Title: Iqbal K Bansal: Innovator in Semiconductor Technology

Introduction

Iqbal K Bansal is a notable inventor based in Sandy Hook, Connecticut. He has made significant contributions to the field of semiconductor technology, holding two patents that showcase his innovative approach to solving complex problems in this industry.

Latest Patents

One of his latest patents is an in-situ method for producing a hydrogen-terminated hydrophobic surface on a silicon wafer. This method involves loading at least one silicon wafer into a closed vessel containing a solution of ammonium hydroxide, hydrogen peroxide, and deionized water. After removing the acidic solution, deionized water is introduced until the wafers are fully immersed. Following this, a second solution containing hydrofluoric acid, hydrochloric acid, and deionized water is added. As this solution is drained, an alcohol solution in a hot, low-pressure nitrogen carrier gas is introduced, ensuring that the wafer surface is dried and hydrogen-terminated, resulting in a hydrophobic surface. This innovative technique is performed in a single vessel, streamlining the process.

Another significant patent by Bansal is a wafer backing insert for a free mount semiconductor polishing apparatus. This invention features a backing insert with a diameter smaller than that of the semiconductor substrate being polished. This design allows for more precise material removal at the edges of the substrate, improving the overall thickness and total thickness variation (TTV) of the polished substrate. The process combines this innovative backing insert with a conventional one to achieve optimal results.
