Abstract: A method of making a read sensor while protecting it from electrostatic discharge (ESD) damage involves forming a severable shunt during the formation of the read sensor. The method may include forming a resist layer over a plurality of read sensor layers; performing lithography with use of a mask to form the resist layer into a patterned resist which exposes left and right side regions over the read sensor layers as well as a shunt region; etching, with the patterned resist in place, to remove materials in the left and right side regions and in the shunt region; and depositing, with the patterned resist in place, left and right hard bias and lead layers in the left and right side regions, respectively, and in the shunt region for forming a severable shunt which electrically couples the left and right hard bias and lead layers together for ESD protection.

Abstract: A water filtration system incorporating a fluid flow meter has a modular turbine casing assembly in which a turbine is located between upstream and downstream casing elements of identical shape and formed to be stacked so as to trap the turbine in between. The turbine is magnetized and rotation of the turbine is monitored electronically with a reed switch having a lead wire which is positioned proximate to the turbine to sense fluctuations in a magnetic field created by the turbine on rotation of the turbine. The reed switch housing itself is disposed at a location remote from the turbine. The system further includes processor for calculating an adjusted accumulated count data for low volumetric flow rates which are less than a predetermined threshold value. Advantageously, the invention can be used to reliably measure very low flow rates with very little power drawn.

Abstract: A read head has a bottom lead made of material that is relatively polish resistant and a top lead layer that polishes down more easily than the bottom layer. With this structure, when the layers are deposited and then polished down, the top layer recesses away from the sensor (and bottom lead layer) in a controlled fashion, providing an acceptable lead structure that reduces the mismatch between the read head physical read width and magnetic read width.

Abstract: A suspended resist bridge suitable for lithographically patterning MR sensors having trackwidths narrower than 0.2 micron is fabricated using the method of the present invention. First, PMGI is spun onto a substrate to form a first thin resist layer. Next, PMMA is spun onto the first resist layer to form a second resist layer. The PMMA layer is exposed to an electron beam to pattern the trackwidth of the MR sensors. E-beam exposed PMMA is then developed in an IPA solution. The resist structure is then placed in a basic solution for dissolving PMGI, which results in a fully undercut resist bridge that is used for patterning the MR sensors.

Abstract: A method for transferring a pattern through a photoresist layer in the fabrication of submicron semiconductor devices structures is disclosed. A photoresist is provided on a substrate and the same is imagewise exposed with a desired pattern to form exposed and unexposed patterned areas in the top surface of the photoresist. The photoresist is then baked to form cross-linked regions in the exposed pattern areas of the photoresist. Silylation is then performed to incorporate silicon into the unexposed patterned areas of the photoresist, wherein some incorporation of silicon occurs in the exposed patterned crosslinked areas of the photoresist. The patterned photoresist is subsequently etched using a high density, low pressure, anisotropic O.sub.2 plasma alone to produce residue-free images with vertical wall profiles in the photoresist. This method is particularly advantageous with RFI reactive ion etch systems.
