Title: Joseph Edward Grigalunas: Innovator in Semiconductor Technology
Introduction
Joseph Edward Grigalunas is a notable inventor based in Dallas, TX (US). He has made significant contributions to the field of semiconductor technology, holding 2 patents that showcase his innovative approach to thermal control in semiconductor devices.
Latest Patents
His latest patents include an "Apparatus for thermal control of semiconductor chip assembly and underfill." This invention features a plate with a body and a surface that can be heated to a controlled temperature profile across various locations. The design includes mesas that maintain the same temperature and are configured to support portions of the substrate. Movable capillaries are incorporated to blow cooled gas onto selected areas of the assembly, while at least one movable syringe dispenses a polymer precursor.
Another significant patent is the "Thermal method to control underfill flow in semiconductor devices." This method involves flipping a chip with solder bodies onto a substrate after a reflow process, creating a gap between the chip and substrate. The apparatus controls the temperature profile across the plate, allowing for precise management of the polymer precursor's viscosity. This results in a controlled capillary flow that fills the gap without voids.
