Die

For customers who want complete control over packaging and signal conditioning, SMI offers sensor die. These are typically delivered as sawn wafers on tape, but other options include picked die in waffle packs or Gel-PakTM boxes. Sensor die are fully inspected and electically probed before delivery.

 Customized die options include:

  • Backside Gold for eutectic bonding
  • Top-side Gold or Platinum for harsh media
  • Wafer Thinning for die stacking
  • Solder bumping
  • Open or closed bridge designs


Ultra Low Pressure Die (SM95D/G)
The SM9520 is a silicon micro-machined, piezoresistive pressure sensing die. This device is available with a full-scale range of 0.15 to 1.50 PSI (1.0 to 10 kPa) and is ideal for OEM and high-volume applications.

Backside Pressure Harsh Media Die (SM99A)
The SM99A is a silicon micro-machined, piezoresistive pressure-sensing chip. The SM99A is designed for harsh media where absolute pressure needs to be accurately measured. In contrast to traditional pressure-sensing chips the media only comes in contact with silicon materials. Therefore, the electronic structures on the front side of the die will not be affected during operation.
