Gregory C. Lee - Belmont CA

Assignee:

Lam Research Corporation - Fremont CA

International Classification:

B24D 1100

US Classification:

451537, 451526, 451529, 451533, 451534, 451538, 451539

Abstract:

A composite polishing pad for use in a linear chemical-mechanical polishing apparatus is provided. The pad comprises a hard polishing pad having a polishing surface and an attachment surface opposite the polishing surface, the attachment surface comprising a border comprising an adhesive, the border surrounding a cavity, the cavity being sized and shaped to receive a soft polishing pad. The soft polishing pad is disposed completely in the cavity and completely fills the cavity, and the soft polishing pad has a first side adhered in the cavity of the hard polishing pad, and a second side comprising an adhesive, whereby the attachment surface of the hard polishing pad and the second side of the soft polishing pad are substantially in a common plane. Other composite polishing pads are also provided, as are methods for making composite pads and methods for preventing composite pads from splitting apart into their component pads.

International Classification:

H04B 1008

US Classification:

398 25, 356450

Abstract:

An optical sampling method and apparatus use a probe pulse source of a predetermined optical wavelength range, e. g. , 1560 nm, to sample incoming optical pulses in approximately the same wavelength range. The probe pulse source is frequency-doubled e. g. , using a frequency doubler such as a nonlinear PPLN crystal, to obtain an intermediate second harmonic which may be filtered with a 780 nm bandpass filter to eliminate at least source frequency noise background. The filtered intermediate second harmonic is then mixed with the user input signal using an optional polarizing beam splitter and a dichroic beam splitter. The mixed signal is sent to a sum frequency generating (SFG) nonlinear crystal, e. g. , a PPLN crystal, where the resulting frequency is near the third harmonic. The output from the SFG PPLN crystal may be filtered using a bandpass 515 nm filter to remove unwanted wavelengths and processed to measure/sense the near third harmonic content using a photomultiplier tube (PMT).
