  • Publication number: 20190336961
    Abstract: Embodiments of lab automation workstations are disclosed in which the pod that performs pipetting operations is integrated with pipette tip-loading functionality. To generate the necessary tip-loading force, a dual drive system is used that is symmetric about the Y-axis to allow for offset or partial tip box loads by dynamically centering the drive force (e.g., the tip-loading force) over the reaction load. This minimizes the need for oversized linear motion components while still allowing for the generation of high tip-loading forces needed to properly load a large number of pipette tips simultaneously.

  • Patent number: 8274645
    Abstract: A method and apparatus for in-situ metrology of a workpiece disposed in a vacuum processing chamber. The apparatus may include an optical assembly external to the processing chamber configured to focus a relatively large optical spot over a relatively large working distance to acquire a TE and TM spectra from a periodic array on the workpiece. The workpiece may be disposed in the processing chamber with an arbitrary orientation which is first determined via a reflectance measurement. TE and/or TM spectra may then be acquired by initiating a periodic triggering of a flash lamp based on the determined workpiece orientation to account for variation in placement of the workpiece within the processing chamber. The periodic array from which spectra are collected may be a memory array being fabricated in a semiconductor wafer.

    Abstract: An apparatus for adaptive self-aligned dual patterning and method thereof. The method includes providing a substrate to a processing platform configured to perform an etch process and a deposition process and a metrology unit configured for in-vacuo critical dimension (CD) measurement. The in-vacuo CD measurement is utilized for feedforward adaptive control of the process sequence processing platform or for feedback and feedforward adaptive control of chamber process parameters. In one aspect, a first layer of a multi-layered masking stack is etched to form a template mask, an in-vacuo CD measurement of the template mask is made, and a spacer is formed, adjacent to the template mask, to a width that is dependent on the CD measurement of the template mask.

  • Patent number: 8089046
    Abstract: A method for determining the flow rate of a gas includes measuring a first concentration of a calibration gas provided to the process chamber at a first pressure and temperature by directing infrared radiation into the process chamber and monitoring a first amount of infrared radiation absorbed by the calibration gas. A mixture of a second gas and the calibration gas is provided to the process chamber while maintaining the first pressure and temperature. A second concentration of the calibration gas in the mixture is measured by directing infrared radiation into the process chamber and monitoring a second amount of infrared radiation absorbed by the calibration gas. A flow rate of the second gas is calculated by comparing the first and second concentrations of the calibration gas. In one embodiment, the calibration gas and the second gas may not absorb the infrared radiation at the same wavelength.

  • Publication number: 20110253671
    Abstract: An endpoint detection method for detecting an endpoint of a process comprises determining a reflectance spectrum of light reflected from a substrate, the light having a wavelength, processing the substrate while light having the wavelength is reflected from the substrate, detecting light having the wavelength after the light is reflected from the substrate, generating a signal trace of the intensity of the reflected light and normalizing the signal trace with the reflectance spectrum of the light. The normalized signal trace can then be evaluated to determine an endpoint of the process.
