摘要

本文给出了一种高性能硅双极晶体管结构的实验结果,该结构利用单层多晶硅作为基极和发射极触点。这种结构被称为STRIPE(自对准沟槽隔离多晶硅电极),提供了一个2.0-μm的发射极/基极多晶硅接触分离。采用传统的0.8 μ m光刻技术,可以实现0.4 μ m的射极宽度。这些尺寸与双聚结构所能达到的尺寸相当。采用STRIPE结构,已制造出截止频率高达33.8 GHz的晶体管

STRIPE-a high-speed VLSI bipolar technology featuring self-aligned single-poly base and submicron emitter contacts
Experimental results are presented for a high-performance silicon bipolar transistor structure utilizing a single layer of polysilicon for both the base and emitter contacts. This structure, called STRIPE (self-aligned trench-isolated polysilicon electrodes), provides a 2.0-μm emitter/base polysilicon contact separation. A 0.4-μm emitter width is achieved with conventional 0.8-μm optical lithography. These dimensions are comparable to those achievable with double-poly structures. Using the STRIPE structure, transistors have been fabricated with cutoff frequency as high as 33.8 GHz
