Title: Apparatus and methods for drying batches of disks
Inventor: JONES OLIVER DAVID
IPC: H01L21/677
Filed: 2000-05-29
Granted: 2001-09-11
Abstract: Liquid is removed from batches of substrates by apparatus and methods for drying substrates that have been wet in an elongated liquid bath. The substrates are moved relative to the bath and an elongated gas-filled volume at rates of movement selected according to the location of the batches of substrates in the bath or the volume. As an example, the substrates and the bath are separated at a controlled rate to form a thin layer of liquid on each substrate as each substrate enters the gas-filled volume. The gas-filled volume is defined by an elongated hot chamber and hot gas directed into the volume and across the substrates and out of the volume continuously transfers thermal energy to the substrates. The flow rate of the gas into the volume is related to introduction of the substrates into the bath to avoid disturbing the liquid in the bath. The thermal energy transferred to the substrates in the volume evaporates the thin layer from the substrates without decreasing the rate of separation of the substrates and the bath below the maximum rate of such separation at which a meniscus will form between the bath and the surface of one of the substrates during such separation. Relative humidity in the volume is controlled by sensing the relative humidity and regulating the speed of a fan that draws gas from the volume.

Title: System and method for improving energy purity and implant consistency, and for minimizing charge accumulation of an implanted substrate
Inventor: KELLERMAN PETER LAWRENCE
IPC: H01J37/32
Filed: 2000-08-04
Granted: 2001-11-21
Abstract: A plasma immersion ion implantation method and system is provided for maintaining uniformity in implant energy distribution and for minimizing charge accumulation of an implanted substrate such as a wafer. A voltage modulator (27) applies a pulsed voltage signal (-Vp) to a platen (14) in a process chamber (17) containing a plasma, so that ions in the plasma are attracted by and implanted into a wafer residing on the platen. The voltage modulator (27) comprises: (i) a first switch (50) disposed between a power supply (48) and the platen for momentarily establishing a connection therebetween and supplying the pulsed voltage signal to the platen; (ii) a second switch (54) disposed between the platen (14) and ground for at least momentarily closing to discharge residual voltage (-Vr) from the platen after the first switch (50) opens and the connection between the power supply and the platen is broken; and (iii) a controller (56) for controlling sequential operation of the switches (50, 54). By closing second switch (54) and grounding the platen, (a) only ions within a certain energy level range are implanted into the wafer, improving the implant energy distribution, and (b) wafer charging due to implantation of positive ions is neutralized by allowing electrons in the plasma to flow toward the wafer between implant pulses. Upon opening, second switch (54) permits the platen to float to achieve the floating potential of the plasma thus minimizing voltage stresses on devices in the wafer. Alternatively, the platen may be positively biased to the plasma floating potential.

Granted: 2002-10-11
Abstract: The present invention relates to an optical disk drive that performs recording power calibration, in which recording is carried out in predetermined test areas on an optical disk by varying recording power, and optimum recording power is determined based on characteristic values obtained from reproduction signals of the predetermined test areas. This optical disk drive includes: a mean value calculating unit that performs recording in a plurality of test areas by varying the recording power, and then calculates the mean value of a plurality of characteristic values obtained from reproduction signals of the test areas; and an optimum recording power setting unit that sets optimum recording power based on the mean value of the characteristic values calculated by the mean value calculating unit. With this optical disk drive, adverse influence of the periodic fluctuation of an optical disk can be reduced by virtue of the mean value of the characteristic values obtained from the test areas having different angle positions on the optical disk. Thus, the optimum recording power can be set with high precision.

Title: Symmetrical package for semiconductor die
Inventor: LAM ALLEN K
IPC: H01L23/495
Filed: 2000-08-19
Granted: 2003-01-01
Abstract: A semiconductor package contains a plurality of sheet metal leads that are attached to one or more terminals on a top side of a semiconductor die. A heat sink is attached to a terminal on a bottom side of the die. Each of the leads extends across the die and beyond opposite edges of the die and is symmetrical about an axis of the die. At the locations where the leads pass over the edges of the die notches are formed on the sides of the leads which face the die, thereby assuring that there is no contact between the leads and the peripheral portion of the top surface of the die. Particularly in power MOSFETs the peripheral portion of the top surface normally contains an equipotential ring which is directly connected to the backside (drain) of the MOSFET, and hence a short between the leads on the top of the die and the equipotential ring would destroy the device. The result is a package that is extremely rugged and that is symmetrical about the axis of the die. To avoid shorting between adjacent leads, moats are formed in the leads where they face the die to prevent liquid epoxy or solder from spreading between the leads. Since no central tie bar is required, multiple dice can readily be packaged in a single plastic capsule.

Granted: 2003-08-21
Abstract: A method and apparatus for reducing voice latency in a voice-over-data wireless communication system. In a transmitter, data frames are created from audio information by a vocoder and stored in a queue. Prior to storage, some of the data frames are eliminated, or dropped, and are not stored in the queue. In a receiver, data frames are generated from received signals and stored in a queue. Prior to storage in the receiver queue, some of the data frames are dropped. Data frames are dropped either at a single fixed rate, a dual fixed rate, or a variable rate, generally depending on a communication channel latency. By dropping data frames at the transmitter, the receiver, or both, voice latency due to data frame retransmissions is reduced.

Title: Contaminant processing system for an acoustic touchscreen
Inventor: ARMSTRONG DONALD B
IPC: G06F3/033
Filed: 2000-10-13
Granted: 2002-10-21
Abstract: A method for minimizing the shadowing effects of a contaminant on a surface acoustic wave touchscreen is provided. The disclosed system compares the measured waveform against a baseline waveform for each axis and validates the new touch if the measured waveform is different from the baseline waveform for either axis. As a consequence of this approach, even if the new touch lies within the shadow created by a contaminant in one axis, the new touch is still validated as it is not within the shadow created by the contaminant in the second axis. In one embodiment, after the system determines that the measured response is different from the baseline in at least one axis, the system compares the new touch to one or more selection criteria to insure that it is a valid touch and not due to a contaminant, electrical noise, or other improper source. Preferably the duration of the new touch is monitored, thus allowing the new touch to be invalidated if the duration is too short, indicating system noise, or too long, indicating for example, a contaminant. Also preferably the size of the new touch is determined, thus allowing the touch to be invalidated if the size is too large which may be indicative of a contaminant or other foreign body resting on the touchscreen surface.

Title: Recirculating shade tree blender for a graphics system
Inventor: DREBIN ROBERT A
IPC: G06T15/00
Filed: 2001-08-23
Granted: 2005-11-21
Abstract: A graphics system including a custom graphics and audio processor produces exciting 2D and 3D graphics and surround sound. The system includes a graphics and audio processor including a 3D graphics pipeline and an audio digital signal processor. To achieve multi-texturing, conventional graphics rendering systems typically rely on multiple rendering passes or require multiple serial/parallel texture-retrieval/processing circuits which occupy additional chip real-estate and exacerbate memory arbitration problems. To solve this problem and to provide an enhanced repertoire of multi-texturing capabilities, a relatively low chip-footprint, versatile texture environment (TEV) processing subsystem is implemented in a pipelined graphics system by utilizing a flexible API and a hardware-accelerated programmable texture blender/shader arrangement that circulates computed color and alpha data over multiple texture blending/shading cycles (stages). The texture-environment subsystem combines per-vertex lighting, textures and constant (rasterized) colors to form computed pixel color prior to fogging and final pixel blending. Blending operations for color (RGB) and alpha components are independently processed within the TEV subsystem by a single sub-blend unit consisting of a set of color/alpha-combiner (shader) hardware that is reused over multiple processing stages co combine multiple textures. A set of four selectable current-color input/output registers which are shared among all stages is provided ac the output of the sub-blend unit to temporarily store computed color results and to pass computed color between stages. Arguments for blending stage operations can be selected from: the four current-color registers, rasterized color (diffuse or specular), texture, the alpha components of the above colors, and 0 or 1. Up to sixteen independently programmable consecutive stages, forming a chain of blending operations, are supported for applying multiple textures to a single object in a single rendering pass.
