This subclause specifies the ARM entities for this
module. Each ARM application entity is an atomic element that
embodies a unique application concept and contains attributes
specifying the data elements of the entity. The ARM
entities and definitions are specified below.
A Bare_die is a type of
Part_usage_view
that is used to describe the physical shape and function of a semiconductor device.
NOTE 1
In the PCA domain an occurrence of a Bare_die may be installed into an occurrence of a
Package
to realize a
Packaged_part,
an occurrence of which is then mounted in the assembly. In this role of performing a function, a Bare_die has terminals.
NOTE 2
In the PCB domain an occurrence of a Bare_die may be installed into the design of an
Interconnect_module_design_view
to realize an embedded component. In this role, the external surfaces of the Bare_die will be important as they form part of
the location information for the occurrence.
NOTE 3
A Bare_die implements electrical functionality. It is not necessary to exchange Bare_die information for parts such as
molded or ceramic resistors where there is not a separately identifiable and common industry understanding of a die.
NOTE 4
In the PCA domain an occurrence of a Bare_die may be mounted directly onto the occurrence of a usage view of a PCB.
NOTE 5
The existence of oxide or other thin contaminate protection is considered normal for a Bare_die.
