MATECH Consulting and Services Division

Providing Consulting, Product and Process Development Services to our Customers for over 10 years

The following is a representative—but not all-inclusive—outline of the services and expertise that MATECH places at the disposal of its customers. It is intended to serve as a basis for our customers to assess our suitability to become part of their solutions team and a resource onto which to draw upon for its materials process and product development needs.

 

SERVICES AND TECHNOLOGIES OUTLINE

Silicon etching

Isotropic etching (HF-based chemistries) for membrane formation, stress relief, surface damage removal, and for many other applications.

Anisotropic etching (KOH, EDP, Ethanolamine, TMAH, hydroxide and other specialty chemistries) for MEMS and microsystems fabrication, membrane fabrication, device patterning, gratings, optoelectronic and optical applications, among others.

Substrates and parts of up to 18” in diameter, or larger by special arrangements.

Glass and quartz etching

HF-based etching and thinning of glass and quartz substrates and parts for stress relief, surface damage relief, surface modification, among others.


Chemical glass machining. Near net shape formation of glass or quartz optics and other materials. This technology avoids machining and the encompassing surface damage. It can also be faster and more economical than conventional grinding.

Substrates and parts of up to 18” in diameter, or larger by special arrangements.

Thinning

Silicon substrate thinning down to 50um (down to 10um in some cases) with our WaveEtch™ systems. Please refer to our WaveEtch web page for process and substrate specifications.


Thinning is done single sided, so devices or features on the non-process side are untouched during the process. Thinning can be done as a last step before packaging. Application examples are CCDs, focal plane arrays, memory, high frequency-high power devices, among others.


Wafers and substrates up to 8” in diameter can now be handled, with 12” capability to be announced in the near future.

Glass, quartz, and other materials can also be thinned

Patterning

Single sided Silicon, InP, GaAs, InGaAs, glass, quartz wet etch patterning

Conventional immersion etching also available for patterning applications.

Form mesa etch, vias, trench, gratings, MEMS, etc.

Membrane etching

Freestanding formation of membranes in many materials, such as SiC, SiN, AlGaN, GaN, diamond, dimond-like carbon (DLC), and many others.

Both isotropic single sided etching (See Chandra below) where only one side of the substrate is exposed to the chemicals, or conventional anisotropic immersion etching are available for membrane and free standing thin film structures fabrication.

See NASA’s Chandra in our news page, or visit NASA's Chandra web page. All of its gratings were fabricated with one of our RotoEtch™ systems by MIT’s Space Nanotechnology Laboratory under contract by NASA.

Photo and Electro-chemical etching of silicon

Advanced etching processes for demanding applications. Please contact us to discuss your needs.


These process open the door for the fabrication of unconventional structures or structures by unconventional means. Mechanical machining can be avoided in the fabrication of intricate Si parts and all-chemical net shape fabrication is possible.

Silicon reference standards for metrology and optical applications

Wafers with very accurate and precise holes and other features, etched glass structures, among others are parts that MATECH fabricates or can develop the processes for our customer’s in hose manufacture.

Consulting and Process Development

MATECH has over 10 years of experience using the processes outlined above, developing and tailoring them to specific customer fabrication needs. MATECH can also integrate the above with other related processes such as lithography, dry etching, and deposition, among other, to become part of an integrated solution for our customers.

Automation and Control Systems

MATECH Automation and Control Group can develop, consult for, or assist our customers in designing, prototyping, and manufacturing automation and electronic control systems. MATECH can design, re-design, modernize (i.e. SMT, microprocessor-based controllers, etc.), update and manufacture custom control and automation systems for all classes of processes, systems and applications.

From cost effective printed circuit board design and manufacture to full system design, build and integration. Please contact MATECH to discuss your requirements.

Other Services

A variety of services and structures can be provided for the device, optoelectronic, optics, MEMS, and microfabrication communities which fall well within MATECH’s area of expertise and are too many to explicitly enumerate above. Please call with your requirements and we will be glad to discuss them with you.
