What is MEMS Technology?

MEMS (Micro-Electro-Mechanical Systems) are tiny devices that combine mechanical and electrical components on a single silicon chip. They are made using the same semiconductor chip manufacturing process, allowing them to perform sensing, controlling, and actuating functions in compact systems.

These devices can convert electrical signals into mechanical actions or detect physical changes and turn them into electrical responses. Their structure often includes microsensors, actuators, and circuits that work together to perform precise mechanical tasks.

MEMS are produced through microfabrication techniques like photolithography and micromachining, similar to those used in Malaysia’s chip manufacturing industry. This process enables mass production of reliable, low-cost devices used in various applications such as smartphones, cars, and medical equipment.

Different Types of MEMS Devices and Usage

MEMS devices come in various forms, each serving unique functions such as sensing, actuating, or resonating to support modern electronics. These micro-scale systems take advantage of the semiconductor chip manufacturing process to achieve high precision, low power consumption, and compact size.

Below are the most common types of MEMS devices and their applications in industries like automotive, consumer electronics, and Malaysia’s chip manufacturing sector.

1. Capacitive MEMS

Capacitive MEMS work by detecting changes in capacitance between conductive plates inside the device. When pressure, acceleration, or sound waves alter the plate distance, the change is converted into an electrical signal.

This mechanism makes them ideal for sensors like accelerometers, microphones, and pressure detectors. Because they’re made using advanced semiconductor manufacturing processes, they deliver accuracy and reliability even in small-scale systems.

2. Gyroscopic MEMS

Gyroscopic MEMS measure rotational movement by comparing the inertial force of an object against a stable reference. These devices are widely used in drones, gaming controllers, and automotive stability systems.

By integrating electronic and mechanical components on one chip, they ensure smooth and accurate motion detection. Their efficiency and compactness make them a vital part of modern MEMS innovations.

3. Piezoelectric MEMS

Piezoelectric MEMS convert mechanical stress or vibration into electrical energy using the piezoelectric effect. They are often applied in ultrasonic sensors, microphones, and vibration detectors.

Their self-generating energy capability makes them useful in low-power devices and wireless sensing applications. Built with the semiconductor chip manufacturing process, these MEMS showcase the seamless fusion of mechanical motion and electrical function.

4. Laser-Based MEMS

Laser-based MEMS use micro mirrors or tunable structures to control and direct light beams. These are commonly found in optical communications, automotive lighting, and projection systems.

By adjusting laser wavelengths precisely, they enhance performance and reduce energy consumption. Such technology exemplifies how Malaysia’s chip manufacturing advances photonics innovation through MEMS integration.

5. MEMS Oscillators and RF Filters

MEMS oscillators generate stable frequency signals, replacing bulky quartz oscillators in mobile devices and communication systems. They are compact, durable, and capable of producing frequencies from a few hertz to hundreds of megahertz.

Meanwhile, MEMS-based RF filters are used for signal processing in wireless communications, offering size and cost advantages. Together, these components demonstrate how MEMS technology refines modern electronics through scalable semiconductor manufacturing solutions.

How Does MEMS Work?

MEMS function through the integration of miniaturized sensors, actuators, and processors on a single silicon chip. These components interact to sense physical changes, process data, and produce a mechanical or electrical response through precise movement.

Below are the main elements that explain how MEMS work and how they’re built using the semiconductor chip manufacturing process commonly applied in Malaysia’s chip manufacturing industry.

• Microsensors: Microsensors detect physical changes such as pressure, temperature, or acceleration and convert them into electrical signals. They act as the “eyes” of the MEMS, allowing the system to perceive and respond to its environment accurately.
• Microactuators: Microactuators convert electrical energy into mechanical motion, enabling MEMS devices to perform actions such as movement or control. They are responsible for tasks like adjusting smartphone screens, operating microvalves, or controlling light through micro-mirrors.
• Microprocessors and data units: These components serve as the “brains” of MEMS, processing data collected by sensors and sending commands to actuators. Their integration on the same silicon substrate enhances performance and minimizes power consumption.
• Fabrication and integration: MEMS are created using the Chip Manufacturing Process, similar to how integrated circuits are made. Through batch fabrication, micro-sensors and micro-actuators can be produced together, reducing cost and improving consistency across large volumes.
• Packaging and protection: Each MEMS device must be carefully packaged to prevent contamination from air or moisture while maintaining functionality. The packaging ensures electrical or optical circuits remain protected, allowing the device to move or sense effectively in various environments.

Practical applications: Everyday uses of MEMS include smartphone gyroscopes, car airbag sensors, and inkjet printer nozzles. Their small size, efficiency, and low cost make them vital to emerging technologies like IoT, healthcare, and semiconductor manufacturing innovation.
