Abstract
Abstract A multi-component microcircuit package is formed from a plurality of separate components which are secured together to form a lower package portion using a base and a continuous composite side wall frame having irregularities on its upper surface as a result of the component junctions. Secured to the top of this side wall frame is a one-piece continuous top frame member having a uniform upper surface. This top frame member covers the irregularities present in side wall frame and provides a surface more suitable for hermetic sealing of a package lid to the package.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
104 words
A hermetically sealable multi-component microcircuit package comprising: (a) a lower package portion having a base and a continuous composite side wall frame, said composite side wall frame comprising at least two separate side wall members secured together in such a manner that the top surface of said composite side wall frame has at least one side wall member-to-side wall member junction; said junction irregularities in said top surface and (b) a one-piece, continuous top frame member secured to the top surface of said side wall frame, said top frame member providing a uniform upper surface onto which a package lid may be hermetically sealed.
Claim 2
Dependent Claim
104 words
A hermetically sealable multi-component microcircuit package comprising: (a) a lower package portion having a base and a continuous composite side wall frame, said composite side wall frame comprising at least two separate side wall members secured together in such a manner that the top surface of said composite side wall frame has at least one side wall member-to-side wall member junction; said junction irregularities in said top surface and (b) a one-piece, continuous top frame member secured to the top surface of said side wall frame, said top frame member providing a uniform upper surface onto which a package lid may be hermetically sealed.
Claim 3
Dependent Claim
14 words
The package of claim 1 wherein said side wall members are made of metal.
Claim 4
Dependent Claim
12 words
The package of claim 1 wherein said base is made of metal.
Claim 5
Dependent Claim
17 words
The package of claim 2 wherein said side wall members are secured to one another by brazing.
Claim 6
Dependent Claim
13 words
The package of claim 1 wherein said base is made of ceramic material.
Claim 7
Dependent Claim
19 words
The package of claim 1 wherein said base is integrally formed with at least one of said side walls.
Claim 8
Dependent Claim
23 words
The package of claim 1 wherein said side wall frame is provided with at least one aperture through which lead wire can pass.
Claim 9
Dependent Claim
14 words
The package of claim 1 wherein said top frame member is made of metal.
Claim 10
Dependent Claim
22 words
The package of claim 1 wherein said top frame member is substantially congruent to the top surface of said side wall frame.
Claim 11
Dependent Claim
23 words
The package of claim 8 wherein said top frame member is secured to the top surface of said side wall frame by brazing.
Claim 12
Dependent Claim
19 words
The package of claim 8 wherein said top frame member is chemically milled to provide said uniform upper surface.
Claim 13
Dependent Claim
19 words
The package of claim 8 wherein said top frame member is stamped out to provide said uniform upper surface.
Claim 14
Dependent Claim
93 words
A hermetically sealable all metal, multi-component flat microcircuit package comprising: (a) a lower package portion having a metallic base brazed to a continuous composite side wall frame, said composite side wall frame being formed by brazing a plurality of metallic side wall members together, the top surface of said side wall frame having at least one brazed junction thereon; and (b) a one-piece continuous metallic top frame member brazed to the top surface of said side wall frame to provide a uniform top surface onto which a package lid may be hermetically sealed.
Claim 15
Dependent Claim
93 words
A hermetically sealable all metal, multi-component flat microcircuit package comprising: (a) a lower package portion having a metallic base brazed to a continuous composite side wall frame, said composite side wall frame being formed by brazing a plurality of metallic side wall members together, the top surface of said side wall frame having at least one brazed junction thereon; and (b) a one-piece continuous metallic top frame member brazed to the top surface of said side wall frame to provide a uniform top surface onto which a package lid may be hermetically sealed.
