Thin-Film Technology

THE IDEAL CAPACITOR

The non-ideal characteristics of a real capacitor can be

ignored at low frequencies. Physical size imparts inductance

to the capacitor and dielectric and metal electrodes result in

resistive losses, but these often are of negligible effect on the

circuit. At the very high frequencies of radio communication

(>100MHz) and satellite systems (>1GHz), these effects

become important. Recognizing that a real capacitor will

exhibit inductive and resistive impedances in addition to

capacitance, the ideal capacitor for these high frequencies is

an ultra low loss component which can be fully characterized

in all parameters with total repeatability from unit to unit.

Until recently, most high frequency/microwave capacitors

were based on fired-ceramic (porcelain) technology. Layers

of ceramic dielectric material and metal alloy electrode paste

are interleaved and then sintered in a high temperature oven.

This technology exhibits component variability in dielectric

quality (losses, dielectric constant and insulation resistance),

variability in electrode conductivity and variability in physical

size (affecting inductance). An alternate thin-film technology

has been developed which virtually eliminates these vari-

ances. It is this technology which has been fully incorporated

into Accu-F

and Accu-P

to provide high frequency capaci-

tors exhibiting truly ideal characteristics.

The main features of Accu-F

and Accu-P

may be summa-

rized as follows:

• High purity of electrodes for very low and repeatable

ESR.

• Highly pure, low-K dielectric for high breakdown field,

high insulation resistance and low losses to frequencies

above 40GHz.

• Very tight dimensional control for uniform inductance,

unit to unit.

• Very tight capacitance tolerances for high frequency

signal applications.

This accuracy sets apart these Thin-Film capacitors from

ceramic capacitors so that the term Accu has been

employed as the designation for this series of devices, an

abbreviation for “accurate.”

THIN-FILM TECHNOLOGY

Thin-film technology is commonly used in producing semi-

conductor devices. In the last two decades, this technology

has developed tremendously, both in performance and in

process control. Today’s techniques enable line definitions of

below 1µm, and the controlling of thickness of layers at 100Å

(10

-2

µm). Applying this technology to the manufacture of

capacitors has enabled the development of components

where both electrical and physical properties can be tightly

controlled.

The thin-film production facilities at AVX consist of:

• Class 1000 clean rooms, with working areas under

laminar-flow hoods of class 100, (below 100 particles

per cubic foot larger than 0.5µm).

• High vacuum metal deposition systems for high-purity

electrode construction.

• Photolithography equipment for line definition down to

2.0µm accuracy.

• Plasma-enhanced CVD for various dielectric deposi-

tions (CVD=Chemical Vapor Deposition).

• High accuracy, microprocessor-controlled dicing saws

for chip separation.

• High speed, high accuracy sorting to ensure strict

tolerance adherence.

Thin-Film Chip Capacitors

ACCU-F

TECHNOLOGY

The use of very low-loss dielectric materials, silicon dioxide

and silicon oxynitride, in conjunction with highly conductive

electrode metals results in low ESR and high Q. These

high-frequency characteristics change at a slower rate with

increasing frequency than for ceramic microwave capacitors.

Because of the thin-film technology, the above-mentioned

frequency characteristics are obtained without significant

compromise of properties required for surface mounting.

The main Accu-F

properties are:

• Internationally agreed sizes with excellent dimensional

control.

• Small size chip capacitors (0603) are available.

• Tight capacitance tolerances.

• Low ESR at VHF, UHF and microwave frequencies.

• High stability with respect to time, temperature, frequency

and voltage variation.

• Nickel/solder-coated terminations to provide excellent

solderability and leach resistance.

ACCU-P

TECHNOLOGY

As in the Accu-F

series the use of very low-loss dielectric

materials (silicon dioxide and silicon oxynitride) in conjunction

with highly conductive electrode metals results in low ESR and

high Q. At high frequency these characteristics change at

a slower rate with increasing frequency than conventional

ceramic microwave capacitors. Using thin-film technology, the

above-mentioned frequency characteristics are obtained with-

out significant compromise of properties required for surface

mounting. The use of high thermal conductivity materials

results in excellent RF power handling capabilities.

The main Accu-P

properties are:

• Enhanced RF power handling capability.

• Improved mechanical characteristics.

• Internationally agreed sizes with excellent dimensional control.

• Ultra Small size chip capacitors (0201) are available.

• Tight capacitance tolerances.

• Low ESR at UHF, VHF, and microwave frequencies.

• High-stability with respect to time, temperature, frequency

and voltage variation.

• High temperature nickel/solder-coated terminations as stan-

dard to provide excellent solderability and leach resistance.

ACCU-F

FEATURES

Accu-F

meets the fast-growing demand for low-loss

(high-Q) capacitors for use in surface mount technology espe-

cially for the mobile communications market, such as cellular

radio of 450 and 900 MHz, UHF walkie-talkies, UHF cordless

telephones to 2.3 GHz, low noise blocks at 11-12.5 GHz and

for other VHF, UHF and microwave applications.

Accu-F

is currently unique in its ability to offer very

low capacitance values (0.1pF) and very tight capacitance

tolerances (±0.05pF). Typically Accu-F

will be used in small

signal applications in VCO’s, matching networks, filters, etc.

Inspection test and quality control procedures in accordance

with ISO 9001, CECC, IECQ and USA MIL Standards yield

products of the highest quality.

ACCU-P

FEATURES

• Minimal batch to batch variability of parameters at high fre-

quency.

• The Accu-P

has the same unique features as the Accu-F

capacitor such as low ESR, high Q, availability of very low

capacitance values and very tight capacitance tolerances.

• The RF power handling capability of the Accu-P

allows for

its usage in both small signal and RF power applications.

• Inspection, test and quality control procedures in accor-

dance with ISO 9001, CECC, IECQ and USA MIL Standards

guarantee product of the highest quality.

• Hand soldering Accu-P

: Due to their construction

utilizing relatively high thermal conductivity materials,

Accu-P’s have become the preferred device in R & D labs

and production environments where hand soldering is used.

Accu-P’s are available in all sizes and are electrically identi-

cal to their Accu-F counterparts.
