Patent number: 7293906Abstract: An apparatus having a light source, a reflector, and a light pipe is disclosed. The light source includes a plurality of LED dies arranged in an array along a first direction, each LED die emitting light in a second direction. The light pipe includes a layer of transparent material having a top surface, a bottom surface, and an edge surface. The reflector reflects light from the LED dies traveling in the second direction into the edge surface of the light pipe such that a portion of the light is reflected by the top and bottom surfaces of the reflector. In one embodiment, the reflector redirects light leaving the LED dies within a predetermined cone of angles about the first direction into the light pipe such that the light in that predetermined cone of angles is totally reflected by the top surface of the light pipe.Type: GrantFiled: May 23, 2005Date of Patent: November 13, 2007Assignee: Avago Technologies ECBU IP (Singapore) Pte LtdInventors: Thye Linn Mok, Siew Kim Tan

Patent number: 7288366Abstract: A reticle structure and a method of forming a photoresist profile on a substrate using the reticle having a multi-level profile. The reticle comprises (1) a transparent substrate, (2) a partially transmitting 180 degree phase shift film overlying predetermined areas of the transparent substrate to transmit approximately 20 to 70% of incident light, and (3) an opaque film overlying the predetermined areas of the partially transmitting 180 degree phase shift film. The method comprises the following steps: a) depositing a photoresist film over the substrate; b) directing light to the photoresist film through the reticle, and c) developing the photoresist film to form an opening in the resist layer where light only passed thru the substrate, and to remove intermediate thickness of the photoresist film, in the areas where the light passed through the partially transmitting 180 degree phase shift film. In an aspect, the photoresist film is comprised of a lower photoresist layer and an upper photoresist layer.Type: GrantFiled: October 24, 2003Date of Patent: October 30, 2007Assignee: Chartered Semiconductor Manufacturing Ltd.Inventors: Sia Kim Tan, Qun Ying Lin, Soon Yoeng Tan, Huey Ming Chong

Publication number: 20070210827Abstract: Providing ASIC equivalents of FPGAs is facilitated and made more efficient and economical by using an ASIC architecture including a plurality of so-called hybrid logic elements (“HLEs”), each of which can provide a portion of the full functionality of an FPGA logic element (“LE”). The functionality of each FPGA LE implementing a user's logic design can be mapped to one or more HLEs without re-synthesis of the user's logic. Only as many HLEs as are necessary are used to perform the functions of each LE. The one-for-one equivalence between each LE and either (1) one HLE or (2) a group of HLEs facilitates mapping (without re-synthesis) in either direction between FPGA and ASIC designs.Type: ApplicationFiled: May 7, 2007Publication date: September 13, 2007Inventors: Kar Chua, Sammy Cheung, Hee Phoon, Kim Tan, Wei Goay

Publication number: 20070085972Abstract: The invention relates to a method of electronic contrast enhancement for an LCD panel for use in an imaging device. The method comprises the step of coupling the LCD panel with a trim retarder in a pre-determined azimuthal orientation for at least partially compensating the residual in-plane retardance, followed by the step of non-mechanical fine-tuning of a dark state of the LCD panel. In the preferred embodiment, the fine-tuning of the dark state of the LCD panel is realized by adjusting the dark-state magnitude of the LC voltage. The method can be used in batch, e.g. wafer-level manufacturing of integrated trim retarder/LCD panels assemblies that can be electronically tuned to provide high on/off contrast.Type: ApplicationFiled: October 17, 2006Publication date: April 19, 2007Applicant: JDS Uniphase CorporationInventors: Kim TAN, Andrew Taylor, Apurba Pradhan

Publication number: 20070031996Abstract: An integrated circuit is packaged, in one embodiment, by wire bonding to pads supported by tape. The tape also supports traces that run from the wire bonded location to a pad for solder balls. A heat spreader is thermally connected to the integrated circuit and is located not just in the area under the die but also extends to the edge of the package in the area outside the wire bonding location. This outer area is thermally connected to the area under the die by thermal bars that run between some of the wire bond locations. During the manufacturing of the package the heat spreader is connected to slotted rails by tie bars. During singulation, the tie bars are easily broken or sawed because they are significantly reduced in thickness from the thickness of the heat spreader as a whole.Type: ApplicationFiled: April 16, 2004Publication date: February 8, 2007Inventors: Sheila Chopin, Peter Harper, Jose Montes De Oca, Kim Tan, Lan Han

Publication number: 20060268207Abstract: A C-plate compensator is disclosed for compensating the residual A-plate and C-plate retardance of a reflective liquid crystal on silicon (LCoS) display or a transmissive liquid crystal (LC) display in a projection display system. The C-plate incorporates a form-birefringent coating, whose retardance magnitude can be adjusted by tilting with respect to the display panel (X-Y) plane.
