摘要:
A method of forming a micromagnetic device on a substrate including forming a first insulating layer above the substrate, a first seed layer above the first insulating layer, a first conductive winding layer above the first seed layer, and a second insulating layer above the first conductive winding layer. The method also includes forming a first magnetic core layer above the second insulating layer, a third insulating layer above the first magnetic core layer, and a second magnetic core layer above the third insulating layer. The method still further includes forming a fourth insulating layer above the second magnetic core layer, a second seed layer above the fourth insulating layer, and a second conductive winding layer above the second seed layer and in vias to the first conductive winding layer. The first and second conductive winding layers form a winding for the micromagnetic device.

A power converter including a power train, a controller and a driver. The power train includes a switch that conducts for a duty cycle and provides a regulated output characteristic for the power converter, and a micromagnetic device interposed between the switch and the output of the power converter. The micromagnetic device includes a substrate, and a magnetic core layer formed over the substrate from a magnetic alloy including iron, cobalt and phosphorous. A content of the cobalt is in a range of 1.8 to 4.5 atomic percent. A content of the phosphorus is in a range of 20.1 to 30 atomic percent. A content of the iron is substantially a remaining proportion of the magnetic alloy. The controller provides a signal to control the duty cycle of the switch. The driver provides a drive signal to the switch as a function of the signal from the controller.

A method of electroplating iron or an iron alloy with a solution containing an iron-chelating agent to catalytically cycle the undesirable Fe(III) species back to Fe(II) for electroplating. The iron-chelating agents may be siderophores, specifically, for example, desferrioxamine E, desferrioxamine B, alcaligin, bisucaberin, putrebactin, rhodotorulic acid, enterobactin, vibriobactin, azotochelin, myxochelin, fluvibactin, and serratiochelin.

This invention involves a fiber probe device and a method of making it. The probe includes a relatively thick upper cylindrical region, typically in the form of a solid right circular cylinder, terminating in a tapered region that terminates in a relatively thin lower cylindrical region (tip), typically also in the form of a solid right circular cylinder, the lower region having a width (diameter) in the approximate range 0.01 .mu.m to 150 .mu.m.

摘要:
A method of photochemically reducing iron(III) species in an iron or iron alloy plating solution by adding an additive to the electroplating solution; contacting the additive with iron(III) species to form an iron(III)-additive species; and irradiating the electroplating solution, wherein the radiation is of sufficient energy to reduce the iron(III) in the iron(III)-additive species to iron(II). The additive comprises hydroxycarboxylic acids and their lactones.
