When
considering a micromachined solution for your application, the important
initial questions are (a) is the process to prepare the device feasible?
(b) are the feature size diminution, greatly increased machining
accuracy and tolerance important to the function of the device?
(c) can micromachining provide a cost effective solution (d) can
the device be satisfactorily packaged or integrated into the current
process?
Types
of Structures and Functions Available from Silicon Micromachining
Referring
to the various silicon
micromachining techniques available, the following basic
feature types can be fabricated:
· Holes: hole sizes depend on the substrate thickness
but can range from a few microns to mm;
· Depressions, wells and pits: wall slopes and well
shapes vary from vertical to round; shallow pits can be wet or dry
etched; depth:width aspect ratios of >10 are possible under some
conditions.
· Grooves and trenches: grooves with vertical or sloped
sidewalls can be etched or machined. Dimensions range from microns
to mm in width, depth and length
· Channels: bonding of a solid second wafer onto an
array of grooves generates channels
·
Membranes: Sections of the silicon wafer can be etched down
to as low as 2-4 microns to create ultra thin membranes
Silicon,
silicon microfabrication and the micromachining process have several
inherent attributes and advantages that can be very important during
the design process.
