Latest Patents

Bruno Spuler's latest patents showcase his innovative approach to semiconductor design and manufacturing. One notable patent describes a method of forming an isolation layer and manufacturing a trench capacitor. This process utilizes a two-step etch technique that creates a vertical collar oxide within the trench capacitor, with the first step involving CF/SiF/O chemistry to open the bottom of the trench collar. The second stage employs CF chemistry to eliminate any residual silicon oxide. This method ensures uniformity in the thickness of the PAD-nitride layer and guarantees an adequate collar oxide thickness, making it particularly useful for deep trench capacitors in dynamic random-access memory (DRAM) devices.

Another significant patent focuses on a semiconductor device with a self-aligned contact and the corresponding manufacturing method. In this invention, a first and a second conductor are established on a semiconductor substrate's surface. Both conductors are enveloped by encapsulants that include materials such as titanium oxide, boron nitride, silicon carbide, magnesium oxide, or carbon, which serve as self-aligning etch masks for creating contact holes between the conductors.
