Abstract

Fig. 1 shows a silicon chip 2 that supports Josephson devices (not shown). Devices on chip 2 are connected to components off the chip by conductive lines 3 that are formed on the chip. Supporting chip 2 and other supports (not shown) are mounted in grooves 4 on a silicon device 5 that forms a circuit board. At the position of each conductive line 3, circuit board 5 has a generally rectangular hole 6 that extends completely through the board, as can be seen in Fig. 2. Conductive lines 7 are formed on the inner edge of the hole, and extend across the bottom of the hole and a portion of the board 5. Electrical contact between a conductive line 3 and a corresponding conductor 7 is made by a globule of mercury 9.

Interconnection System for Josephson Devices

Fig. 1 shows a silicon chip 2 that supports Josephson devices (not shown). Devices on chip 2 are connected to components off the chip by conductive lines 3 that are formed on the chip. Supporting chip 2 and other supports (not shown) are mounted in grooves 4 on a silicon device 5 that forms a circuit board. At the position of each conductive line 3, circuit board 5 has a generally rectangular hole 6 that extends completely through the board, as can be seen in Fig. 2. Conductive lines 7 are formed on the inner edge of the hole, and extend across the bottom of the hole and a portion of the board 5. Electrical contact between a conductive line 3 and a corresponding conductor 7 is made by a globule of mercury 9.

A conductor 7 can extend along the lower surface of board 5 to provide electrical contact from one well to another well or to provide electrical contact from a well to an external connector structure 10 that is shown in detail in Fig. 2. The circuit board and chip structure of Fig. 1 can be combined with an additional slotted board 11 similar to board 5 to form a rigid box-like structure that is connected by suitable means represented by a connecting rod 12. The upper board 11 may have only a slot 4 for physically locating the chip 2 or it may have the well structure of board 5 and/or the external connector structure 10 (not shown).

As Fig. 2 shows, the connector structure 10 comprises a thin compliant layer 14 tha...
