If the result was not satisfactory, the discrete elements were changed in value and/or type, until the electrical specifications were met. This empirical procedure was called breadboarding. With the advent of the integrated circuit this method was no longer appropriate, mainly for two reasons:

Unless stated otherwise, the device structure considered here is that of an .-channel transistor. In most cases, a .-channel device only needs a change of sign to produce its model formulas.

They are determined by the dimensions of the mask, corrected for such effects as outdiffusion, underetching, misalignment of masks, encroachment of isolation oxides, etc.

In the latter case a channel implant is often added for achieving better process control. Figs. 9.1 a and 9.1 b give a cross-section of the JFET and the MESFET, respectively.
