Tuning Photoresist Adhesion with HMDS: Deep Dive into Photolithography

In the fields of semiconductor manufacturing and microfabrication, photolithography is an essential technique that creates intricate patterns on substrate surfaces. The patterning process is used frequently in electronics, microfluidics, and sensors and creates a protective layer from additional manufacturing processes and mechanical wear during its final application. To create these patterns, a mask and photoresist are applied to the substrate and exposed to light. After exposure, the photoresist is developed using a chemical solution, and the unexposed sections of the photoresist are dissolved, resulting in the desired pattern.

How HMDS is Used in Surface Science

Hexamethyldisilazane (HMDS) is a colorless, flammable liquid with a unique chemical structure. It is frequently used in surface science as a primer agent to treat the surfaces of silicon wafers and make them more suitable for adhesion with a photoresist. Using HMDS is also common as a pre- and post-treatment method for surface coating applications. In this blog post, we will look at how HMDS is used in surface science and the benefits of doing so.

Unlocking Alzheimer’s Molecular Secrets with Infrared Nanospectroscopy

Alzheimer’s disease is a devastating condition characterized by memory loss and cognitive impairment, causing immense suffering for patients and their families. One of the main causes of Alzheimer’s is the aggregation of a protein called amyloid-β (Aβ42) in the brain, leading to the formation of toxic structures. Scientists have been working tirelessly to understand the molecular basis of this disorder and develop treatments that can stop or reverse the aggregation process. In a groundbreaking study, researchers used infrared nanospectroscopy and ultra-flat gold to explore the interactions between Aβ42 aggregates and a small molecule inhibitor.

Unveiling the Secrets of Alzheimer’s Disease at the Nanoscale

Alzheimer’s disease (AD) is a debilitating neurodegenerative condition that affects millions of people worldwide. It is the leading cause of cognitive decline and death among seniors, accounting for about 70% of all neurodegenerative diseases. One of the hallmarks of AD is the accumulation of amyloid-β (Aβ) proteins, which form toxic aggregates known as amyloid plaques. To better understand the molecular mechanisms behind AD and develop effective treatments, researchers are continually exploring new techniques to study these proteins at the nanoscale.

Custom Dicing Service

Platypus Technologies offers a customizable dicing service for a range of substrate materials. Accommodations can be made for both silicon wafers and glass substrates. Substrates are scribed, and then broken into individual pieces. Well-defined scribing lines are made with a diamond finished scribing wheel. This process does not involve heat therefore prevents any potential damage to a substrate material. 

What is Plasma Cleaning?

Reactive gas molecules form what is known as plasma. The ions and electrons in plasma are used to remove unwanted organic contaminants. Unwanted particles are removed through a vacuum system. This cleaning procedure creates an ideal sterilization process. In addition, plasma cleaning eliminates the need for expensive solvents since substrate surfaces can be cleaned via a chemical reaction within plasma molecules.
