Unwavering Wafer Stability

In the intricate world of semiconductor processing, wafers are subject to various steps and maneuvers. To maintain the utmost precision and consistency, wafers must stay firmly in place. Our Vented Hole Heater Chuck employs vacuum holes that generate a powerful suction force, keeping your wafer securely affixed to the chuck's surface. This means no more worries about unwanted movement or misalignment during processing, translating to precise, reliable results every time.

Eliminating Air and Gas Imperfections

Wafer surfaces and chucks, while engineered with the utmost care, may not always be perfectly flat or smooth. Microscopic imperfections, particles, or trapped air between the wafer and the chuck can spell trouble for the quality of your processes. BCE's Vented Hole Heater Chuck comes to the rescue by providing a channel for the escape of trapped air and gas. This ensures optimal contact between the wafer and the chuck, enhancing adhesion and minimizing any reduction in quality.

Optimized Heat Transfer

In critical processes such as wafer bonding and thin-film deposition, precise temperature control is paramount. The Vented Hole Heater Chuck excels in this regard as well. By ensuring improved and uniform contact between the wafer and the chuck, it facilitates efficient heat transfer. This is a fundamental requirement for semiconductor processes, where temperature control can make or break your desired outcome.

Defying Contaminants

The Vented Hole Heater Chuck doesn't stop at just securing your wafer; it also takes an active stance against contaminants. In semiconductor environments, even the tiniest particles, like dust or debris, can compromise the end product. Our vented vacuum holes act as a barrier, preventing the entrapment of such contaminants between the wafer and the chuck. This significantly boosts the cleanliness of your process, reducing the risk of defects or contamination on the wafer's surface.

BCE's Vented Hole Heater Chuck is your trusted partner in the semiconductor industry, offering rock-solid stability, impeccable heat transfer, and stringent contamination prevention. With this 4" wafer heater chuck, you can maintain a secure connection between your wafer and the chuck while ensuring the removal of air and gas, all in the pursuit of top-tier precision and quality.

HEM Sealed Heater™ - Bench Test to 250°C

HEM Sealed Heater

In addition to optimizing liquid flow in space launches, more research and design facilities require a heater that will work in vacuum without outgassing the internal resistor and insulating materials.  Materials such as chromium and particles from the magnesium oxide begin to outgas.  Placing a vacuum barrier that keeps these particles in place and allows the operator to process without consistently replacing heaters, should increase productivity.

HEM Sealed Heater™/ Vacuum Chambers:
  • Temperature range of -55⁰C to +200⁰C Sheath Temperatures
  • Stainless steel 321 for heated zone, 304 Hem Sealed Cap   
  • 18AWG to 32AWG Kapton®/polyimide Lead wires 
  • 500Watt (± 10%) , 240 Volt, 1-phase   
  • He Leak Tested = 5 x 10¯⁹ ATM, CC/sec or better 
  • Hi-Pot Test 1K*2E 1 2 seconds (1500-2250VDC 0.5mA) 
  • Meg-Ohm 20 to 4,000+ @ 500VDC 


This test was performed in atmosphere within a 3.5 hour time frame.  The temperature was held each hour after the initial ramp to sheath temperature as noted in the graph below.

The temperature of 200°C was held for the 2nd hour and then the heater was powered ~250°C and held until the test was complete after about 3.5 hours.  

At lower temperatures of ~200°C, the Hem Sealed™ Cap reached 60°C keeping the vacuum integrity as per the maximum heater transition temp of 70°C.  The maximum temperature on the sheath tested was to 250°C with the Hem Sealed™ Cap at 79°C.

Special note; if a heater block or other device being heated, the optimal bore diameter vs heater diameter for the best heat transfer should be +.0020” to +.0025”.

The Role of Vacuum Feedthroughs

The Role of Vacuum Feedthroughs in High Vacuum Applications

Vacuum feedthroughs are devices that are used to allow electrical, optical, or fluid connections to pass through a vacuum chamber wall. They are essential in high vacuum applications because they allow for the passage of electrical power, control signals, and other types of data into and out of the vacuum chamber while maintaining the integrity of the vacuum.

There are several reasons why vacuum feedthroughs are important in high vacuum applications. First and foremost, they allow for the passage of electrical power and control signals into the vacuum chamber, which is necessary for operating many types of equipment and instruments that are used in high vacuum environments. For example, electrical feedthroughs can be used to power a vacuum pump, while optical feedthroughs can be used to transmit data from sensors or cameras that are located inside the vacuum chamber.

In addition to electrical and optical connections, vacuum feedthroughs can also be used to transport fluids, such as coolants or process gases, into or out of the vacuum chamber. This is particularly important for applications that require temperature control or precise gas delivery, such as in the case of thin film deposition or material processing.

Another important aspect of vacuum feedthroughs is that they can be designed to minimize the amount of outgassing that occurs, which is the release of gas from the feedthrough material into the vacuum chamber. This is important because outgassing can contaminate the vacuum environment, potentially causing damage to the equipment or samples inside the chamber.

Lastly, vacuum feedthroughs must be designed to withstand the high vacuum conditions and operate efficiently and reliably. These feedthroughs typically consist of a metal or ceramic stem with an epoxy, glass or ceramic seal that allows the electrical, optical, or fluid connection to pass through the vacuum chamber wall. The feedthrough stem must be sealed to the vacuum chamber wall without leaking, while the electrical, optical, or fluid connections must maintain their integrity under the high vacuum conditions.

In summary, vacuum feedthroughs play a crucial role in high vacuum applications, by allowing electrical, optical, or fluid connections to pass through the vacuum chamber wall while preserving the high vacuum condition. They also play a important role in controlling temperature, providing gases and maintain the integrity of the electrical, optical and fluid connections.
