Title: Innovations by Petrus T Appelman
Introduction
Petrus T Appelman is a notable inventor based in St. Catharines, Canada. He has made significant contributions to the field of electronics, particularly in the development of antifuse technology. With a total of 2 patents to his name, Appelman's work has implications for circuit design and manufacturing processes.
Latest Patents
Appelman’s latest patents include an innovative antifuse based on silicided polysilicon bipolar transistors. This improved antifuse utilizes the base-emitter junction of a silicided single polysilicon bipolar transistor. The design shortens the distance between the base metal and emitter metal, resulting from self-aligning process steps rather than traditional lithographic steps. This advancement leads to a lower and better-controlled programming voltage, programming energy, and ON state resistance. Typically, the conductive filament formed in this new antifuse measures about 0.65 microns long and is created by a voltage pulse with a relatively slow rise time of approximately 150 microseconds. These improvements provide significant advantages in circuit design and manufacturing.
Another patent by Appelman is a method of making an antifuse based on silicided single polysilicon bipolar technology. Similar to his previous patent, this method also employs the base-emitter junction of a silicided single polysilicon bipolar transistor. The benefits of this method include enhanced control over programming voltage and energy, as well as reduced ON state resistance, which are crucial for efficient circuit design.
