Methods and apparatus for scanning a code on or in a transparent part, the method comprising: illuminating the code to generate a projected image of the code on a projection surface spaced from the transparent part; and machine scanning the projected image.

Method and system for scanning a code on a transparent part

A method of determining an operational status of a semiconductor manufacturing assembly uses internal vibrations of an in-situ assembly to detect defects. The method may include initiating a first test vibration in an internal structure of the semiconductor manufacturing assembly while the semiconductor manufacturing assembly is in-situ in a semiconductor processing chamber, receiving a first vibration signal caused by the first test vibration, transforming the first vibration signal into a first frequency domain representation of the first vibration signal, determining the operational status of the semiconductor manufacturing assembly based on the first frequency domain representation, and performing a corrective action for the semiconductor manufacturing assembly in response to the operational status.

Detecting defects of semiconductor manufacturing assemblies

Methods for texturing a surface of a component which include partially submerging the component within a liquid such that a first portion of the component is not submerged in the liquid and a second portion of the component is submerged in the liquid; and contacting at least the first portion of the component with a laser beam at a power and for a period of time sufficient to texture the first portion of the component to a first surface roughness, wherein the second portion of the component is either not textured by the laser beam, or is textured to a lesser degree than the first portion of the component and has a second surface roughness which is less than the first surface roughness.
