Nitride Coated Silicon Wafers (SiN) to Fabricate BioMEMS

A research assistant from a Biosendor and BioMEMS lab requested the following quote.

We have an immediate need for a few silicon wafers with a nitride or a nitride/oxide coating for our BioMEMS project.   Probably any nitride (PECVD preferred) with a layer thickness over 2000A would do, without or without an oxide under layer, 5" or 6" diameter standard silicon, DSP or SSP, P-doped is better than N, and almost any resistance.  3 or 4 would be great, even 2 would help, we would buy a partial boat if you have one at a good price.

500nm of oxide seem to be the preferred oxide thickness for BioMEMS applications.

What Substrates are Used to Fabricate BioMEMS?

BioMEMS, which stands for Biological MicroElectroMechanical Systems, are typically fabricated using a biomems substratesvariety of substrates depending on their intended application and functionality. Common substrates used in the fabrication of BioMEMS include:

  1. Silicon: Silicon is a widely used substrate in MEMS technology due to its excellent mechanical properties, well-established fabrication processes, and compatibility with microelectronics. For BioMEMS, silicon can be used to create microstructures, sensors, and actuators.

  2. Glass: Glass is another popular substrate due to its transparency, which is advantageous for optical applications, and its biocompatibility. Glass substrates are often used in microfluidic devices and for cell culture platforms.

  3. Polymers: Various polymers are used in BioMEMS for their flexibility, biocompatibility, and ease of fabrication. Common polymers include PDMS (polydimethylsiloxane), PMMA (polymethyl methacrylate), and SU-8. These materials are particularly useful in soft lithography and for creating flexible or disposable devices.

  4. Ceramics: Certain ceramic materials are used in BioMEMS, especially for applications requiring high temperature stability or specific electrical properties. Alumina and zirconia are examples of ceramics used in some BioMEMS devices.

  5. biomeme, illustrating the fusion of biological and technological elements.

    Biodegradable Materials: For implantable or transient devices, biodegradable materials are sometimes used. These materials can degrade safely in the body after serving their purpose, minimizing the need for surgical removal.

  6. Metals: Metals like gold, platinum, and titanium are used in BioMEMS for electrodes, sensors, and other components requiring electrical conductivity and biocompatibility.

Each of these substrates offers unique properties and is chosen based on the specific requirements of the BioMEMS device, such as mechanical strength, biocompatibility, electrical properties, and compatibility with biological systems or fluids.

 

Fused Silica Substrates: Paving the Way for Advanced BioMEMS Devices in Heat-Related Health Monitoring

BioMicroElectroMechanical Systems (BioMEMS) are at the forefront of revolutionizing medical technology, and fused silica substrateshave emerged as a critical component in their fabrication. With their unique properties, these substrates are enabling the development of futuristic devices designed to alert individuals to potential heat-related health issues, including heat exhaustion and heat stroke.
