Latest Patents

Ahmad's latest patents include a sequential multilayer process for using fluorinated hydrocarbons and a method for creating double-sided hybrid high-density circuit boards. The first patent describes a method of forming a multilayer circuit board that involves a build-up process. This process begins with a solidified layer of dielectric on a substrate, where alternate layers of conducting metal and dielectric are sequentially deposited. Each layer is defined using photoresist and photolithographic techniques. After the lines are deposited, the photoresist is removed, and a second layer defines conductive posts that function as through holes between metal layers. The dielectric is then flowed into place and solidified to insulate adjacent metal lines and posts. This process can be repeated to build up layers of conducting metal and dielectric, ultimately forming a completed multilayer wiring board.

The second patent focuses on constructing a very fine line three-dimensional package without lamination during the assembly of the signal core. This method employs line and hole formation and planarization without drilling, which helps avoid excessive stress on the package during assembly. The construction involves a power core made from high dielectric constant material, with a signal core on both sides using low dielectric constant material. Photoresist techniques are utilized to define horizontal lines and vertical posts, and after metallization, the dielectric is flowed over the pattern to create a finished layer of the signal core. This sequence is repeated to build up the required wiring pattern.
