Title: Kalpesh G Dave: Innovator in Photomask Error Correction

Introduction

Kalpesh G Dave is a notable inventor based in Bengaluru, India. He has made significant contributions to the field of photomask error correction, holding 2 patents that showcase his innovative approach to design error management in lithography.

Latest Patents

One of his latest patents focuses on photomask error correction. This invention involves an automated computer program that indexes and examines design errors generated by a mask rule check (MRC) program. The program connects to a false error pattern database and a real error pattern database, applying waivers to design errors when matching patterns are found. The output includes a list of design errors that remain unresolved by the automated program.

Another patent addresses lithographic error reduction through pattern matching. In this invention, a library of waivable images is generated, which includes images of regions from a reference design layout that contain raw errors identified by an optical rule checks (ORC) program. By generating error region images and matching them with the library, the invention effectively reduces the list of raw errors, leading to a more accurate identification of real errors.
