Eva M B Strzelecka

Introduction

Eva M B Strzelecka, an accomplished inventor based in Plymouth, Minnesota, has made significant contributions to the field of technology with a focus on semiconductor devices, particularly vertical cavity surface emitting lasers (VCSELs). With two patents to his name, Strzelecka's work showcases innovative techniques that enhance the performance and durability of these critical components.

Latest Patents

One of Strzelecka's latest patents involves protective side wall passivation for VCSEL chips. This invention outlines methods for sealing or passivating the edges of VCSEL chips, which are pivotal in optical communication technologies. The technique comprises oxidizing the edges of the die at the wafer level prior to slicing it into individual chips. The process begins by etching channels in the streets between the dies, allowing for the oxidation of the channel wall surfaces. This oxidation specifically targets the aluminum-bearing layers, such as AlAs and AlGaAs, converting them into a stable native oxide that is resistant to environmental degradation. Once the oxidation is complete, the wafer can be precisely cut along the channels, resulting in multiple die, each equipped with a protective oxide layer around its edges, enhancing their longevity and reliability.
