Solid State Batteries
Cymbet Corporation is the leader in solid-state energy storage solutions for microelectronic systems. The company is the first to market eco-friendly rechargeable solid-state batteries that provide electronic systems designers with new embedded power capabilities. The company's EnerChip™ devices enable new concepts in energy storage application for ICs and new products for medical, sensor, RFID, industrial control, communications and portable electronic devices.
EnerChip™ Bare Die Enable Embedded Energy
Cymbet EnerChip™ rechargeable solid-state energy storage devices are created using semiconductor processing techniques on silicon wafers. EnerChip™ devices are compatible with other semiconductor integrated circuits and passive devices and can be co-packaged together. EnerChip™ devices as small as 1mm x 1mm can be coupled with other ICs to create unique innovative products such as the millimeter scale solar Energy Harvesting-based sensor shown below. (The 12uAh EnerChip™ bare die is the bottom layer.)
EnerChip Bare Die Attachment Mechanisms
Since EnerChip™ devices are produced like semiconductor devices, they are packaged in the same fashion as other ICs. EnerChip™ bare die lead attachment may be accomplished with either wire bond or solder bump techniques. EnerChip™ bare die may be processed with solder bumps on the attach pads. Bumped EnerChip™ bare die can then be attached in the package as shown in the following diagram.
EnerChip CC Uses an Embedded Energy Co-Package
Given the unique structure of EnerChip™ devices, there are several ways to mount and attach the EnerChip™ bare die. The traditional method of wire bonding is what Cymbet utilizes in standard EnerChip™ packaged offerings as it is very reliable and cost effective. Wire bond techniques are shown in the following diagrams in two configurations: Side by Side, or Stacked Die.
New Embedded Energy Applications
EnerChip™ rechargeable solid-state energy storage devices are designed for direct integration at the chip level, or as an SMT component replacing current coin cell battery or supercapacitor products. The EnerChip™ can provide back-up power and energy management functions in a single co-package providing a simple “drop in power” solution with up to 8 weeks of permanent back-up power.
Embedded Energy is useful in many industries:
- Consumer Electronics
- Industrial Controls
- Medical Devices
- Environmental Sensors
- Hand-held Devices
- Networking and Communication Systems
- Security and Tamper Detection
- Military and Aerospace
