摘要:
A reliability evaluation test apparatus (10) of this invention includes a wafer storage section (12) which stores a wafer (W) in a state wherein the electrode pads of a number of devices formed on the wafer and the bumps of a contactor (11) are totally in electrical contact with each other. The wafer storage section (12) transmits/receives a test signal to/from a measurement section (15) and has a hermetic and heat insulating structure. The wafer storage section (12) has a pressure mechanism (13) which presses the contactor (11) and a heating mechanism (14) which directly heats the wafer (W) totally in contact with the contactor (11) to a predetermined high temperature. The reliability of an interconnection film and insulating film formed on the semiconductor wafer are evaluated under an accelerated condition.
摘要:
A reliability tester (10) comprises a wafer containing section (12) containing a wafer (W) in the state that electrode pads of many devices formed on the wafer are all in electrical contact with bumps of a contactor (11). This wafer containing section (12) transmits/receives test signals with a measuring section (15) and has a hermetic and heat-insulating structure. The wafer containing section (12) has a pressing mechanism (13) for pressing the contactor (11) and a heating mechanism (14) for directly heating the wafer (W) in all contact with the contactor (11) to a predetermined high temperature. Thus, this tester evaluates the reliability of a wiring film and that of an insulation film formed on the semiconductor wafer under an acceleration condition.

摘要:
An oxide film such as native oxide film can be etched by forming a haloid or a liquid containing hydrogen halide, which is produced by a gas reaction such as one between a halogen-containing gas and a basic gas, on the oxide film. The etching proceeds mainly in a chemical reaction. So, the excellent etching selectivity of the oxide film with respect to underlying substrate is obtained, and the substrate receives no damage by the etching. Furthermore, the etching can be carried out before processes such as etching, deposition, oxidation, diffusion, or epitaxial growth are carried out to the substrate. The processed layer formed on the substrate, therefore, does not contain any useless native oxide.

There is provided a semiconductor device in which redundancy fuses (16, 17) formed in an upper layer wiring region can be cut without damaging an underlying Si substrate (11) or adjacent regions. The semiconductor device comprises a lower layer wiring (13) formed within an interlayer insulating film (12) on the Si substrate (11), and an upper layer metal wiring (15) made of Al, Cu or the like, formed above the lower layer wiring (13) and connected thereto through a via metal (14), wherein the redundancy fuses (16, 17) are formed in the same wiring layer as the upper layer metal wiring (15). For cutting a fuse (16) by irradiating with a laser having a wavelength in a range of 1,000 to 1,100 nm and a beam diameter D ( µm), the fuse (16) may be designed to have a film thickness T ( µm) and a width W ( µm) which satisfy T ≦ (-0.15 (D+2σ) +0.46) exp (2W), where σ ( µm) is an alignment accuracy of the center of the laser beam to the center of the fuse (16), with the result that the fuse (16) formed in the same wiring layer as the upper layer metal wiring (15) can be cut without damaging the Si substrate (11), an adjacent fuse (17) and the upper layer metal wiring (15).
