    • A bipolar transistor (100) and a method for forming the same. A base-link diffusion source layer (118) is formed over a portion of the collector region (102). The base-link diffusion source layer (118) comprises a material that is capable of being used as a dopant source and is capable of being etched selectively with respect to silicon. A barrier layer (119) is formed over the base-link diffusion source layer (118). A base electrode (114) is formed over at least one end portion of the barrier layer (119) and base-link diffusion source layer (118) and the exposed portions of the barrier layer (119) and underlying base-link diffusion source layer (118) are removed. An extrinsic base region (110) is diffused from the base electrode (114) and a base link-up region (112) is diffused from the base-link diffusion source layer (118). Processing may then continue to form an intrinsic base region (108), emitter region (126), and emitter electrode (124).

    • A lateral PNP transistor (LPNP) (102) having the low resistance base buried N+ region (114) removed from below the emitter region (118). This leaves a high resistance n-well (116) below the emitter. The resistance from the center of the emitter region (118) to the N+ buried region (114) is greater than the resistance at the periphery of the emitter region (118) to the N+ buried region (114). Debiasing will occur in the center of the emitter region (118) where the parasitic base current is generated. Thus, the ratio of parasitic current to active collector current and peak beta will improve.
    • 具有从发射极区域(118)下方去除的低电阻基极掩埋N +区域(114)的横向PNP晶体管(LPNP)(102)。 这使得在发射极下方留下高电阻n阱(116)。 从发射极区域(118)的中心到N +掩埋区域(114)的电阻大于在发射极区域(118)周围到N +掩埋区域(114)的电阻。 在发生寄生基极电流的发射极区域(118)的中心发生偏移。 因此,寄生电流与主动集电极电流和峰值β的比值将会提高。
