Abstract
Abstract Integrated circuit chips are carried on the front of a substrate. Printed circuitry and other components on the front of the substrate aid in the connection of and operation of the circuit of which the integrated circuit chip forms a part. Furthermore, electronically controlled display devices such as light-emitting diodes can be positioned on the front of the substrate and interconnected into the circuit to be operated thereby. These components on the front of the substrate are hermetically sealed by means of a cover sealed to and extending over the front of the substrate. Thus, the substrate forms a part of the hermetically sealed unit.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
183 words
A package for packaging components of a digital electronic watch movement in a watch case comprising: a substantially flat substrate having a peripheral edge and a face and a back, said substrate being fabricated from insulative material; at least one bare integrated circuit chip secured to said face of said substrate; an electronically controlled digital display device mounted on the face of said substrate; means for electrically coupling said integrated circuit chip to said display device; a cover positioned over the portions of said substrate which include said integrated circuit chip and said display device, said cover being substantially flat where it extends over said substrate and having downturned flanges along the edge of said cover, said cover having a transparent window therein positioned over said display device, said cover being optically opaque away from said window said cover being attached at its downturned flanges to the front of said substrate and spaced by said flanges over said display device and said chip to enclose the integrated circuit chip and display device within a protected volume defined by said flanges, cover, and substrate.
Claim 2
Dependent Claim
183 words
A package for packaging components of a digital electronic watch movement in a watch case comprising: a substantially flat substrate having a peripheral edge and a face and a back, said substrate being fabricated from insulative material; at least one bare integrated circuit chip secured to said face of said substrate; an electronically controlled digital display device mounted on the face of said substrate; means for electrically coupling said integrated circuit chip to said display device; a cover positioned over the portions of said substrate which include said integrated circuit chip and said display device, said cover being substantially flat where it extends over said substrate and having downturned flanges along the edge of said cover, said cover having a transparent window therein positioned over said display device, said cover being optically opaque away from said window said cover being attached at its downturned flanges to the front of said substrate and spaced by said flanges over said display device and said chip to enclose the integrated circuit chip and display device within a protected volume defined by said flanges, cover, and substrate.
Claim 3
Dependent Claim
68 words
The package of claim 1 wherein said transparent area in the cover is created by an opening in said cover, said opening being recessed and defined on the bottom by a depressed flange, said opening having a transparent material of approximately the same thickness as the depth of the recess hermetically sealed against said flange, said transparent material being substantially coplanar with the top surface of said cover.
Claim 4
Dependent Claim
24 words
The package of claim 1 wherein a mounting means is engaged against said annular area of substrate for mounting said substrate within the watchcase.
Claim 5
Dependent Claim
30 words
The package of claim 2 wherein both the cover is hermetically sealed to the substrate and the transparent material is hermetically sealed to the cover by means of an adhesive.
Claim 6
Dependent Claim
13 words
The package of claim 4 wherein the substrate is formed of ceramic material.
Claim 7
Dependent Claim
13 words
The package of claim 4 wherein the substrate is formed of vitreous material.
Claim 8
Dependent Claim
24 words
The package of claim 5 wherein a mounting means is engaged against said annular area of substrate for mounting said substrate within the watchcase.
Claim 9
Dependent Claim
23 words
The package of claim 7 wherein the hermetically sealed zone defined by the seal, substrate, and cover is filled with an inert gas.
Claim 10
Dependent Claim
16 words
The package of claim 8 wherein the electronically controlled display device is of the light-emitting type.
Claim 11
Dependent Claim
25 words
The package of claim 9 wherein said transparent material has filter characteristics which passes substantially only the wavelengths of the light-emitting electronically controlled display device.
