A spindle motor structure includes a rotor, a stator accommodated mainly inside the rotor, and an internal roof magnet located on an inner roof surface of a rotor bell of the rotor. The internal roof magnet further has an inner rim and an outer rim. The inner rim is located projection-wisely within a range of a hollow shaft of the stator. The outer rim is located projection-wisely between an internal peripheral surface of the rotor bell and an inner edge of a coil of the stator. By providing the...

A control circuit for detecting the reflected voltage of a transformer is provided. A detection circuit is developed for sampling the reflected voltage. Because the pulse width of the reflected voltage is narrower at light load, a bias circuit is utilized for producing a bias signal to help the reflected voltage detection. Furthermore, a blanking circuit ensures a minimum pulse width of the reflected voltage.

The present disclosure provides a system and method for a tape-out request. In one example, the method includes receiving initial information from a customer and loading a mask tooling template based on the initial information. A mask tooling form may be customized based on metal layer information provided by the customer via the mask tooling template and answers to questions provided to the customer. The method may then generate logical operations based on information received from the customer...

A switching regulator includes a switching device to switch a transformer from a primary-side to secondary side. A control circuit generates a switching signal for regulating output of the switching regulator. The control circuit includes a first circuit to generate a first signal and a timing signal by measuring a reflected signal of the transformer. A second circuit produces a second signal by integrating a current signal with the timing signal. The current signal represents a primary-side swi...

The disclosure relates to a method and apparatus for enhancing copper film quality with a two-step deposition. The two step deposition may include depositing a first copper film by electrochemical plating, annealing the first copper film at a desired temperature for a duration of time to remove any impurities, depositing a second copper film and annealing the second copper film for a duration of time to remove impurities. The second copper film can be deposited by electrochemical plating without...

A novel method for preventing the formation of voids in metal interconnects fabricated on a wafer, particularly during a thermal anneal process, is disclosed. The method includes fabricating metal interconnects between metal lines on a wafer. During a thermal anneal process carried out to reduce electrical resistance of the interconnects, the wafer is positioned in spaced-apart relationship to a wafer heater. This spacing configuration facilitates enhanced stabilility and uniformity in heating o...

A method for translating mask tooling information comprises the steps of: receiving a plurality of input mask tooling forms for fabricating a wafer, at least two of the plurality of input masking tool forms having respectively different sequences of layers; forming a template having a sequence of layers formed by the union of the different sequences of layers; and translating information from each of the input mask tooling forms to fit the template.

The present invention provides peptide mimics for GD3 ganglioside. The peptide mimics were identified by panning phage display peptide libraries with an anti-GD3 monoclonal antibody. The peptide mimics inhibit the binding of an anti-GD3 antibody to GD3 positive cells and also elicit antibodies which can bind to GD3 positive cells. The identified peptide mimics can be used as immunogens for cancer therapy.
