Patent number: 10753841Abstract: A diffusion system to improve the efficiency, accuracy, and consistency of testing the release rate of an active ingredient in semisolid form through a membrane in between a dosage lid and a cell cap mounted on a cell in which a mixer is placed to mix the receptor medium in the cell as the semisolid diffuses through the membrane. The cell can be placed in a heating system to heat the samples. The cell has a sampling arm through which samples of the receptor medium can be extracted without opening the cell cap and dosage lid. The mixer may be cylindrical and may occupy a large surface area of the cell. The mixer may have grooves and other irregularities to increase turbulence while mixing. The system can be automated using an automated sampling and collection station.Type: GrantFiled: August 13, 2018Date of Patent: August 25, 2020Assignee: TELEDYNE INSTRUMENTS, INC.Inventors: Steven W. Shaw, Gary C. Downes

Patent number: 6524463Abstract: A method of processing wafers or other articles within a processing cell, entailing transporting a carrier supporting a vertically-oriented wafer horizontally through an inlet opening of a process cell, processing the vertically-oriented wafer within the process cell, and then transporting the carrier out of the process cell horizontally through an outlet opening of the process cell. In one exemplary implementation, the process performed within the cell is a pre-or post- treatment where the wafer is subjected to an acid solution treatment and/or a rinsing with de-ionized water treatment. In another exemplary implementation, the process performed within the process cell is an electroplating of the plating surface of the wafer. Additionally, a method of processing an empty carrier entailing transporting the carrier horizontally through an inlet opening of a process cell, processing the carrier within the process cell, and transporting the carrier out of the process cell horizontally through an outlet opening.Type: GrantFiled: July 16, 2001Date of Patent: February 25, 2003Assignee: Technic, Inc.Inventors: Daniel J.

Publication number: 20030010625Abstract: A process cell for processing wafers and other planar articles, including a horizontally-transportable carrier for supporting a wafer in a substantially vertical orientation and an enclosure for housing the carrier and performing one or more processes to the wafer. The enclosure including a carrier inlet to allow the horizontal passage of a carrier into the process cell and a carrier outlet to allow the horizontal passage of a carrier to outside of the process cell. One embodiment of a process cell is configured to perform a pre- or post-treatment of a wafer, such as treating the wafer with acid solution and/or with de-ionized water. Another embodiment of the process cell is configured to perform electroplating of the wafer. Another process cell is configured to the process empty carriers, including the striping of undesired plating deposition on cathode contacts.Type: ApplicationFiled: July 16, 2001Publication date: January 16, 2003Inventors: Daniel J.

Patent number: 6419805Abstract: A plating apparatus is disclosed that is particularly useful in improving the plating rate, improving the plating of via holes, improving the uniformity of the plating deposition across the surface of the wafer, and minimizing damage to the wafer. With regard to improving the plating rate and the plating of via holes, the plating apparatus immerses a wafer in a plating fluid bath and continuously directs plating fluid towards the surface of the wafer. Immersing the wafer in a plating fluid bath reduces the occurrence of trapped gas pockets within via holes which makes it easier to plate them. With regard to improving the uniformity of the plating deposition, the plating apparatus and method effectuate random horizontal fluid flow within the bath to reduce the occurrence of relatively long horizontal fluid flow that causes non-uniform plating deposition across the surface of the wafer.Type: GrantFiled: August 15, 2000Date of Patent: July 16, 2002Assignee: Technic Inc.Inventors: Robert Kaufman, Gary C.

Patent number: 6322313Abstract: An apparatus and method for inserting and removing a wafer into and from a plating apparatus, includes an elongated primary arm having a wafer seat for supporting the wafer, an elongated secondary arm for supporting the primary arm, and a mounting surface for supporting the secondary arm. The apparatus further includes a drive band mechanically coupled to the primary arm for causing the movement thereof. The drive band includes a portion wound around a drum that is driven by a motor. The motor, in rotating the drum, causes the drive band to move the primary arm along an axis between a retracted position wherein the primary arm, the secondary arm, and the mounting surface are in a stacked relationship, and an extended position wherein the secondary arm protrudes from the mounting surface along the axis, and the primary arm protrudes from the secondary arm along the axis.Type: GrantFiled: July 6, 2000Date of Patent: November 27, 2001Assignee: Technic Inc.Inventors: Robert Kaufman, Gary C.
