One embodiment of the present invention relates to a scribe seal integrity detector. In this embodiment a scribe seal integrity detector is formed in an integrated circuit chip die. The scribe seal integrity comprises a scribe seal structure that extends along at least a portion of the periphery of the integrated chip die and a detector test structure. The detector test structure and the scribe seal form an electrical system configured to be accessed for a monitoring of one or more electrical parameters to determine and characterize scribe seal integrity of the integrated circuit chip die. The results of the electric measurements are analyzed for statistically relevant reliability characterization. Other methods and circuits are also disclosed.

摘要:
An embodiment of the invention is a method to reduce light induced corrosion and re-deposition of a metal, 8, (such as copper) that is used to make the interconnect wiring during the semiconductor manufacturing process. The light induced corrosion and re-deposition is caused by the exposure of a P-N junction to light, causing a photovoltaic effect. A photon-blocking layer, 13, is used in the invention to reduce the amount of exposure of the P-N junction to light. The photon blocking layer, 13, of the invention may be a direct band-gap material with a band-gap energy that is less than the lower edge of the energy spectrum of a typical light source used in the semiconductor manufacturing facility (typically less than 1.7 eV).

Disclosed is apparatus and method for decreasing diffusive damage effects to a primary structure (406, 506) within a semiconductor device (400, 500). The device typically comprises a first interconnect (402, 502), and a second interconnect (404, 504). The primary structure is disposed between the first and second interconnects to electrically intercouple them. An active diffusion volume (410, 514) is determined, within which the primary structure is located. A buffer structure (408, 508) is disposed upon the first interconnect in proximity to the primary structure and adapted to buffer the primary via structure from diffusive voiding occurring at a contact point between the primary structure and the first interconnect.
摘要:
Integrated circuit architectures and methods of operation are provided that allow for the connection of a negative back-gate bias voltage to substrate contacts 24, 90, and 56 during burn-in operations. Accordingly, latch up conditions are prevented during burn-in operations when a circuit is especially vulnerable to such conditions and a grounded substrate is provided to allow for the most efficient operation of the circuit during normal conditions.
摘要:
A process for making a semiconductor integrated circuit which has electrodes, contacts and interconnects composed of a multilayer structure including a layer of polycrystalline silicon with an overlying layer of a refractory metal silicide such as MoSi.sub.2 or WSi.sub.2. Adhesion of the metal silicide to the polysilicon is enhanced by forming a thin silicon oxide coating on the polysilicon before sputtering the metal silicide. The resulting structure has low resistance but retains the advantages of polysilicon on silicon.
