A HIGH VOLTAGE LINEAR COMPATIBLE INTEGRATED INJECTION LOGIC (I2L) STRUCTURE: PROCESS DESIGN AND SPECIFICATIONS

An integrated circuit processing schedule is presented that enables fabrication of both high speed I²L gates and high voltage linear type transistors on the same silicon starting substrate material. This process design circumvents conflicting processing requirements normally encountered in considering an I²L/Linear compatible structure by providing two separate epitaxial thicknesses for the I²L and linear section of the chip. The electrical characteristics of the I²L cells and the linear transistors are presented to illustrate their dependence on the doping conditions and are shown to be in contrast to each other. As a consequence of the separate epitaxial thicknesses, independence of the processing constraints is achieved. Experimental results of linear transistors and I²L devices fabricated using this processing schedule are presented and compared to calculated and computer simulations. Modifications to the basic process design is shown possible and enhanced performance of I²L devices results.
