  • Patent number: 11929260
    Abstract: Embodiments of methods and apparatus for reducing warpage of a substrate are provided herein. In some embodiments, a method for reducing warpage of a substrate includes: applying an epoxy mold over a plurality of dies on the substrate in a dispenser tool; placing the substrate on a pedestal in a curing chamber, wherein the substrate has an expected post-cure deflection in a first direction; inducing a curvature on the substrate in a direction opposite the first direction; and curing the substrate by heating the substrate in the curing chamber.
    Type: Grant

  • Patent number: 11610807
    Abstract: Methods and apparatus for cleaving a substrate in a semiconductor chamber. The semiconductor chamber pressure is adjusted to a process pressure, a substrate is then heated to a nucleation temperature of ions implanted in the substrate, the temperature of the substrate is then adjusted below the nucleation temperature of the ions, and the temperature is maintained until cleaving of the substrate occurs. Microwaves may be used to provide heating of the substrate for the processes. A cleaving sensor may be used for detection of successful cleaving by detecting pressure changes, acoustic emissions, changes within the substrate, and/or residual gases given off by the implanted ions when the cleaving occurs.

  • Patent number: 11375584
    Abstract: Methods and apparatus for processing a substrate are provided herein. The apparatus can include, for example, a microwave energy source configured to provide microwave energy from beneath a substrate support provided in an inner volume of the process chamber; a first microwave reflector positioned on the substrate support above a substrate supporting position of the substrate support; and a second microwave reflector positioned on the substrate support beneath the substrate supporting position, wherein the first microwave reflector and the second microwave reflector are positioned and configured such that microwave energy passes through the second microwave reflector and some of the microwave energy is reflected from a bottom surface of the first microwave reflector back to the substrate during operation.
