An apparatus for forming a solar cell includes a housing defining a vacuum chamber, a rotatable substrate support, at least one inner heater and at least one outer heater. The substrate support is inside the vacuum chamber configured to hold a substrate. The at least one inner heater is between a center of the vacuum chamber and the substrate support, and is configured to heat a back surface of a substrate on the substrate support. The at least one outer heater is between an outer surface of the vacuum chamber and the substrate support, and is configured to heat a front surface of a substrate on the substrate support.

Apparatus and method for producing solar cells

Compositely micro-textured thin film, magnetic disc media, with methods and apparatus for producing such, which are characterized by the incorporation of a first stage of micro-texturing provided by etching of a disc substrate, with a second, disparate, micro-texturing stage depositing rounded globules of eutectic alloy on the etched substrate.

Enhanced methods and apparatus for producing micro-textured, thin film, magnetic disc media and compositely micro-textured disc media produced thereby

Hydrogen-treated, sputter deposited, titanium nodules providing enhanced micro-texturing for thin film, magnetic, disk media.

Micro-texturing for sputtered, thin film magnetic media disks utilizing

An enhanced magnetic head is characterized by sputter induced, micro-texturing yielding rounded globular configurations on slider rail portions. Optimally, this enhanced head is employed in combination with sputter induced micro-textured thin film disk media having a surface or coarseness greater than that of the magnetic head.

Sputter induced micro-texturing enhancement for magnetic head structures

Sputter induced micro-texturing of thin film magnetic media discs entailing the formation of micro-texturing globules comprising a eutectic alloy of Indium and Bismuth.

Magnetic recording disc having a substrate, oxide layer, and a texture

Thin film disk media which is initially coated with lubricant from the ID or normal head landing area radially outwardly across the data zone. The initially applied lubricant area is thinned and buffed in the data area so as to provide a substantially reduced lubricant layer overlying the data zone characterized by markedly improved coefficient of friction characteristics in relation to what would have been produced without such lubricant removal and buffing.

Magnetic disk having enhanced zone lubrication

Method of fabricating sputter induced, micro-texturing of thin film,

Thin film media characterized by the utilization of a substantially peritectic seed alloy layer which is sputter deposited so as to provide dispersed, substantially peritectic and homogenous globules underlying subsequently deposited media layers. These media layers may include a metal layer such as chrome and a magnetic layer such as an alloy of cobalt, chromium, and platinum and possibly other ingredients.

Magnetic recording medium having an intermediate layer comprising

Method and magnetic transducer head characterized by enhanced coating of wear resistant carbon layer over an insulating short circuit, preventing layer on a magnetic, data transferring, head.

Method for applying a protective coating on a magnetic recording head

A discontinuous flash chrome interlayer of about 5 to 25 .ANG. is incorporated between the upper and lower magnetic recording alloy layers. This flash non-magnetic separation layer is so thin that it is, in fact, a discontinuous layer, so that while the benefits of having some chrome flashed on the surface of the first portion of the magnetic recording alloy are achieved, yet the upper and lower magnetic recording alloy layers are not completely physically separated as they are in disks made according to known sputtering processes.

Flash chromium interlayer for improved hard disk magnetic recording

Method for enhancing the magnetic and roughness properties of thin film

A thin-film disc fabrication method and structure contemplates a sputtered undercoat. An aluminum base is subjected to a fine polishing step, and a relatively thin undercoat is deposited by sputtering. The preferred undercoat is a 0.3-3 micron layer of nickel-vanadium alloy (on the order of 7% vanadium). The preferred recording layer is a sputtered composite structure comprising a layer of chromium and an overlying layer of a cobalt-chromium alloy. Modulation effects can be substantially eliminated by heating the aluminum base prior to sputtering the nickel-vanadium undercoat, and by oxidizing the undercoat prior to deposition of the overlying layers.
