Introduction

David B Blumel is a notable inventor based in New York, NY, who has made significant contributions to the field of semiconductor technology. With a total of six patents to his name, Blumel has developed innovative methods that enhance the manufacturing processes of flip chips, which are essential components in modern electronics.

Latest Patents

Among his latest patents, Blumel has introduced a "Wafer Coating Method for Flip Chips." This method outlines a process for applying an underfill and edge coating to flip chips. The steps include adhering a bumped wafer to an expandable carrier substrate, sawing the wafer to create individual chips, and stretching the carrier substrate to form channels between the chips. The method also involves applying an underfill material to the bumped surfaces and edges of the chips, cutting the underfill material in the channels, and finally removing the individual, underfill-coated chips from the carrier.

Another significant patent is for a "Flip Chip with Integrated Mask and Underfill." This invention features a flip chip that includes solder bumps, an integrated underfill, and a separate flux coating. The underfill material is applied to the chip surface before the solder bumps, and it is treated to create apertures that act as a mask for the solder bump application. This innovation simplifies the manufacturing process by eliminating the need for a separate underfilling step.
