    Abstract: A method and structure for forming an ink jet print head having a dielectric interstitial layer. A flexible top plate attached to a press can be used to apply pressure to an uncured dielectric interstitial layer. The uncured dielectric interstitial layer is cured while contacting the uncured dielectric interstitial layer with the flexible top plate and applying pressure using the press. Using a flexible top plate rather than a rigid top plate has been found to form a cured interstitial layer over an array of piezoelectric elements which has a more uniform or planar upper surface. An interstitial layer so formed can result in decreased processing time, reduced problems with ink communication in the ink jet print head during use, and decreased manufacturing costs.

  • Patent number: 6969538
    Abstract: The present invention relates to a method for heat processing a substrate. After a coating film is formed on the substrate, the substrate is baked at a predetermined high temperature. The baking step is performed by first increasing the substrate temperature from a predetermined low temperature to a predetermined intermediate temperature that is lower than a predetermined reaction temperature at which the coating film reacts. Next, a second baking step maintains the substrate at the predetermined intermediate temperature for a predetermined period of time, and is followed by a third step of increasing the temperature of the substrate to the predetermined high temperature that is higher than the predetermined reaction temperature. This results in uniform temperature within the surface of the substrate when the temperature of the substrate reaches the reaction temperature. Consequently, a chemical reaction due to heat processing of the coating film within the surface of the substrate is performed uniformly.

  • Patent number: 6599366
    Abstract: The present invention includes a current plate which is arranged above a substrate in a chamber. A pressure inside the chamber is reduced by exhaust means and drying processing is performed on, for example, a coating solution on the substrate. On a peripheral portion of an underneath surface of the current plate, formed is a ring-shaped protrusion corresponding to a peripheral portion of the substrate. A protruding portion of a coating solution at the peripheral portion of the substrate is made flat by air current generated when the pressure is reduced, and consequently a coating film with a uniform film thickness as a whole is formed on the substrate.

  • Patent number: 6589339
    Abstract: Prior to transfer of an wafer W, a mixed gas is being generated and exhausted, thereby fluctuation of concentration and temperature of a solvent component at the beginning of gas introduction into a chamber 3 is suppressed. A step of gelling after the wafer W is carried into an aging unit is divided into several steps. Until a temperature of the wafer W reaches a predetermined treatment temperature, an average concentration of the solvent component in a mixed gas is gradually raised relative to the temperature of the wafer W. Thereby, immediately after the wafer W is transferred into a sealed chamber, the gas of the solvent component is prevented from condensing.

  • Patent number: 6573031
    Abstract: A substrate coated with a coating solution is placed on a heating plate in a processing chamber in which an inert gas is circulating. The substrate is heated on the heating plate while the inert gas is circulating at an extremely small first circulating amount. The substrate is heated further on the heating plate while the inert gas is circulating at a second circulating amount larger than the first circulating amount. Detected is the density of the solvent in the processing chamber. The supply and exhaust amounts of the inert gas are controlled based on the density detected after the start of heating, so that an exhaust amount of the inert gas becomes a predetermined amount for a predetermined period until the solvent density reaches a predetermined density. A necessary control process is performed so that the solvent density reaches the predetermined density when the solvent density has not reached or exceeded the predetermined density after the predetermined period has elapsed.

  • Patent number: 6524389
    Abstract: In a processing chamber for performing heat processing for a substrate, gas for purge, for example, N2 is supplied nearly parallel to the substrate placed on a hot plate with a gap forming member between them and toward both the front and rear faces of the substrate. Thus, an atmosphere around the substrate can be exchanged for the gas for purge efficiently, and moreover the atmosphere around the substrate can be exchanged uniformly. Accordingly, heat processing in a low oxygen atmosphere can be performed in a short time, and moreover the total time required for substrate processing can be shortened. Besides, heat processing in the low oxygen atmosphere can be performed uniformly.

  • Patent number: 6508920
    Abstract: A method for filling recessed microstructures at a surface of a microelectronic workpiece, such as a semiconductor wafer, with metallization is set forth. In accordance with the method, a metal layer is deposited into the microstructures with a process, such as an electroplating process, that generates metal grains that are sufficiently small so as to substantially fill the recessed microstructures. The deposited metal is subsequently subjected to an annealing process at a temperature below about 100 degrees Celsius, and may even take place at ambient room temperature to allow grain growth which provides optimal electrical properties. Various novel apparatus for executing unique annealing processes are also set forth.

  • Patent number: 6391112
    Abstract: A workpiece holding device for a vacuum unit has coolable or heatable transfer plates (2) displaceable independently of one another in a baseplate (1) and each comprising a heat transfer surface (3) which is surrounded by an O-ring (4), is connected to a pipe (5) and, with a workpiece (15) which is pressed against the O-ring (4) by a holder (16), encloses a gap (20). The holder (16) can be locked to the baseplate (1). After lowering of the holder (16) into a closed position and load-free locking to the baseplate (1), the heat transfer plates (2) are pneumatically raised until in each case a stop (23, 22) becomes effective between said heat transfer plates and the holder (16) and determines the width of the gap (20). The gap (20) is then filled via the pipe (5) with a heat transfer medium, e.g. helium. After processing of the workpiece (15), the heat transfer plates (2) are lowered and the holder (16) is released again in a loadfree manner.

  • Patent number: 6372042
    Abstract: A photo process system for semiconductor wafers prevents air from flowing across the top of a baking region to produce a stable downward laminar air flow in front of baking units disposed at several levels in the baking region. The baking region is located on one side of a housing, and a coating unit for coating a wafer with a photoresist is located on the other side of the housing. The housing has a clean air entrance and air filters at an upper portion thereof, and a clean air discharge opening at the very bottom thereof. An air flow containment dam prevents clean air entering the housing from flowing horizontally at the top of the baking region. Such a horizontal flow of air would otherwise produce turbulence severely affecting the ability of the air to flow downward across the front of the baking units and toward the discharge opening as a laminar air flow. The laminar air flow hardly passes into the baking units and thus, hardly induces temperature variations in the coated wafers that are being baked.

  • Patent number: 6261365
    Abstract: When a substrate coated with a coating solution which oxidizes at high temperatures is heat-treated, an oxygen concentration of a treatment atmosphere is lowered when the temperature is low. Next, the substrate is heat-treated in the treatment atmosphere of which the oxygen concentration is lowered. Sequentially, the treatment atmosphere is returned to that with the original oxygen concentration after the passage of a predetermined time after completing the heat treatment. Thereby, the substrate can be heat-treated, with the oxidization of the coating solution being controlled.
