Title: Innovations of James Tynan Andrews

Introduction

James Tynan Andrews is a notable inventor based in Hopewell, NJ (US). He has made significant contributions to the field of semiconductor technology, holding a total of 2 patents. His work focuses on advancements in imaging technology and electroluminescent diodes.

Latest Patents

One of his latest patents is for an Electron Multiplication CMOS Imager. This invention includes a pixel that features at least one electron multiplication gain stage, which is configured in a loop and electrically coupled to a charge collection region and a charge readout region. The charge collection region generates a charge packet, while the EM gain stage amplifies this packet through impact ionization. The design allows for the charge packet to circulate a predetermined number of times, ultimately converting the amplified charge into a measurable signal. This pixel can be manufactured using a CMOS process and can include a second EM gain stage for increased amplification.

Another significant patent is for an Electroluminescent Diode with a Mode Expander. This invention involves a semiconductor electro luminescent diode that has a body with a pair of spaced opposed end surfaces and an active layer that extends from one end surface to a point spaced from the other end surface. The active layer is narrower than the distance between the side surfaces and features a tapered portion that comes to a point. The design allows for radiation generated in the active layer to emit a larger beam area from the pointed end, enhancing the diode's efficiency.
