    摘要: The present invention discloses a method for preventing electrostatic discharge damages to an article that is made of an insulating material and stored in a container also made of an insulating material by maintaining a minimum safe distance between the article and the top lid of the container such that a saturation electric field cannot be reached at such safety distance and thus electrostatic discharge does not occur. The present invention novel method can be utilized in carrying any insulating articles but is particularly suitable for carrying a quartz reticle in a polycarbonate pod.

    摘要: The preservation of alignment marks and identification marks throughout the multitude of processing steps employed for the manufacture of integrated circuit chips often requires the inclusion of additional operations which impact production cost and product throughput. Current increased utilization of global planarization operations such as chemical-mechanical-polishing have forced the inclusion of additional window opening lithographic steps requiring additional masks and etch operations to keep these marks from being obscured. This invention provides a technique and a reticle design for clearing and preserving alignment and wafer identification marks through planarization and metallization levels with improved throughput and without the need for additional reticles to clear the marks. The alignment mark areas are exposed by a large clear-out window located in the frame area of the contact/via reticle while the wafer identification marks are accommodated in the same fashion by the metal pattern reticle. The lithography for integrated circuit pattern exposure and the window exposure is accomplished by a single stepper pass at each level.

    摘要: The present subject matter relates to a method of stripping a photoresist after the photoresist film has been subjected to a high dose and high energy ion implant process. The method involves soaking the photoresist film in DI water, dry etching with oxygen plasma, and immersing in Caro's acid solution to improve the throughput of removing the film from the underlying substrate. The method can also be used to strip photoresist that has been hardened or altered by other types of processes such as dry etch transfer steps and chemical treatments. In some applications, the dry etching step may be omitted from the stripping process or the dry etching step may be combined with the water soak in an integrated process.

    摘要: An in-line fluid heater including a heater housing that contains a parabolic lamp vessel which houses an infrared lamp. A parabolic reflection vessel in the heater housing is separated from the parabolic lamp vessel by a convex lens. A quartz plate seals the heater housing, and at least one, and typically, multiple leak detectors may be provided in the heater housing. The interior reflective surface of the reflection vessel reflects the heat energy in parallel rays through the quartz plate and to the fluid to be heated. The leak detectors may be connected to an RC circuit which operates a controller to actuate a buzzer or alarm and terminate operation of the heater upon leakage of fluid into the heater housing.

    摘要: A method for manufacturing capacitors is disclosed. The method is applicable to a capacitor whose upper electrode area is smaller than the lower electrode area. It is featured in that a material, such as a TiN hard mask, is inserted between the conventional electrode metal layer and photo resist layer. This enables one to perform the in-situ photo resist layer removal step after dry etching the upper electrode metal. Since the photo resist layer removal step uses oxygen plasma, the surface of the lower electrode polysilicon is formed with a protective oxide layer because the dielectric layer is etched during the process of dry etching the upper electrode metal. Using the disclosed method can solve the corrosion problem on the upper electrode metal and avoid the lower electrode polysilicon from being corroded by the wet etchant.

    摘要: A new method of preventing passivation keyhole damage and resist extrusion using a hydrophillic solvent before photoresist coating is described. Semiconductor device structures are formed in and on a semiconductor substrate and covered by an insulating layer. Metal lines are formed overlying the insulating layer wherein there is a gap between two of the metal lines. A passivation layer is deposited overlying the metal lines wherein the gap is not filled completely by the passivation layer. The passivation layer is coated with a hydrophillic solvent wherein the hydrophillic solvent completely fills the gap. The passivation layer is coated with a photoresist layer which is exposed and developed to form a photoresist mask. The hydrophillic solvent completely filling the gap allows a uniform thickness photoresist layer. The passivation layer is etched away where it is not covered by the photoresist mask where a bonding pad is formed.

    摘要: The present invention discloses a liquid dispensing system and a method for dispensing liquid that includes two hermetically sealed tanks each having a liquid container with a conduit pipe connecting the two containers. A differential pressure exists between the two tanks such that a process liquid can be fed from the second container into a dispensing nozzle under the differential pressure and the gravity of the liquid without the need of a pumping system. The problems of gel formation normally observed in conventional dispensing systems can be eliminated. A high viscosity, short shelf life liquid can be most suitably dispensed by the present invention novel dispensing system and method.
