US Patent:

20220326150, Oct 13, 2022
Filed:

Mar 30, 2022
Appl. No.:

17/709222
Inventors:

- Livermore CA, US
Jun Jiang - Fremont CA, US
International Classification:

G01N 21/39
G01J 3/42
Abstract:

In one aspect, a method of detecting a trace gas is disclosed. The method includes containing the trace gas in an optical cavity. The method further includes injecting a first laser light from a first laser into the optical cavity causing the trace gas to transition from an energy state lower that a first excited energy state to the first excited energy state, and injecting a second laser light from a second laser into the optical cavity causing the trace gas to transition from the first excited energy state to a second excited energy state. The method includes measuring, by a detector, a first cavity ringdown intensity as a function of time after turning off the second laser with the first laser on, and a second cavity ringdown intensity as a function of time after turning off the second laser with the first laser off.

Assignee:

ASML Netherlands B.V. - Veldhoven
International Classification:

H01J 37/28
H01J 37/244
H01J 37/26
Abstract:

Apparatuses, systems, and methods for providing beams for controlling charges on a sample surface of charged particle beam system. In some embodiments, a module comprising a laser source configured to emit a beam. The beam may illuminate an area adjacent to a pixel on a wafer to indirectly heat the pixel to mitigate a cause of a direct photon-induced effect at the pixel. An electron beam tool configured to detect a defect in the pixel, wherein the defect is induced by the indirect heating of the pixel.

US Patent:

20200074910, Mar 5, 2020
Filed:

Nov 7, 2019
Appl. No.:

16/677522
Inventors:

- Cupertino CA, US
Deniz Teoman - San Mateo CA, US
Jiaying Wu - San Jose CA, US
John Z. Zhong - Saratoga CA, US
Jun Jiang - Campbell CA, US
International Classification:

G09G 3/20
G09G 3/34
Abstract:

An electronic device may include a display having an array of display pixels and having display control circuitry that controls the operation of the display. The display control circuitry may adaptively adjust the spectral characteristics of display light emitted from the display to achieve a desired effect on the human circadian system. For example, the display control circuitry may adjust the spectral characteristics of blue light emitted from the display based on the time of day such that a user's exposure to the display light may result in a circadian response similar to that which would be experienced in natural light. The spectral characteristics of blue light emitted from the display may be adjusted by adjusting the relative maximum power levels provided to blue pixels in the display or by shifting the peak wavelength associated with blue light emitted from the display.
