Patent number: 6446646Abstract: Chambers each include an inlet port for supplying N2 gas and an outlet port for discharging an inner atmosphere, and therefore the chambers have different amounts of supply of N2 gas in a unit of time and different amounts of discharge of inner atmosphere in a unit of time. With this structure, the first to fourth processing chambers are controlled to have the lowest inner pressure(p3), a transfer module is controlled to have an inner pressure (p2) higher than the inner pressure (p3) and a loader and an unloader are controlled to have the highest inner pressure (p1). That eliminates the necessity for keeping the whole substrate processing apparatus at the highest inner pressure (p1) and supplying a large amount of N2 gas, and therefore it is possible to achieve processings of substrate at lower cost, with shorter purge time and less contamination of substrate.Type: GrantFiled: May 29, 1998Date of Patent: September 10, 2002Assignee: Dainippon Screen Mfg.

Publication number: 20010047814Abstract: A wash tank has a conveyor belt traversing through a sterilizing wash bath. Fruit is loaded into the wash tank by way of an inclined ramp having a swinging barrier at the end thereof. The conveyor belt has rows of chevron shaped fingers extending generally transversely therefrom. The fingers extend through slots in the ramp to push the fruit through the swinging barrier and into a cage. The conveyor belt and fingers pass through the cage, which cage has a top and sides.

Patent number: 4974619Abstract: There is disclosed a cleaning device for cleaning a semiconductor wafer. According to the present invention, ech of the steps of the cleaning process used a separate carrier, so that none but the wafers need be washed, saving washing time. When drying, the surfaces of the wafers are kept from being contaminated by residual cleansers, thereby improving the yield rate.Type: GrantFiled: February 3, 1989Date of Patent: December 4, 1990Assignee: SamSung Electronics Co., Ltd.Inventor: Jung-Sik Yu

Patent number: 4850381Abstract: Apparatus for stripping photoresist and other coatings from integrated circuit wafers comprises a series of vertically positioned casings with rotary turrets within each casing each accommodating approximately 10 wafers. Wafers are received in conventional "boats", lifted one at a time and inserted in a pocket in the first turret. The turret indexes intermittently, immersing the wafer in solvent until it travels almost a full 360.degree.; the wafer is then lifted from the first turret and inserted in a second turret which immerses the wafer during another almost 360.degree. travel in additional solvent. Toward the end of travel in the second turret a spray nozzle strips all remaining photoresist from the wafer. The wafer is then lifted from the second turret and inserted in a first pocket, optionally containing alcohol.Type: GrantFiled: February 1, 1988Date of Patent: July 25, 1989Assignee: Rolf MoeInventors: Rolf Moe, David J. Corriea, John E. Premeau

Patent number: 4834123Abstract: A bottle washer removing bottles from a conveyor, rotating them about 360 degrees, and using paddles of extended length and a stationary guide to replace the bottles on the conveyor. The washer may sit over the conveyor transporting the bottles. The conveyor moves the bottles between paddles which will rotate them through a circle of 360 degrees. At the very end of that arc, however, an obstructing guide rail directs the bottles out of the rotational plane to avoid their colliding with the entering bottles. The paddles that move the bottles about the arc have extensions lying in the direction that the conveyor moves. These extensions control the motion of the bottles as they move out of their plane of rotation so that they will return to the conveyor. The bottle washer, to work at greater length upon the bottles, may in fact move the bottles about two circles of approximately 360 degrees each. As the bottles complete the first rotation, the obstructing guide moves them out of the plane of the first rotation.Type: GrantFiled: October 6, 1987Date of Patent: May 30, 1989Inventor: William J. McBrady

Patent number: 4816081Abstract: A process for drying semiconductor wafers or similar substrates maintains the substrates in a static position to avoid the generation of undesired particulate. The substrates are maintained within the apparatus at an angle of approximately 30.degree. from the vertical to facilitate complete drainage of the processing fluid. According to this invention, the substrates are positioned in the chamber of the apparatus at the appropriate angle, the chamber is closed in a fluid tight seal and filled with the processing fluid, until the fluid overflows through a vacuum valve. While maintaining the chamber completely filled, vacuum aspiration is continued to degas the chamber. While continuing vacuum aspiration of the chamber, a vacuum assisted drain valve is opened, and clean dry inert gas is introduced above the draining fluid. The draining step assures that any droplets remain with the draining fluid so that the substrates emerge dry as the fluid drains away.Type: GrantFiled: February 17, 1987Date of Patent: March 28, 1989Assignee: FSI CorporationInventors: Jitesh R. Mehta, Don C. Burkman, Cooky Mezaki

Patent number: 4736759Abstract: Apparatus and a method for cleaning, rinsing and drying substrates, such as semiconductor wafers. The apparatus has a cleaning tank in which one or more megasonic transducers are located, the transducers being adapted to direct megasonic energy past the substrates for cleaning the same. The substrates are held in the cleaning tank by an improved holder which can be pivoted from one side to the other to present opposite side margins of the substrates to the megasonic energy field when otherwise such opposite side margins would not be exposed to such energy field due to the blocking action of parts of the holder. A rinse tank for containing a rinse solution is adjacent to the cleaning tank, and a robotic transfer arm mechanism moves the substrates in the holder from the cleaning tank to the rinse tank for immersion of the substrates into the rinse solution which can be heated to an elevated temperature or can be at ambient temperature.Type: GrantFiled: April 24, 1987Date of Patent: April 12, 1988Assignee: Robert A. CoberlyInventors: Robert A. Coberly, Mark J. Beck, Dan S. Azlin, Karl J. Gifford

Patent number: 4724854Abstract: An apparatus is disclosed for pre-washing and accumulating eggs which includes within a pre-wash station a pre-wash housing as well as spray conduits and spray jets for receiving pressurized cleaning fluid from a pump for spraying upon eggs traveling upon a conveyor located therebelow. A holding tank receives the spent fluid for recirculation through the pump. An egg diverting mechanism is included to prevent the grouping of eggs upon one lateral location upon the conveyor. The diverting mechanism includes rods extending laterally across the conveyor and one or more vertically extending plates positioned immediately above the conveyor to divert or guide the eggs into a somewhat more random orientation upon the egg conveyor when they reach the diverting mechanism in a group or bunched configuration. An accumulator is included to divide the randomly positioned eggs into rows upon the conveyor.Type: GrantFiled: April 7, 1986Date of Patent: February 16, 1988Inventor: Henry Y. Kuhl

Patent number: 4688586Abstract: In a conveying apparatus for castings in a cleaning device, there are tooth-type casting holders which rotate about a horizontal or slightly inclined axis and comprise two gripping parts of which the upper part serves as a tension member for tensioning the casting piece, while the lower stationary gripping part is comprised of two or more supports for the casting that promote the cleaning operation by means of a revolving movement. The supports are positioned at an angle to the axis of rotation and are spaced by substantially equal distances at both sides. These supports hold the casting in a corresponding angular position relative to the axis of rotation. The upper gripping part can comprise one or more pendulously supported beams which, in the tensioning position, transmit tensioning or securing forces to the casting.Type: GrantFiled: February 24, 1984Date of Patent: August 25, 1987Assignee: BMD Badische Maschinenfabrik Durlach GmbHInventors: Martin Weis, Adolf Scholz
