A bridge abutment with wings perpendicular to the face which act as counterforts; a very stable abutment, often used for architectural effect. McGraw-Hill
STRETCH HANDLES AND AUTO-ABUTMENT . For example, a parameterized transistor layout design could be developed through this Python API, and the
The method further comprises performing an analysis to identify cell abutment cases present in the semiconductor device and top and the n-transistors at the bottom. Also the abutment box that encloses the cell is marked. This is only a Þctitious border around the cell that deÞnes in what area to place different objects. Vdd Vout Va Va Vb Vb nMOS network pMOS network. Chapter 2 — Project Basics 5 For an N-well process, the layout for a transistor pair (like an inverter) is presented in Figure 3a. In this layout, the connection in the drain region is implemented with contacts and by abutment in the source region.

THE NEW LAYOUT STYLE In our approach, at the cell level, transistors are still placed using linear matrix style, i.e., two horizontal diffusion lines parallel to power/ground rails. In this style transistors are connected, as much possible, by abutment, aiming to reduce diffusion capacitances.
27 Via-on-via Min spacing Line -on via Min spacing, can The abutment sever as well as auto abutment are enabled in it. These 4 transistors just form 2 transmission gates as shown in the schematic below where the metal Include one substrate contact for each connection between a transistor and a power bus.
The transistor solution works for all logic voltages, because the transistor will turn on with any drive voltage above 0.7 V. It could even be used to translate between a 12 V or 24 V input to a 3.3 V or 5 V output, as long as the input resistor R2 is large enough to …

Consequently, it is the most important factor to be considered. There are two essential conditions for two transistors A and B to be abutted:

Data signals run vertically in second metal over the bit slices. Power, ground, and control lines are routed in first metal or poly between the bit slices.

This tutorial covers transistor operational theory, functional testing, history, biasing, type identification, terms, characteristic curves and load lines.
Abutment reduces transistor source/drain diffusion area and hence cell-width by merging same diffusion nets of adjacent transistors [2]. However maximal abutment does not always assure the best layout for routing intensive cells and may even result in unroutable or routing congested solution, causing Transistor Folding . . . .
