Definitions
- the present invention relates to a method for the interconnection of stacked packages, as well as the device resulting therefrom, each of the packages encapsulating an electronic component such as a semiconductor chip containing for example an integrated circuit, or an electronic circuit or a sensor ; these components will be referred to below without distinction by the terms components or tablets.
- the object of the present invention is to avoid the above limitations by stacking and interconnecting no longer tablets, but boxes containing the components and using the faces of the stack as interconnection surfaces.
- the wafers in the package are available on the market at prices lower than those charged for the pellets alone, mainly for reasons of the quantities produced, and their testing is also easier and therefore less expensive.
- the subject of the invention is an interconnection method as defined by claim 1, as well as a device comprising stacked and interconnected housings as defined by claim 6.
- FIG. 1 therefore illustrates an embodiment of the method according to the invention.
- the first step of the method identified 11, consists of stacking boxes, each containing an electronic component, for example a semiconductor chip in which an integrated circuit is produced.
- the boxes are each further provided with connection pins.
- Figure ra illustrates an example of such a housing.
- a housing generally marked 2, for example rectangular; it has connection pins 21 emerging for example on two of its sides, for example the short sides.
- a cut was made in the housing along its long length; there are the patch 20, generally arranged on an electrically conductive sheet 22, as well as two pins 21 extending inside the housing 2 and connected by conductive wires
- the sheet 22 and the pins 21 are formed in the same conductive sheet, the parts 21 and 22 being held integral by parts located at the outside a certain perimeter, a subsequent cutting being carried out along this perimeter.
- the various preceding elements are embedded in a plastic material 24 forming the housing, epoxy resin for example.
- the box shown can be for example of the TSOP type (for Thin Small Outline Package).
- FIG. 2b represents another example of a box capable of being used in the device according to the invention.
- FIG. 2b similar to Figure 2a, there is a housing
- the housing further comprises a plate 23, made of a material which is a good conductor of heat and forming a heat sink, this plate constituting at least partially the bottom of the housing 2.
- a heat sink can be produced from the sheet 22.
- the latter is extended on one of the sides of the housing, preferably on a side without pins.
- FIG. 3 represents, seen in perspective, the stack 3 of the housings 2 produced during step 11, the housings being for example as shown in FIG. 2a.
- the faces of the stack which comprise the pins 21 have been identified by 31 and 32, by 33 the upper face of the stack (parallel to the housings 2) and by 34 one of the other lateral faces.
- the stacked boxes are joined together by coating the assembly with an electrically insulating material, such as a polymerizable resin, epoxy for example.
- an electrically insulating material such as a polymerizable resin, epoxy for example.
- the coating material is chosen so that it is thermo-mechanically adapted to the material forming the package, so as to facilitate the thermal dissipation of the pellets by conduction through the package and coating, and to avoid ruptures possibly due to too large differences in the values of the expansion coefficients of the materials.
- the next step (13, FIG. 1) consists in cutting the stack so that the pins 21 of the different housings are flush with the faces of the stack, as well as, if necessary, the thermal drains.
- FIG. 4a represents the result of this step 13, in the case of the boxes illustrated in FIG. 2a.
- Figure 4b is a view similar to that of Figure 4a, but in the case of the housings illustrated in Figure 2b.
- the stack still referenced 3, is formed of housings 2 which each include a heat sink 23. The latter are flush with the lateral faces of the stack, that is to say the face 34 and the face which is opposite to it, as the pins 21 of the boxes are flush with the faces 31 and 32.
- FIG. 4c is a variant of the previous figure, where a heat sink 36, for example a finned radiator, has been placed on the face 34 of the stack 3 where the thermal drains are flush 23.
- a heat sink 36 for example a finned radiator
- a similar sink can also be used. be arranged on the face of the stack which is opposite to the face 34 and where the drains 23 can also be flush.
- the fixing of the radiator 36 can for example be carried out by bonding, using an epoxy adhesive for example, either directly on the face of the stack, or after metallization thereof as described below.
- the next step (14, FIG. 1) consists in depositing one (or more) conductive layer (s), metallic (s) for example, on all of the faces of the stack 3 previously produced.
- the next step (15, FIG. 1) consists in making connections on the faces of the stack 3, from the previous metal layer, connecting the pins 21 to each other.
- FIG. 5 is a fractional view of a stack according to the invention, on which examples of connection are illustrated.
- the stack 3 is shown, the faces 31, 33 and 34 of which are visible. Also shown are the dotted housings 2 and their connection pins 21, flush with the face 31.
- the stack 3 has on one or more of its faces, for example on the face 33, studs 35, called stacking studs , for its electrical connection to external circuits.
- the pins 21 are both interconnected with one another and, when necessary, connected to the stacking pads 35 by means of connections C.
- the figure shows the case where the boxes 2 contain memories; in this case, all of their homologous pins are connected together and to a stacking pad 35 except one, marked 24, for each of the housings.
- This pin 24, which corresponds to the memory selection input, is connected for each box individually to a separate stacking pad 35.
- the boxes have more pins such as 24, requiring individualization, the same is done for each.
- FIGS 6a and 6b illustrate in more detail an embodiment of the connections C.
- FIG. 6a represents a fractional and enlarged view of a piece A of the stack of FIG. 5, where we see a connection C and a stacking pad 35.
- FIG. 6b is a sectional view along an axis BB of figure 6a.
- Each of the connections C is formed by two etchings 51 and
- the stacking pads 35 can advantageously be produced by the same laser etching technique as shown in FIG. 6a.
- Another method of making connections C consists first of making grooves in the coating material of the stack 3, at the level where the pins 21 are flush, so as to clear the end of the latter, and operate these grooves according to the drawing used for connections C; these grooves can be produced by laser; then an electrically conductive layer (metal for example) is deposited over the entire stack, faces and grooves; finally, the conductive layer is removed from the flat surfaces of the stack (by polishing or by laser for example), so as to only allow it to remain in the grooves where it makes the desired connections.
- these grooves can be produced by laser; then an electrically conductive layer (metal for example) is deposited over the entire stack, faces and grooves; finally, the conductive layer is removed from the flat surfaces of the stack (by polishing or by laser for example), so as to only allow it to remain in the grooves where it makes the desired connections.
- connections C are of course possible, such as photolithography for example.
- connections C and the stacking pads 35 can be arranged on any faces of the stack or even all of the faces, the choice being made according to the application.
- this can be made of an electrically insulating material (aluminum nitride, silicon carbide, for example) if it is desired to have the pins 21 and / or form connections C on the faces where the drains 23 are flush.
- the last step of the process represented in FIG. 1, marked 16, consists of fixing on the stack of connection pins, as illustrated in FIG. 7.
- a stack 3 is not necessarily provided with connection pins: it can be mounted "flat”, that is to say either by direct welding on its stacking pads, on a printed circuit, the boxes then being arranged parallel or perpendicular to the circuit, or on another stack, either by means of suitable grids.
- a block is stacked, themselves formed from stacked boxes, to increase the number of boxes processed simultaneously and, consequently, reduce the cost. This variant is shown in Figure 8.
- the first step, 11, consists as before of stacking the boxes to form a block.
- the second step, marked 10, consists in stacking a certain number of blocks thus obtained, by adding certain intermediate layers, as illustrated in FIG. 9. By way of example, it is thus possible to stack around twenty blocks.
- FIG 9 there is shown for example two blocks, 94 and 95, seen in section, each consisting of for example eight housings 2 and comprising for example each a heat sink 23, extending or not extending over the entire length of the housing .
- a shim 93 intended to subsequently allow the separation of the blocks; it is for this purpose of dimensions greater than those of the housings; it is for example in silicone.
- two substrates of the printed circuit type have also been placed on either side of each block, marked 91 and 92, making it possible to facilitate the routing of connections.
- the printed circuits are for example glued (layer 96) on the boxes 2 and made integral with each other by the interlayer 93.
- circuits 91 and 92 can also be replaced by insulating shims, epoxy for example. All of the blocks are then joined together by an insulating material D, as the boxes were previously (step 12), then cut or grinded (step 13).
- FIG. 9 represents the two blocks at the end of step 13.
- the strips are then stacked as described above for the boxes and several stacks can thus be produced collectively.
- the invention is not limited to the specific examples described above and different variants are possible. This is how the stack of boxes having substantially the same size has been illustrated in the figures, but this is not necessary: when the boxes are of different dimensions, the invention applies subject to putting all the boxes at the sides of the largest, using for each a support of the printed circuit type on which the box is connected, this printed circuit being able to be multilayer, thus facilitating the routing of the connections.
