摘要:
The present invention can realize a highly-integrated semiconductor device having a MONOS type nonvolatile memory cell equipped with a split gate structure without deteriorating the reliability of the device. A memory gate electrode of a memory nMIS has a height greater by from 20 to 100 nm than that of a select gate electrode of a select nMIS so that the width of a sidewall formed over one (side surface on the side of a source region) of the side surfaces of the memory gate electrode is adjusted to a width necessary for achieving desired disturb characteristics. In addition, a gate electrode of a peripheral second nMIS has a height not greater than the height of a select gate electrode of a select nMIS to reduce the width of a sidewall formed over the side surface of the gate electrode of the peripheral second nMIS so that a shared contact hole is prevented from being filled with the sidewall.

Provided is a technique capable of improving the reliability of a semiconductor device having a slit made over a main surface of a semiconductor substrate, so as to surround each element formation region. In the technique, a second passivation film covers the side surface of an opening made to make the upper surface of a sixth-layer interconnection M6 used for bonding pads naked, and the inner walls (the side surfaces and the bottom surface) of a slit made to surround the circumference of a guard ring and made in a first passivation film, an insulating film for bonding, and an interlayer dielectric, so as to cause the bottom thereof not to penetrate through a barrier insulating film.
摘要:
In the current manufacturing process of LSI, or semiconductor integrated circuit device, the step of assembling device (such as resin sealing step) is normally followed by the voltage-application test (high-temperature and high-humidity test) in an environment of high temperature (such as an approximate range from 85 to 130° C.) and high humidity (such as about 80% RH). For that test, the inventors of the present invention found the phenomenon of occurrence of separation of titanium nitride film as the anti-reflection film from upper film and of generation of cracks in the titanium nitride film at an edge part of upper surface of the aluminum-based bonding pad applied with a positive voltage during the high-temperature and high-humidity test caused by an electrochemical reaction due to moisture incoming through the sealing resin and the like to generate oxidation and bulging of the titanium nitride film. An invention of the present application is to remove the titanium nitride film over the pad in a ring or slit shape at peripheral area of the aluminum-based bonding pad.

The interface between two nonmagnetic fluids, typically liquid layers, in contact with each other is changed by applying a magnetic field thereto. The interface is raised or depressed into an upward or downward convex shape.

In manufacturing an LSI, or semiconductor integrated circuit device, the step of assembling device (such as resin sealing step) is normally followed by a voltage-application test in an environment of high temperature (e.g., from 85 to 130° C.) and high humidity (e.g., about 80% RH). It has been found that separation of a titanium nitride anti-reflection film from an upper film and generation of cracks in the titanium nitride film at an upper surface edge part of the aluminum-based bonding pad applied with a positive voltage in the test is caused by an electrochemical reaction due to moisture incoming through the sealing resin and the like to generate oxidation and bulging of the titanium nitride film. These problems are addressed by removing the titanium nitride film over the pad in a ring or slit shape at peripheral area of the aluminum-based bonding pad.
摘要:
To provide: a technique capable of suppressing a titanium nitride film that is exposed at the side surface of an opening from turning into a titanium oxide film even when water permeates the opening over a pad from outside a semiconductor device and thus improving the reliability of the semiconductor device; and a technique capable of suppressing a crack from occurring in a surface protective film of a pad and improving the reliability of a semiconductor device. An opening is formed so that the diameter of the opening is smaller than the diameter of another opening and the opening is included in the other opening. Due to this, it is possible to cover the side surface of an antireflection film that is exposed at the side surface of the other opening with a surface protective film in which the opening is formed. As a result of this, it is possible to form a pad without exposing the side surface of the antireflection film.
