Appl. No.:

17/677716

Inventors:

- Palo Alto CA, US
Clinton Smith - San Francisco CA, US
David Eric Schwartz - San Carlos CA, US
Yong Zhang - Millbrae CA, US
Vedasri Vedharathinam - Sunnyvale CA, US

International Classification:

G01N 27/04
B01J 20/20
B01J 20/02
B01J 20/32
G01N 33/00
G01N 27/12

Abstract:

Disclosed herein are methods of producing metal nanoparticle-decorated carbon nanotubes. The methods include forming a reaction mixture by combining a first solution with a second solution, wherein the first solution comprises polymer-coated metal nanoparticles comprising metallic nanoparticles coated with a polymer, and wherein the second solution comprises carbon nanotubes. The methods also include heating the reaction mixture to a temperature greater than a glass transition temperature of the polymer for a time sufficient to cause the polymer-coated metal nanoparticles to bind to the carbon nanotubes forming the metal nanoparticle-decorated carbon nanotubes.

Appl. No.:

16/158774

Inventors:

- Milpitas CA, US
Jan Lauber - San Francisco CA, US
Yong Zhang - Cupertino CA, US

International Classification:

G06T 7/00
G01N 21/95
G01N 21/88
G01N 21/956
G06T 7/11

Abstract:

The present disclosure describes methods, systems, and articles of manufacture for performing a defect inspection of a die image using adaptive care areas (ACAs). The use of ACAs solve the problem of handling rotations of components that require rotating care areas; handling the situation where each care area requires its own rotation, translation, or affine transformation; and the situation of decoupling intensity differences caused by defects or process variation from intensity differences caused by size variations.
