Stick diagrams are those which convey layer information through
Stick diagrams are those which convey layer information through color codes. Thickness is not considered in this stick diagram representation.
Which color is used for n-diffusion?
Green color is used to show the presence of n-diffusion layer. The n-type diffusion will dope the source or drain region in the p-well region.
Which color is used for implant?
Yellow color is used to represent implant layer.
Which color is used for contact areas?
Black color is used to represent contact areas. This is the part where two different touch or cross each other.
Which color is used for polysilicon?
Red is used to represent polysilicon layers. It is a semi-conductor like material and is a hyper pure form of silicon.
Which color is used for polysilicon 2?
Orange color is used to represent polysilicon-2 layer.
Which color is used for buried contact?
Brown color is used to represent buried contact. Buried contact is most widely used, subject to fewer design rule restrictions and are smaller in area.
n and p transistors are separated by using
Demarcation line separates n and p transistors. Demarcation line is similar to dotted line in brown.
_______ layer should be over ______ layer
Polysilicon layer should be over n-type layer. This is the standard pattern used in stick diagram representation.
How is nMOS depletion mode transistor represented?
nMOS depletion mode transistor can be represented by using polysilicon over ntype layer and with an implant.
