Abstract

PURPOSE:To enable to mount normally an LSI pellet, without resulting in electric short of a lead wire, or troubles in the bonding operation, etc., by forming a cut section where a portion of a bonding pad as well as the ceramic layer having the pad thereon is cut at the tip of the bonding pad for a specific pin. CONSTITUTION:In a laminated ceramic package 8, a cut section 4 is provided where a portion of a bonding pad as well as the ceramic layer is cut at the tip of the bonding pad 2c for a specific pin. Where an LSI pellet 6 is mounted, bonding pads 7a-7e of the LSI pellet 6 and bonding pads 2a-2e of the package 8 are connected with a lead wire 5 respectively. In this case, though the lead wire between the bonding pads 7d, 2d passes near the tip of the neighboring bonding pad 2, electric short or troubles in bonding operation, etc., is not resulted, because the cut section 4 cut each ceramic layer is provided at the tip of the bonding pad 2c.

In a laminated ceramic package, the present invention provides a notch section at the tip of the bonding pad of a specific bottle by cutting a part of the bonding pad together with the ceramic layer in which the bonding pad section is formed, thereby reducing the electrical power of the lead wire. This eliminates short circuits and bonding problems.

In recent years, as LSIs (large scale integrated circuits) have become more highly integrated and faster, their pellets have become smaller and bonding pads are increasingly placed only on two opposing sides of the pellet. Ta. Conventionally, a laminated ceramic package having bonding pads on only two sides, as shown in FIG. 3, has been used for this type of pellet. In FIG. 3, an LSI Berendro having bonding pads 7a to 7e arranged in a negative row is mounted on the die attach section 1.

In the conventional laminated ceramic package described above, the bonding bands 2a to 2 on the case side adjacent to the lead wires 5 are
It has the disadvantage of short circuiting with e. In FIG. 3 showing a perspective view of the conventional structure and FIG. 4 showing a top view of the conventional structure, bonding bands 7a to 7e on LSL and pellet 6 and bonding bands 2a to 2e on package 8 are connected to lead wires 5 and 5. However, the bonding bands 7a to 7e on the LSI pellet 6 are often concentrated in a part of the corner. Therefore, the bonding pad 7 of the LSI pellet 6
d and the bonding band 2d of the package 8 come into contact with the adjacent bonding pad 2c of the package 8.

This phenomenon is particularly noticeable when the distance between bonding pads 7d to 2d is long. For this reason, a method has recently been devised in which a notch is provided at the tip of the bonding band pattern of the puff cage to avoid electrical short-circuits. However, even in this case, there is a drawback that normal bonding cannot be performed because the lead wire comes into contact with the ceramic part of the lead wire package.
