Title: Innovations of James G. Serdy in Semiconductor Technology

Introduction

James G. Serdy is a prominent inventor based in Boston, MA (US), known for his significant contributions to semiconductor technology. With a total of 7 patents, Serdy has made remarkable advancements in the field, particularly in the recrystallization of semiconductor wafers.

Latest Patents

One of Serdy's latest patents involves semiconductor wafers recrystallized in a partially surrounding thin film capsule. This innovative process begins with an original wafer, typically silicon, which is designed to take the form of a desired end photovoltaic (PV) wafer. The original wafer may be produced through rapid solidification or chemical vapor deposition (CVD) and features small grains. It is encapsulated in a clean thin film that protects the silicon during recrystallization, allowing for the creation of a larger grain structure. The capsule can be formed by heating the wafer in the presence of oxygen or steam, resulting in a silicon dioxide layer on the outer surface, typically measuring 1-2 microns. Support elements are utilized to hold the wafer in place while minimizing contact with the film-forming atmosphere. The capsule effectively contains the molten material during recrystallization, safeguarding against impurities, and the process can occur in air. After recrystallization, the capsule is removed.

Another notable patent by Serdy focuses on the recrystallization of semiconductor wafers in a thin film capsule and related processes. Similar to his previous patent, this invention involves an original silicon wafer that is encapsulated in a clean thin film. The process includes further heating to create a molten zone through which the wafer travels, resulting in recrystallization with a larger grain size. The capsule again serves to contain the molten material and protect against impurities, with thermal transfer through backing plates minimizing stresses and defects. After the recrystallization process, the capsule is removed.
