Disclosed herein are a method of manufacturing a solder bump on a semiconductor device, a solder bump structure formed on a substrate, and an intermediate solder bump structure. In one embodiment, the method includes creating a bonding pad over a semiconductor substrate, and placing a mask layer over the substrate and the bonding pad. The method also includes forming an opening in the mask layer having a primary solder mold and at least one secondary solder mold joined with the primary mold, where the opening exposes a portion of the bonding pad. In this embodiment, the method further includes filling the primary solder mold and the at least one secondary solder mold with solder material to form corresponding primary and at least one secondary solder columns in electrical contact with the bonding pad. The method also includes removing the mask layer after the filling of the solder molds with the solder material. The method still further includes reflowing the solder material to form a primary solder bump from the solder material of the primary solder column and at least a portion of the solder material from the at least one secondary solder column through cohesion of the solder material from the at least one secondary solder column to the primary solder column when melted.

Disclosed herein are intermediate and solder bump structures. In one embodiment, a structure comprises a primary solder column comprising primary solder material and configured to electrically contact a bonding pad on a semiconductor substrate. The structure also comprises at least one secondary solder column comprising secondary solder material in electrical contact with the primary solder column, the at least one secondary column having a height and volume less than a height and volume of the primary solder column. In such structures, the primary solder column is further configured to form a primary solder bump comprising the primary solder material and at least a portion of the secondary solder material through cohesion from the at least one secondary solder column when the intermediate structure undergoes a reflow process.

A multi-winding high step-up DC-DC converter includes a three-winding transformer to transform a low DC voltage to a high DC voltage; a power switch to control the energy flux of the primary winding of the three-winding transformer based on turning on/off the power switch; a first diode to control the current of the first secondary winding of the three-winding transformer; a second diode to control the current of the second secondary winding of the three-winding transformer; and a third diode to control the current of the primary winding. When the DC-DC converter is in the first operation state, the switch and the second diode are in on state, and the first and the third diodes are in off state. When the DC-DC converter is in the second operation state, the switch and the second diode are in off state, and the first and the third diodes are in on state.

The invention provides an antiglare film. A resin layer is disposed on a substrate. Micro-aggregates are distributed in an interior and over a surface of the resin layer. Each of the micro aggregates has a size of 0.1-3 μm and is formed by aggregating aggregated nano-particles. The micro-aggregates distributing over the surface result in a surface roughness of the resin layer. The weight ratio of the resin layer to the micro-aggregates is 1:0.1-0.7.

A gate process and a gate process for an embedded memory device. A semiconductor silicon substrate has a memory cell area and a logic circuit area. A first dielectric layer is formed overlying the semiconductor silicon substrate, and then a gate structure is formed overlying the first dielectric layer of the memory cell area. Next, a protective layer is formed overlying the first dielectric layer and the top and sidewall of the gate structure. Next, an insulating spacer is formed overlying the protective layer disposed overlying the sidewall of the gate structure. Next, a pre-cleaning process is performed to remove the protective layer and the first dielectric layer overlying the logic circuit area. Next, a second dielectric layer is formed overlying the logic circuit area, and then a gate layer is formed overlying the second dielectric layer of the logic circuit area.
