Stephen J. Pearton, an accomplished inventor based in Summit, NJ, has contributed significantly to the field of materials science and semiconductor technology. With a total of five patents to his name, Pearton has made innovative strides in the method of growing aluminum and gallium-containing layers, impacting various manufacturing processes.

Latest Patents

Pearton's recent innovations include two pivotal patents that focus on methods for selectively growing aluminum and gallium-containing layers:

1. **Method for Selectively Growing Aluminum-Containing Layers** - This invention involves the use of molecular beam processes wherein phenylarsine (PhAs) serves as an arsenic precursor. Due to its unique reactivity, PhAs selectively decomposes on III-V surfaces while avoiding unwanted growth on typical masking materials. This method allows for selective growth on unmasked gallium arsenide surfaces, optimizing production efficiency.

2. **Method for Selectively Growing Gallium-Containing Layers** - Pearton's second patent utilizes a compound from the dialkylaminoarsenic family (DAAAs), such as tris-dimethylamino arsenic (DMAAs), as an arsenic source. This innovative approach acts as a carbon 'getter,' effectively removing carbon impurities from the gallium source and enabling the selective growth of high purity or n-type layers of gallium arsenide at temperatures below 600°C. Additionally, DMAAs has proven to be an effective cleaning agent for gallium arsenide materials, enhancing overall quality.
