The stamping process and a method of fabrication of nano-stamps with characteristic dimensions below 1 nm and up to 100 nm intended for usage in making patterns of characteristic dimensions the same as those of the nano-stamp on surface of a substrate is provided. In the process a very hard stamp is fabricated by first depositing alternating layers of two materials, one of which has very high hardness, on some sacrificial substrate via PVD, CVD or any other deposition procedure that produces alternating layers of selected thickness, from sub 1 nm to above 100 nm. The layered film is then polished to an atomically smooth finish perpendicular to the plane of the layers and etched to produce dips in the softer layers. These steps produce a grid of parallel elevations and valleys on the etched surface, which now can be used as a stamp to stamp out patterns on a substrate of lower hardness than the hardness of the elevated layers. If the substrate is stamped twice with a turning of the stamp 90 degrees between first and second stampings, a square pattern of elevations or hills and valleys is formed, which can be used for magnetic memory storage by subsequently sputtering magnetic material on the tops of the elevations or hills.

A multilayer exchange spring recording media consists of a magnetically hard magnetic storage layer strongly exchange coupled to a softer nucleation host. The strong exchange coupling can be through a coupling layer or direct. The hard magnetic storage layer has a strong perpendicular anisotropy. The nucleation host consists of one or more ferromagnetic coupled layers. For a multilayer nucleation host the anisotropy increases from layer to layer. The anisotropy in the softest layer of the nucleation host can be two times smaller than that of the hard magnetic storage layer. The lateral exchange between the grains is small. The nucleation host decreases the coercive field significantly while keeping the energy barrier of the hard layer almost unchanged. The coercive field of the total structure depends on one over number of layers in the nucleation host. The invention proposes a recording media that overcomes the writeability problem of perpendicular recording media.

The prosthetic device is composed of at least two essentially parallel soft layers of an elastically deformable hydrogel and at least one rigid layer, the rigid layer having less compressibility than the soft layers, being adjacent to the soft layers, parallel to them, and firmly attached to them.

The invention described in this disclosure is an apparatus and method for clamping semiconductor wafers or other substrates or workpieces during etching, CVD, or surface modification processes. The purpose of the invention is to achieve improved heat transfer during processing between the wafer / substrate and a temperature controlled pedestal used for supporting it in the process chamber. The typical level of process heat put into the wafer during plasma-based etching or deposition processes will be up to about 10 Watts per centimeter squared while the maximum acceptable temperature differential between wafer / substrate and pedestal is less than about 100 Celsius. In such low gas pressure environments typical for plasma-based processes, the heat removal from the wafer / substrate by gaseous conduction may be inadequate to meet requirements. This invention achieves excellent heat transfer to the pedestal from the wafer / substrate when there is a thin, resilient, electrically insulating layer (tape) bonded to the wafer / substrate or the pedestal. Wafer / substrate clamping for improved process heat removal is achieved by a combination of vacuum clamping of the wafer / substrate beginning prior to evacuation of the processing chamber, along with or followed by electrostatic clamping of the wafer / substrate which continues during processing. The invention also permits the wafer / substrate to be rapidly and safely released from the electrostatic clamping when the chamber is returned to atmospheric pressure by a providing a slight pressure increase, above atmospheric pressure, between wafer and pedestal. The pedestal may have some roughening or narrow grooves on the wafer clamping surface, and some small holes from its surface leading to an evacuated plenum or channel within the pedestal. Alternatively, the pedestal may have a layer of a porous metal extending from its surface down to the evacuated channel or plenum which permits gas to be evacuated. These structures allow vacuum pumping of gas that might otherwise be trapped between the insulating layer and the pedestal. When a wafer / substrate is placed on the pedestal by loading at atmospheric pressure, vacuum pumping through the pedestal is commenced. This causes the workpiece to be pressed to the pedestal clamping surface with approximately atmospheric pressure compressing the soft layer against its clamping surface. This provides sufficient contact of the soft layer with the pedestal to greatly improve heat transfer from the wafer / substrate to the pedestal. A voltage is applied to the pedestal, beginning any time after the wafer is on the pedestal, to further clamp the wafer electrostatically. As the processing chamber is then pumped down to operating pressure for processing the electrostatic clamping voltage maintains sufficient pressure of the wafer / substrate against the pedestal to maintain the heat conductive contact between the soft layer and the pedestal. This permits good heat conduction to be maintained during the low pressure plasma-based etching or CVD processing. Following processing when the wafer / substrate is to be removed it may be rapidly de-clamped from the electrostatic clamping by application of a slight over-atmospheric pressure in the reservoir or pumping channels within the pedestal.

The cell is configured using a pattern with four lobes to store two bits, and eight lobes to store three bits. The resulting cell can be used to provide a fast, non-volatile magnetic random access memory (MRAM) with high density and no need to rewrite stored data after they are read, or as a fast galvanic isolator.

A male sexual impotence treatment apparatus includes an elongate adjustable constriction member extending in a loop around a male patient's penile tissue or the prolongation thereof. An adjustment device adjusts the longitudinal extension of the constriction member in the loop to temporarily constrict the penile tissue or the prolongation thereof to restrict the penile exit blood flow to achieve erection. A layer of a soft viscoelastic material is applied on the constriction member such that it is located between the constriction member and the patient's penile tissue or the prolongation thereof at least along a portion of the constriction member to protect the penile tissue or the prolongation thereof from being eroded by the constriction member. The layer has an inwardly directed radial extension in the loop such that, when the adjustment device is operated to decrease the longitudinal extension of the constriction member in the loop, the soft layer is forced to expand radially inwardly in the loop causing a corresponding increased constriction of the penile tissue or the prolongation thereof.
