When the emitter contact and the extrinsic base contact are silicided, some of the metal atoms forming the silicide penetrate into the cavity so that the highly conductive silicided extrinsic base contact extends under the edge of the emitter contact closer to the base itself, thereby reducing Rbx. Smaller Rbx provides transistors with higher fMAX.
