摘要:
A semiconductor device includes a first protection film for covering a first metal wiring. A second protection film is disposed on the first protection film, which is covered with a solder layer. Even if a crack is generated in the second protection film before the solder layer is formed on the second protection film, the crack is restricted from proceeding into the first protection film.

A formation method of a metallic electrode of a semiconductor device is disclosed. The method includes: acquiring data about surface shape of a surface part of a semiconductor substrate; and causing a deformation device to deform the semiconductor substrate based on the data so that a distance between a cutting plane and the surface part falls within a required accuracy in cutting amount. In deforming the semiconductor substrate, multiple actuators are used as the deformation device. A pitch of the multiple actuators is set to a value that is greater than one-half of wavelength of spatial frequency of a thickness distribution of the semiconductor substrate and that is less than or equal to the wavelength.

In a method of manufacturing a semiconductor device, an electrode layer is formed on a surface of a semiconductor substrate, and a resin insulation layer is formed on the surface of the semiconductor substrate so that the electrode layer can be covered with the resin insulation layer. A tapered hole is formed in the insulation layer by using a tool bit having a rake angle of zero or a negative value. The tapered hole has an opening defined by the insulation layer, a bottom defined by the electrode layer, and a side wall connecting the opening to the bottom.

摘要:
A method for manufacturing a semiconductor device having on a silicon substrate semiconductor elements and aluminum (Al) alloy wiring leads as electrically connected thereto is disclosed. The method includes the steps of forming on the silicon substrate an Al alloy layer containing therein copper (Cu), and forming on the Al alloy layer a titanium nitride (TiN) film with enhanced chemical reactivity by using sputtering techniques while applying thereto a DC power of 5.5 W/cm2 or less. Fabrication of such reactivity-rich TiN film on the Al alloy layer results in a reaction layer of Al and Ti being subdivided into several spaced-apart segments. In this case, the reaction layer hardly serves as any diffusion path; thus, it becomes possible to prevent Cu as contained in the Al alloy layer from attempting to outdiffuse with the reaction layer being as its diffusion path. This makes it possible to suppress or minimize unwanted fabrication of AlN on or above the surface of an Al containing lead pattern, thereby enabling increase in electromigration (EM) lifetime of electrical interconnect leads used.
