摘要:
A method and a measurement system to provide an in situ measurement of the thickness of a layer deposited on a substrate is described. The measurement system includes the optical sensor integrated into a movable element hovering over the substrate in close proximity to the layer. The optical sensor element is adapted to emit and detect optical signals. The measurement system provides an optical, and thus contactless approach to determine the thickness of the layer during the growth of the layer. The inventive measurement system is particularly suited for an electroplating system and process.

A system (and method) for real-time measurement of trace metal concentration in a chemical mechanical polishing (CMP) slurry, includes an electromagnetic radiation flow cell carrying a CMP slurry, a slurry pickup head coupled to the flow cell, and an analyzer for measuring properties of the slurry flowing through the flow cell.
摘要:
An apparatus for conducting heat from a computer component to a heat sink. The invention may include a thermal interface material (TIM). The invention may further include a seal or gasket that at least partially encloses the TIM. The gasket may facilitate retaining the TIM within its sidewall, and thus in place on or near a computer component. Generally, the gasket may be placed between the computer component (or a silicon board or other material upon which the computer component is located) and a heat sink. An insert may be placed within the gasket and define an aperture. The chip seats in the aperture and thus is spatially located with respect to the insert. The TIM abuts both the computer component and a heat sink. A desiccant may be located within the gasket and absorb any moisture diffusing or migrating through the gasket.

A method (and system) for non-destructive measurement of a depth of a feature in a structure, includes using a scanning electron microscope (SEM) image to navigate to find the feature in an X-ray image, using an electron beam to produce a fluorescent emission in the feature, and using an X-ray count made at a position of the feature in the X-ray image, to determine a depth of the feature.

A method and a package for circuit chip package having a bent structure. The circuit chip package includes: a substrate having a first coefficient of thermal expansion (CTE); a circuit chip, having a second CTE, mounted onto the substrate; a metal foil disposed on the circuit chip in thermal contact with the chip; a metal lid having (i) a third CTE that is different from the first CTE and (ii) a bottom edge region, where the metal lid is disposed on the metal foil in thermal contact with the metal foil; and an adhesive layer along the bottom edge of the metal lid, cured at a first temperature, bonding the lid to the substrate, producing an assembly which, at a second temperature, is transformed to a bent circuit chip package.
