A method of manufacturing a semiconductor device able to reduce the number of manufacturing steps and attain the rationalization of a manufacturing line is disclosed. The semiconductor device is a high-frequency module assembled by mounting chip parts () and semiconductor pellets () onto each of wiring substrates () formed on a matrix substrate () after inspection. A defect mark () is affixed to a wiring substrate () as a block judged to be defective in the inspection of the matrix substrate (), then in a series of subsequent assembling steps the defect mark (e) is recognized and the assembling work for the wiring substrate () with the defect mark () thereon is omitted to attain the rationalization of a manufacturing line.

Apparatus and method for fabricating, sorting, and integrating materials with holographic optical traps

An apparatus and method for manipulating, effecting interaction of, photochemically transforming and/or sorting small dielectric particles or other materials. The apparatus and method involves use of one or more diffractive optical elements which each receive a laser beam and form a plurality of laser beams. These laser beams are operated on by a telescope lens system and then an objective lens element to create an array of optical traps for manipulating, effecting interaction of, photochemically transforming and/or sorting small dielectric particles or other materials.

The present invention relates to a system of applying optical gradient forces to form a plurality of optical traps to manipulate small particles. The system includes a light source for generating a focused beam of light which is directed along an optical axis though a phase patterning optical element having a variable optical surface and which has a virtual lens encoded thereon. The optical element produces a plurality of beamlets that are coverged at a position between the optical element and a single transfer lens, and directed through the transfer lens to overlap at the back aperture of a focusing lens. The focusing lens coverges the beamlets to form a plurality of optical traps in the working focal region where particles to be examined, manipulated, or measured, are disposed.

Apparatus for applying optical gradient forces

A method and apparatus for control of optical trap arrays and formation of particle arrays. The method and apparatus provides a laser and a time variable diffractive optical element to allow dynamic control of optical trap arrays and consequent control of particle arrays and also the ability to manipulate singular objects using a plurality of optical traps.

A method and apparatus for control of optical trap arrays and formation of particle arrays using light that is in the visible portion of the spectrum. The method and apparatus provides a laser and a time variable diffractive optical element to allow dynamic control of optical trap arrays and consequent control of particle arrays and also the ability to manipulate singular objects using a plurality of optical traps. By avoiding wavelengths associated with strong absorption in the underlying material, creating optical traps with a continuous-wave laser, optimizing the efficiency of individual traps, and trapping extended samples at multiple points, the rate of deleterious nonlinear optical processes can be minimized.
