  • Publication number: 20130015877
    Abstract: The present disclosure provides a method for testing a semiconductor device. The method includes providing a testing unit and an electronic circuit coupled to the testing unit and applying a first electrical signal to the testing unit. The method includes sweeping a second electrical signal across a range of values, the second electrical signal supplying power to the electronic circuit, wherein the sweeping is performed while a value of the first electrical signal remains the same. The method includes measuring a third electrical signal during the sweeping, the measured third electrical signal having a range of values that each correspond to one of the values of the second electrical signal. The method includes adopting an optimum value of the second electrical signal that yields a minimum value of the third electrical signal. The method includes testing the testing unit while the second electrical signal is set to the optimum value.

  • Patent number: 7160811
    Abstract: A method for fabricating a microelectronic fabrication employs an undoped silicate glass layer as an etch stop layer when etching a doped silicate glass layer with an anhydrous hydrofluoric acid etchant. The method is particularly useful for forming a patterned salicide blocking dielectric layer when fabricating a complementary metal oxide semiconductor device.

  • Patent number: 7015129
    Abstract: A novel method of forming a bond pad of a semiconductor device and a novel bond pad structure. Two passivation layers are used to form bond pads of a semiconductor device. A portion of the second passivation layer resides between adjacent bond pads, preventing shorting of the bond pads during subsequent wire bonding processes or flip-chip packaging processes.

  • Patent number: 6943062
    Abstract: The invention describes how contaminant particles may be removed from a surface without in any way damaging that surface. First, the positional co-ordinates of all particles on the surface are recorded. Optionally, only particles that can be expected to cause current or future damage to the surface are included. Then, using optical tweezers, each particle is individually removed and then disposed of. Six different ways to remove and dispose of particles are described.

  • Publication number: 20040266174
    Abstract: A method of reducing or substantially eliminating the number of tungsten plug pullouts and consequential chip failures by controlling the CMP step of removing the overfilled tungsten so as to leave a thin layer of tungsten instead of continuing the removal down to the top surface of the dielectric layer.

  • Patent number: 5990567
    Abstract: An integrated de-focus pattern provides an effective in-line monitor for photo processing steps of integrated circuit wafers. The de-focus pattern is formed on an integrated circuit wafer in the vertical and horizontal spaces between integrated circuit chips. The de-focus pattern has a number of different test patterns at different heights above the wafer surface. De-focus patterns are placed across the entire wafer surface. The de-focus patterns are formed at the same time the features of the circuit chips are formed. The de-focus patterns can be analyzed optically or using a scanning electron microscope.
