  • Patent number: 10103049
    Abstract: The method and the apparatus prevents the deformation of a substrate, e.g. a wafer, supported with its edge area or periphery at a support or chuck, and also avoids the damage and/or contamination of the active area of the substrate. In particular, the substrate is mechanically supported at its peripheral or edge portion, namely in the non-active area of the substrate, only; an additional non-mechanical extended support is provided in the active area by a gas cushion. The gas cushion is generated by a controllable nozzle or purge for a distinct and controlled compensation of the downward deflection of the substrate.

  • Patent number: 9960061
    Abstract: A method for curing at least in part a photoresist applied to a substrate comprises the following steps: The substrate coated with the photoresist is arranged on a support. The photoresist is subjected to a suitable temperature for curing the photoresist for a first predetermined time period. After the first predetermined time period has passed, the substrate is lifted from the support, rotated, re-placed onto the support and subjected to a suitable temperature for curing the photoresist for a second predetermined time period. This method can be performed with a device for curing at least in part a photoresist applied to a substrate, comprising a chamber, a support which is arranged in the chamber and on which the substrate can be arranged, and a rotating device for rotating the substrate between a first and a second phase of the curing of the photoresist.

  • Publication number: 20180082965
    Abstract: A semiconductor structure includes an electrically conductive structure formed upon an uppermost organic layer of a semiconductor substrate. A capping layer is formed upon the uppermost organic layer covering the electrically conductive structure. A maskless selective removal lasering technique ejects portions of the capping layer while retaining the portion of the capping layer covering the electrically conductive structure. Portions of the capping layer are ejected from the uppermost organic layer by a shockwave as a result of the laser beam vaporizing the uppermost organic layer of the semiconductor substrate. Portions of the capping layer contacting the electrically conductive structure are retained by the conductive structure dissipating heat from the laser that would otherwise vaporize the uppermost organic layer of the semiconductor substrate.

  • Patent number: 9864277
    Abstract: The invention relates to a method for regulating a light source of a photolithography exposure system which comprises a plurality of LEDs, by means of the following steps: the light output of the individual LEDs in specific wavelength ranges is detected, and the detected light output is compared with a desired light output distribution over the entire spectrum. The LEDs are operated such that the desired spectral light output distribution is achieved in the most precise manner possible. The invention also relates to an exposure assembly for a photolithography device, having a light source which comprises a plurality of LEDs, a control means which controls the electrical power supplied to the individual LEDs, and a sensor which can detect the light output of the LEDs in the respective ranges of the wavelengths.

  • Patent number: 9859141
    Abstract: A device for locating and engaging a notch on the perimeter of a circular wafer includes a notch locating component and a first plate. The notch locating component is configured to move linearly along a first axis and includes a front elongated component extending along a second axis perpendicular to the first axis and having a front surface, a back surface opposite to the front surface and a first protrusion extending from the front surface of the elongated component. The first protrusion has a shape complementing the shape of a notch formed on the perimeter of a circular wafer. As the notch locating component is driven toward the perimeter of the circular wafer along the first axis, a distance between the back surface of the elongated component and a front surface of the first plate is measured and the value of the measured distance is used to determine engagement of the first protrusion with the notch.
