Methods and systems for evaluating checker quality of a verification environment are provided. In some embodiments, an overall sensitivity for the verification environment and an individual sensitivity for a respective checker are calculated. The overall sensitivity is a probability that a plurality of problematic design behaviors, which are propagated to a checker system including at least one checker, can be detected by the verification environment. The individual sensitivity is a probability that a plurality of problematic design behaviors, which are propagated to at least one specific probe among a plurality of probes of a design, can be detected by the checker corresponding to the specific probe. The overall checker sensitivity numbers can show the robustness of the check system. The individual checker sensitivity can guide the user which individual checker or checkers to improve.

It is, accordingly, an object of the present invention to provide a technique which is effective in preventing chips generated during cutting operation on a workpiece from being accumulated in a region ahead in a cutting direction. A representative cutting machine includes a motor, a blade, a body housing having a first region that houses the motor and a second region that covers the blade and projects forward of a front surface of the first region, a base, an angular plate, an outlet formed in the body housing, an opening and a blocking part. The blocking part prevents the air discharged from the outlet from flowing out laterally with respect to the moving direction of the base through a clearance between a front end of the second region and the one end of the angular plate and thereby helps the air discharged from the outlet flow into the opening.

Damascene processing is implemented with dielectric barrier films (50, 90, 91) for improved step coverage and reduced contact resistance. Embodiments include the use of two different dielectric films (50, 31) to avoid misalignment problems. Embodiments further include dual damascene (100A, 100B) processing using Cu metallization (100).
摘要:
An apparatus for measuring the thickness profile and elastic modulus profile of a polishing pad comprise an eddy current sensor and a mechanism to press the eddy current sensor against the polishing pad. The pad thickness is given by the signal of the eddy current sensor. The elastic modulus of the polishing pad is extracted from measurements at different forces applied to the eddy current sensor. The thickness profile and elastic modulus profile of the polishing pad are obtained by scanning the measurement across the whole polishing pad or along a diameter of the polishing pad. The pad thickness profile is used to adjust pad conditioning recipe so that more pad materials is eroded away at thicker area of the pad. By employing the apparatus of present invention, the thickness uniformity of a polishing pad can be better maintained, resulting in longer pad lifetime and better CMP removal rate uniformity.
摘要:
In-laid metallization patterns of copper or a copper alloy are fabricated by a damascene-type process wherein the upper surface of a thick, electroplated copper or copper alloy blanket or overburden layer filling recesses in a substrate surface is subjected to a mask-less, chemically-based differential etching step for partially planarizing/thickness reduction prior to a step of planarization by chemical-mechanical polishing (CMP). The inventive process enables an increase in manufacturing throughput, reduction in cost, and reduction in spent CMP slurry generation.
