45V 200MHz Analog Bipolar PROCESS
HTE Labs
STANDARD PROCESS OVERVIEW
The standard 45V 200MHz analog bipolar process employs N type silicon epitaxial layer on P type silicon substrate. In the standard process up to 8 masks are used: - buried layer (sub collector), isolation, base, emitter, contact mask, thin film resistor mask, metal mask, pad mask. The devices available are vertical NPN transistors, vertical substrate PNP transistors, lateral PNP transistors, TaN2 - tantalum nitride thin film resistors and MNOS MOS (metal oxide semiconductor) capacitors.
PROCESS OPTIONS
Process enhancements are added to increase the integrated circuit designer's flexibility in designing with HTE Labs analog bipolar process. Optional devices available are as follows: P JFET (p channel junction field effect transistor), EPI N JFET (n channel silicon epitaxial junction field effect transistor), Schottky diodes,Varactor diodes, PIN diodes,Zenner diodes, laser trim able NiCr (nickel chrome resistors) , TaN2 (tantalum nitride resistors) or SiCr (silicon chrome resistors) sputtered thin film resistors. Sheet resistance for the integrated thin film resistors is offered in the widest range from 1? / square to 100k ? / square while the temperature coefficient of resistance is between ±25 ppm/°C to ±500ppm/°C.
For metal interconnections HTE Labs process employs up to two layers of metallization, TiW/Au (standard metallization). The interlayer dielectric is 1µm SiO2 while the passivation is Si3N4 or SiO2. Minimum contact size is 3µm x 3µm while the metal pitch is 10µm. For flip chip, chip on board and chip scale packaging applications, Gold bumps or solder bumps are available process options. The 45V 200MHz custom analog bipolar process employs up to 12 masking layers for all features to be included. What sets HTE Labs apart are couple main process options and capabilities that are not typically acceptable or handled by large wafer foundries.
* Custom developed processes
Custom developed processesHTE Labs has the engineering resources and processing capabilities to develop custom processes to fit customer's specific applications. This capability is offered to customers on a contract base only.
* High stability thin film resistors
High stability thin film resistors with sheet resistance as high as 100K?/square. The matching of the as deposited thin film resistors is excellent with ought expensive laser trim. The absolute values of resistors are within ± 5% across the wafer and from wafer to wafer. For high speed RF IC process applications, thin film resistors are best suited due to their very low capacitance and low noise.
* High reliability gold metal interconnections
High reliability gold metal interconnections is a standard process feature specifically designed for hybrid circuits applications, chip on board applications and sensors that need to withstand corrosive environment where aluminum or copper metallization are not a suitable choices.
* Process enhancements
MEMS smart sensor integration KOH anisotropic etch, deep RIE etch, LPCVD polysilicon and front to back mask alignment are few process enhancements that are needed in developing and manufacturing of integrated smart pressure sensors, accelerometers and other as such.
* Optoelectronics
Optoelectronic integrated circuits Photo transistors, photodiodes and low capacitance high speed PIN diodes, when integrated with the bipolar process, allow increased flexibility to design and manufacturing of fiber optic amplifiers, optocouplers or optical switches.
