  • SELF-ASSEMBLED MONOLAYER
    Publication number: 20120052329
    Abstract: A magnetic recording composite comprises a substrate, a plurality of layers deposited over the substrate, the plurality of layers defining an outer surface, and a self-assembled monolayer deposited over the outer surface of the plurality of layers. The self-assembled monolayer has an outer surface and comprises a plurality of molecules each having a head group bonded to the outer surface of the plurality of layers, a body group, and a tail group. The tail groups of the plurality of molecules form the outer surface of the self-assembled monolayer, and the self-assembled monolayer forms a substantially continuous layer over the outer surface of the magnetic recording layer.

  • Enhanced endpoint detection for wet etch process control
    Patent number: 6989683
    Abstract: Improved endpoint detection is obtained for wet etch and/or other chemical processes involving in situ measurement of bath impedance. The endpoint detection uses a measurement apparatus having a measurement circuit with a capacitor designed to alter the phase angle of the circuit. The capacitor is preferably a variable capacitor which is used to set the initial phase angle of the measurement circuit to about zero. The methods using the improved detection enable etch to be more precisely controlled even under conditions where noise would otherwise adversely impact determination of the endpoint.
