Abstract
Abstract An improved ceramic substrate for supporting, cooling and interconnecting components on both surfaces of a substrate includes a plurality of coolant carrying channels separated by fins and extending through the substrate generally parallel to the surfaces of the substrate; and a plurality of routed vias for interconnecting component terminations on opposite surfaces of the substrate which are not aligned with each other and with a fin; each routed via includes an internal via extending through a fin and a surface blind via extending inwardly from each surface, and at least one transverse segment interconnecting one end of the internal via to one of the surface blind vias.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
126 words
An improved ceramic substrate for supporting, cooling and interconnecting components disposed on opposite surfaces of the substrate, comprising: a plurality of coolant carrying channels separated by fins and enclosed within the interior of said substrate between the components on opposite surfaces and extending through said substrate generally parallel to said surfaces of said substrate; and a plurality of routed vias for interconnecting said components disposed on opposite surfaces of the substrate by component terminations which are not aligned with each other and with a fin, each said routed via including an internal via extending through a fin, a surface blind via extending inwardly from each surface, and at least one transverse segment interconnecting one end of said internal via to one of said surface blind vias.
Claim 2
Dependent Claim
126 words
An improved ceramic substrate for supporting, cooling and interconnecting components disposed on opposite surfaces of the substrate, comprising: a plurality of coolant carrying channels separated by fins and enclosed within the interior of said substrate between the components on opposite surfaces and extending through said substrate generally parallel to said surfaces of said substrate; and a plurality of routed vias for interconnecting said components disposed on opposite surfaces of the substrate by component terminations which are not aligned with each other and with a fin, each said routed via including an internal via extending through a fin, a surface blind via extending inwardly from each surface, and at least one transverse segment interconnecting one end of said internal via to one of said surface blind vias.
Claim 3
Dependent Claim
35 words
The improved ceramic substrate for supporting cooling and interconnecting components disposed opposite on surfaces of the substrate of claim 1 in which the other of said surface blind vias is aligned with said interconnect via.
Claim 4
Dependent Claim
42 words
The improved ceramic substrate for supporting cooling and interconnecting components disposed on opposite surfaces of the substrate of claim 1 in which there is a second transverse segment interconnecting the other end of said internal via with the other surface blind via.
Claim 5
Dependent Claim
35 words
The improved ceramic substrate for supporting, cooling and interconnecting components disposed on opposite surfaces of the substrate of claim 1 in which at least one of said transverse segments extends across more than one channel.
Claim 6
Dependent Claim
40 words
The improved ceramic substrate for supporting, cooling and interconnecting components disposed on opposite surfaces of the substrate of claim 1 in which at least one of said transverse segments extends along a said channel and across at least one channel.
Claim 7
Dependent Claim
34 words
The improved ceramic substrate for supporting, cooling and interconnecting components disposed on opposite surfaces of the substrate of claim 1 in which at least one of said transverse segments extends along a said channel.
