A perpendicular write head including a main pole and a trailing shield, the main pole being made of a diamond-like carbon (DLC) layer as hard mask and a rhodium (Rh) layer as shield gap, both DLC and Rh layers being CMP stop layers so as to avoid corner rounding and damage from chemical mechanical planarization (CMP) process, the DLC layer being removed by reactive ion etching (RIE) to create a trench, the trailing shield being deposited into the trench for self alignment.
摘要:
In an elliptical step exercise apparatus where stride length can be varied the various user programs can take advantage of this feature to provide for an enhanced workout. A control system can be used to implement a preprogrammed exercise routine such as a hill program where stride is shortened as the user goes up a simulated hill and lengthened as the user goes down the hill. In an interval training program, stride length can be increased and decreased at periodic intervals. In a cross training program, stride length can be decreased when the user is pedaling backwards and increased when the user is pedaling forwards.

A wireless code symbol reading system including a wireless hand-supportable code symbol reader in two-way RF communication with a base station operably connected to a host system, by way of an RF-based wireless data communication link having a predetermined RF communication range over which two-way communication of data packets can occur. The wireless hand-supportable code symbol reader is programmed to automatically detect when it is located inside and outside of the predetermined RF communication range. When the wireless reader is inside the RF communication range, then symbol character data is automatically transmitted to the base station, and when the wireless reader is located outside of the RF communication range, then symbol character data is automatically collected and stored in a data packet buffer, until the wireless reader has re-entered its RF communication range.

A Chemical Mechanical Polish (CMP) process and slurry therefore slurry that is capable of removing NiFe, SiO2, Photoresist, Ta, alumina and Cu at substantially the same rate. The slurry is useful for obtaining a substantially planar surface of several materials while avoiding corrosion of Cu coil and NiFe structure.

Bioluminescent imaging has proven to be a valuable tool for monitoring physiological and pathological activities at cellular and molecular levels in living small animals. Using biological techniques, target cells can be tagged with reporters which generate characteristic photons in a wide spectrum covering the infra-red range. Part of the diffused light can reach the body surface of a subject/specimen (e.g., a small animal), be separated into several spectral bands using optical means, and collected by a sensitive camera. Systems and methods are disclosed herein for multi-spectral bioluminescence tomography (MBLT), in which an image of an underlying 3D bioluminescent source distribution is synergistically reconstructed from spectrally resolved datasets externally measured. This MBLT process involves two or multiple imaging modalities that produce structural information of the object and optical properties of the object as well to enable and improve the quality of MBLT.
摘要:
A method is described for thin film processing using a selected CMP slurry with a silicon dioxide stop layer. The slurry includes an abrasive, preferably alumina, a corrosion inhibitor, preferably benzotriazole (BTA), and an oxidizer preferably hydrogen peroxide. The method is particularly useful for fabricating thin film heads where alumina is used as the dielectric. The method can be used to planarize metal structures surrounded by alumina in magnetic heads. The alumina refill is deposited to the final target height which is slightly below the height of the metal. A thin silicon dioxide stop layer is deposited over the alumina. The CMP is executed using the selected slurry to planarize the wafer down to the stop layer. Preferably only a negligible amount of the stop layer remains and the height of the metal structure is essentially the same as the deposited height of the refilled alumina.
摘要:
A chemical-mechanical nanogrinding process achieves near-zero pole tip recession (PTR) to minimize magnetic space loss of the head transducer to media spacing loss, alumina recession/trailing edge profile variation, and smooth surface finish with minimal smearing across multi-layers of thin films and the hard substrate to meet the requirements of high areal density head. With a fine lapping plate with a fixed-abrasive nanogrinding process, PTR can be improved to a mean of about 1.0 nm.

A preferred chemical mechanical polishing (CMP) method includes a CMP polishing compound including alumina abrasive particulates, 1H-Benzotriazole (BTA), and hydrogen peroxide (H2O2). A cleaning solution for CoFeNi structures in alumina fill of the present invention preferably includes 4-Methyl-1H-Benzotriazole in a concentration range of from 1% to 5%, 5-Methyl-1H-Benzotriazole in a concentration range of from 1% to 5%, hydrogenated 4-Methyl-1H-Benzotriazole in a concentration range of from 1% to 5%, hydrogenated 5-Methyl-1H-Benzotriazole in a concentration range of from 1% to 5%, sodium octanoate in a concentration range of from 5% to 10%, and water in a concentration range of from 65% to 95%. The cleaning solution is typically used with DI water to create an applied solution having a range of from 0.1% to 10% by volume of the cleaning solution.
