Abstract
A hybrid-type device is constructed using bumps 4A, which electrically connect the electrodes of function elements 2 arranged on a first plane substrate 1 to those of function elements 7 arranged on a second plane substrate 6, the bumps being formed from conductive thermoplastic resin. Since the thermoplastic resin does not have a definite melting point, the bumps do not short-circuit when one substrate is heated and the two substrates are pressed towards one another while the bumps soften. Further, should a void form under a bump during the pressing, the air in the void is readily forced out through the softened bumps by pressure. For these reasons, a highly reliable device is available. <IMAGE>
Description
HYBRID-TYPE DEVICE AND MANUFACTURING METHOD THEREOF
BACKGROUND OF THE INVENTION
FIELD OF THE INVENTION
The present invention relates to a hybrid-type device and its manufacturing method. More particularly, the invention relates to a hybrid-type device in which a first plane substrate and a second plane substrate are joined by a column-like conductor (bump) so that the device is integrated, and to a method of manufacturing such device.
In the device, function elements are formed either one- or two-dimensionally within a plane. The electrode of each function element is arranged, corresponding to each function element, either one- or two-dimensionally on the first plane substrate, and additional function elements and their electrodes are arranged on the second plane substrate so as to oppose the above-mentioned function elements and their electrodes.
DESCRIPTION OF THE RELATED ART
FIG. 1 is a cross section showing the major components of a conventional hybrid-type device. As shown in FIG. 1, function elements 2, such as arrays of photodiodes, are arranged on a first plane substrate 1. The electrodes (not shown) of the function elements 2 are electrically connected through underlying metal strips 3 to bumps 4.
The space between the electrodes of the function elements 2 and the underlying metal strips 3 is coated with an insulating film 5. Another function elements 7, such as charge coupled devices (CCDs), are disposed on a second plane substrate 6 so as to oppose the aforesaid function elements 2. The electrode (not shown) of each function element 7 is provided with an underlying metal strip 8. A space between the electrodes of the function elements 7 and the underlying metal 8 is coated with an insulating film 9.
The bump 4 is formed by metal, such as indium.
The conventional hybrid-type device is constructed as described above, bumps 4 are formed of a metal such as indium. There are two methods of integrating or hybridizing the device shown in FIG. 1 to make a hybridtype device. In other words, the following two methods are available to integrate the device.
As shown in FIG. 2, the first method is the one where two plane substrates 1, 6 are joined by applying pressure to the both substrates 1, 6. In this case a void 10, a closed space, between the underlying metal strip 8 and the bump 4 may be left. Under this condition, when a temperature applied to the device changes, the air pressure in the void 10 will change, thereby causing the bump 4 and the underlying metal strip 8 to separate from each other.
Thus the two plane substrates 1, 6 fail to be joined, resulting in serious problems, such as lessening the device's reliability.
The second method is devised to remove the void 10 as explained in the first method. The second plane substrate 6 is heated before it is pressed against the first plane substrate 1. To be more specific, since the melting point of indium is about 154 OC, when the second plane substrate 6 is pressed against the first plane substrate 1 after the second substrate 6 is heated up to 1600 C, the bump 4 is heated, melted and then attached by the thermal conductivity of the second plane substrate 6 from the tip thereof. When the second method is used, because indium has a high thermal conductivity coefficient, the entire bumps 4 are melted unless temperature for the second plane substrate 6 is precisely controlled. As a result, as shown in FIG. 3, the bumps 4 short-circuit due to a molten bump 11. This is a problem arising from the second method.
As has been described, the conventional hybrid-type device has the following two problems: two substrates cannot be joined because the bumps 4 and the underlying metal strips 8 separate from each other; two substrates cannot be joined since the bumps 4 short-circuit each other.
SUMMARY OF THE INVENTION
The present invention is achieved to overcome the above-described problems in the conventional device. It is an object of the present invention to provide a highly reliable hybrid-type device and its manufacturing method.
Accordingly, an object of the present invention is to provide a hybrid-type device comprising: a first plane substrate; a plurality of first function elements arranged either one- or two-dimensionally on the first plane substrate; a second plane substrate; a plurality of second function elements arranged either one- or two-dimensionally on the second plane substrate so as to oppose the first function elements; and a conductive thermoplastic resin member for electrically connecting electrodes of the first function elements to electrodes of the second function elements and for integrating the first and second plane substrates.
Another object of the present invention is to provide a method of manufacturing a hybrid-type device comprising the steps of: providing a conductive thermoplastic resin member on a first plane substrate for electrically connecting to electrodes of first function elements, wherein a plurality of the first function elements are disposed on the first plane substrate either one- or twodimensionally; heating a second plane substrate to a predetermined temperature, wherein a plurality of second function elements are disposed on the second plane substrate either one- or two-dimensionally so as to oppose the first function elements; and pressing the first plane substrate against the second plane substrate thereby electrically connecting between the first and the second function elements by the conductive thermoplastic resin and integrating the first and second plane substrates.

Electrodes (not shown) of the function elements 2 are electrically connected through underlying metal strips 3 to column-like bumps 4A. The space between the underlying metal strips 3 is coated with an insulating film 5.
The aforesaid bump 4A is made of conductive thermoplastic resin, which is obtained by uniformly dispersing metal powder over thermoplastic resin. The thermoplastic resin may be selected from the groups consisting of polyethylene resin (softening point: 110 to l200C), polypropylene resin (softening point: 120 to 1300
C), polyethylene terephtalate resin (softening point: 1500 C or less) and polyethylene - vinyl acetate copolymer
(commonly known as hot melt resin: softening point: 100 to 1500 C). As regards the metal powder to be dispersed, silver (Ag), gold (Au), silver-palladium alloy (AgPd), silver-platinum alloy (AgPt), copper (Cu), etc. may be used.
Additional function elements 7, such as charge coupled devices (CCDs), are disposed on a second plane substrate 6 so as to oppose the aforesaid function elements 2.
Electrode (not shown) of each function element 7 is provided with an underlying metal strip 8. The space between the underlying metal strips 8 is coated with an insulating film 9.
In order to join the plane substrates 1 and 6 of such a hybrid-type device as constructed above, the plane substrate 6 is heated up to a predetermined temperature before the plane substrate 1 is lowered to be attached by using pressure on the plane substrate 6. At this time, the bump 4A is heated from its front end, which begins to alter the bumps plasticity. When the device comes to the state described in FIG. 1, application of heat and pressure is stopped. Since the thermoplastic resin of the bump 4A does not have a high thermal conductivity coefficient, unlike metal, nor has it a definite melting point, the bumps 4A do not short-circuit each other as shown in FIG. 3 even if
they melt suddenly.Furthermore, should a void 10 as shown
in FIG. 2 be made, applied pressure forces the air within
the void 10 out without any hindrance owing to the softened bumps 4A, whereby no space is left in the void 10.
Although in this embodiment the bumps 4A are disposed
on the first plane substrate 1, they may be arranged on the
second plane substrate 6. Moreover, with the same effect
as described above, a liquid crystal, a liquid crystal
panel, etc. may be utilized as the function element 2, in
addition to the photodiode utilized in this embodiment.
Thin film transistors (TFTs) and others can also be used as
a function element 7, with the same effect as described
above, though charge coupled devices (CCDs) are used in
this embodiment.
The invention has been described in detail with
particular reference to the preferred embodiment thereof,
but it will be understood that variations and modifications
of the invention can be made within the spirit and scope of
the invention.
