A packaged integrated circuit device with a multi-level leadframe has a plurality of integral capacitors formed by placing a thin dielectric layer between a lower leadframe and an upper leadframe, one of the leadframes being subdivided into a plurality of portions, each subdivided portion with an accessible tab for wire attachment. The planar capacitors are bonded to the bottom surface of the semiconductor chip and act as a die support paddle. Each capacitor may be configured to provide the desired voltage decoupling and noise suppression for a particular portion of the integrated circuit to which it is connected. Capacitors useful for other purposes may be likewise provided in the package.

A plastic-molded semiconductor device comprises a semiconductor pellet having an insulating substrate and an integrated circuit formed on the insulating substrate, and a pellet mounting member on which the semiconductor pellet is mounted. The pellet mounting member is not provided with any conductive portion at least under the center of the insulating substrate. The distance between the interconnection layer of the integrated circuit and the conductive portion of the pellet mounting member is relatively long, so the semiconductor device has a small parasitic capacitance. This results in a high speed and a low power dissipation.

In a plastic molded semiconductor device in which inner leads overlap a semiconductor chip in a molded plastic body, the width of the chip may be close to the width of the plastic body without a decrease in the high resistance of the inner leads to the pull out thereof from the plastic body, and the layout of the inner leads may be unrestricted since the inner leads may occupy the region above the chip.

A package (10) for very large scale integrated circuit (VLSI) includes an electrically and thermally conductive tagboard (20) carrying the chip (12); supply terminals (15a) receiving a first supply potential; an interconnect structure (16) made of ceramic which surrounds the chip (12) and carries both the signal terminals (14) of the package (10) and the supply terminals (15b) receiving a second supply potential, the interconnect structure (16) incorporating the signal and supply conductors intended for the chip (12); and a decoupling device (17) including capacitors (19) and two conductor faces (18a, 18b) connected respectively to the supply terminals (15a, 15b). The decoupling by the capicitors (19) is thus done as close as possible to the conductor faces (18a and 18b) and as close as possible to the chip (12) at the level of islets (32a, 32b).

A MOSFET device is formed on a P- doped semiconductor substrate with an N- well formed therein, with a pair of isolation regions formed in the N- well with a gate oxide layer formed above the N- well. An FET device is formed with source and drain regions within the N-well, and a gate electrode formed above the gate oxide layer aligned with the source and drain regions. The gate electrode comprises a stack of layers. A polysilicon layer is formed on the gate oxide layer. A tungsten nitride dopant barrier layer is formed upon the polysilicon layer having a thickness of from about 5 nm to about 20 nm, and a tungsten silicide layer is formed upon the tungsten nitride layer.
