Patent number: 9022773Abstract: A device and method for manufacturing integrated circuit packaging using a mold plunger with position compensation in a manufacturing setting. In an embodiment, a compensating mold plunger, which may be used during the manufacture of an integrated circuit package, engages a die set on a carrier and within a bushing. This may be done to inject a mold compound on top of the die/carrier. If the bushing that is housing the die/carrier tandem is misaligned with the plunger in any lateral direction, the amount of pressure may be compromised. A compensating mold plunger includes a flexible portion that allows for the head of the plunger to properly engage the die/carrier despite any possible misalignments. Further, different die/carrier combinations may also be used with a compensating mold plunger because the pressure and force applied may be uniform inside a bushing despite the contents of the bushing.Type: GrantFiled: December 29, 2011Date of Patent: May 5, 2015Assignee: STMicroelectronics, Inc.Inventors: Aaron Cadag, BernieChrisanto Ang, Richard Laylo

Patent number: 7686991Abstract: A method of aligning die and stamping substrate for nano-imprint lithography is described. The method includes aligning the die by linearly displacing the die along a first axis using a first flexure member and pressing the die along a second axis substantially perpendicular to the first axis while maintaining coupling of the die with the first flexure member.Type: GrantFiled: April 18, 2007Date of Patent: March 30, 2010Assignee: WD Media, Inc.Inventor: Bruce M. Harper

Patent number: 7686606Abstract: An imprint embossing alignment system. In one embodiment, the system includes a die having a bottom surface, an embossing foil positioned above the bottom surface, and a mandrel, to receive the substrate, having a rod portion that extends through a central portion of the die. The system also includes a ball bushing positioned around the rod portion and a ring portion positioned between the ball bushing and the embossing foil to hold a precise alignment of a centerline of the rod portion and a centerline of the embossing foil.Type: GrantFiled: January 20, 2004Date of Patent: March 30, 2010Assignee: WD Media, Inc.Inventors: Bruce M. Harper, Toshiyuki Max Saito

Patent number: 7594808Abstract: A mold for molding a product in a cavity formed by closing the mold includes a first half; a second half; and a plurality of aligning members which come in contact with each side circumferential surface of the first half 100 and the second half at least in three directions, when the mold is closed. After the mold is closed, at least one of the aligning members is moved to contact the aligning member with the each side circumferential surface of the first half and the second half, which enables a center axis alignment between the first half and the second half.Type: GrantFiled: January 9, 2007Date of Patent: September 29, 2009Assignee: FUJIFILM CorporationInventors: Noriko Eiha, Seiichi Watanabe, Yasuhito Hiraki

Patent number: 7591642Abstract: A mold for an optical component is provided in which a first tapered surface is provided in a first mold while a second tapered surface is provided in a second mold. In the mold for the optical component, a curved surface distance which is a distance between a first mold curved surface and a second mold curved surface is greater than a lens thickness which is a distance between a first lens surface and a second lens surface in a state where the second tapered surface is contact with the first tapered surface. Moreover, the second tapered surface moves to a position where the curved surface distance is equal to the lens thickness, to elastically transform the first mold and fit onto the first tapered surface.Type: GrantFiled: March 8, 2007Date of Patent: September 22, 2009Assignees: FUJIFILM Corporation, Fujinon CorporationInventors: Tatsuhiko Saeki, Masanori Utsugi

Patent number: 7455510Abstract: A method and apparatus are provided for forming a sheet of polymeric material, such as polycarbonate. A forming mold is provided having halves that engage for forming a heated sheet therebetween. Each of the halves defines an interior cavity having a peripheral edge. The sheet is retained between the peripheral edges of the halves and a vacuum is generated within one of the cavities for drawing the sheet therein, whereby a sensing mechanism detects a draw depth for initiating a cooling mechanism to cool the sheet to a temperature below a glass transition temperature of the material. A series of retention mechanisms are provided about the peripheral edge of one of the halves, for biasing the sheet into engagement with the peripheral edge of the opposing half. A trimming mechanism is further provided for trimming the perimeter of the sheet to a desired form.Type: GrantFiled: April 13, 2007Date of Patent: November 25, 2008Inventors: Edwin J. Oakey, Rodney M. Tinney

Patent number: 7329114Abstract: Isothermal imprint embossing system. In one embodiment, the system includes a heater to pre-heat a disk substrate to an embossing temperature, a die assembly with an embossing foil to imprint the embossable film disposed on the disk substrate, and a heat tunnel disposed between the heater and the die assembly to maintain the embossing temperature.Type: GrantFiled: January 20, 2004Date of Patent: February 12, 2008Assignee: Komag, Inc.Inventors: Bruce M. Harper, Toshiyuki Max Saito, Christopher H. Bajorek
