CMOS Manufacturing Steps
<Advantages of p-well over n-well CMOS>
- p well technology may be the better choice for pure static logic, in which a good balance between the performance of both MOS device types is beneficial.
- p well CMOS is less susceptible to field inversion problems than n well CMOS
- It is easier to form a p-retrograde well than an n- retrograde well, since boron ions penetrate deeper than arsenic or phosphorus ions at the same implant energy.
<Twin well technology>
Two device types perform similarly as channel lengths approach 0.5μm, it is useful to provide symmetrical n- and p-channel devices.
Body doping of both transistor types maintain adequate threshold voltage levels.
It is compatible with the technologies of either isolation by selective epitaxial growth or trench isolation. Self aligned channel stops can be easily implemented in the twin well approach, allowing the spacing between n- and p-channel devices to be reduced.
