At JJM, there are three major business units, four wafer
fabrication facilities, and three assembly & test facilities.
Thyristors Business Unit
Key products are: bi-directional three-terminal AC switch called Triacs (0.6 ~ 1.6kV / 0.6 ~ 110A), uni-directional three-terminal
DC switches called SCR (0.6 ~ 2.2kV / 0.8 ~ 250A). These products are typically assembled & tested with dies soed from 4-inch
wafers, all manufactured at in-house facilities located at Qidong city.
Power Diodes & Protection Devices Business Unit
Key products are: Bridge Rectiers, Switching Diodes, Schottky Diodes/Rectiers, Fast/Super-fast/Ultra-fast/Hyper-fast
Recove Rectiers with & without Epitaxy, Small Signals BJT, SiC Rectier, Protection Devices (Zener Diode/Rectier, TVS, ESD,
SiDAC, Electrostatic/Gas Discharge Tube, Varistor, Thyristor Surge Suppressor), Thyristor/Rectier Power Modules.
MOSFET Business Unit
Key products are: silicon-based industrial & automotive grade MOSFETs built on mainstream technology platforms (planar,
trench, SGT, super-junction). They cover breakdown voltages V
BR(DSS)_Min
from -100V to 700V and are well suited to various
applications like consumer electronics, computing, industrial, and automotive. Wafer manufacturing and package assembly
facilities are IATF 16949 ceied to produce automotive-grade devices.
Wafer Fabrication Facilities
Four advanced fabrication sites manufacture wafers needed to realize the innovative power discrete semiconductor products
from the three business units. Wafers manufactured are of the following diameters: 4-inch, 5-inch, 6-inch, 8-inch (with future
expansion planned for 12-inch). Process nodes can reach 0.18μm and beyond. In addition, JJM has set up long-term strategic
relationship with OSWF (out-sourced wafer foundries) to complement our in-house manufacturing capacity. Our goal is to meet
customer demands and expectation with minimal lead time.
Assembly & Test Facilities
Three A/T facilities are established in-house to oer both through-hole and suace-mounted packages. These packages include
while not limited to the followings: SMA, SMB, SMC, SOD-series, SOT-series, SOP-series, TO-series, sawing & punch DFN-series,
CSP-series. Destined facilities are and shall be IATF 16949-ceied hence they can produce AEC-Q101 qualied automotive-grade
components. In addition, JJM has set up long-term strategic relationship with OSAT (out-sourced assembly & test vendors) to comple-
ment our in-house manufacturing capacity. Our goal is to meet customer demands and expectation with minimal lead time.
Jiangsu JieJie Microelectronics Co., Ltd.
In year 1995, Jiangsu JieJie Microelectronics Co., Ltd. (a.k.a.
JJM) was founded as a semiconductor IDM (integrated device
manufacturer) headquaered in Jiangsu province. Its operation
include research & development of silicon dies, wafer manufac-
turing, package assemblies, and testing (manufacturing,
verication, long-term qualication) of packaged devices. On
March 14, 2017, JJM was listed (stock code: 300623) on the
ChiNext board of Shenzhen Stock Exchange. JJM was awarded
the Top 10 Enterprises for Power Semiconductor Devices in
China ever since.
Currently, the main product pofolio of JJM comprises of the
following semiconductor devices: uni- & bi-directional thyris-
tors, MOSFETs of split-gate type (SGT) and of trench type and
of planar type and of super-junction type, protection devices
including electro-static devices (ESDs) with low input capaci-
tance and transient voltage suppressors (TVS) and varistors
with low junction capacitance, high-voltage diodes and recti-
ers, power transistors etc. Based on the revenue achieved in
year 2021, JJM was ranked #1 for thyristor devices in China
(replaced ~50% of the non-domestic competition) as well as #1
for thyristor devices worldwide.
Many of the JSFET® SGT-type MOSFET devices with V
BR(DSS)_Min
below 200V oer peormance similar to those from the tier-1
vendors across the world. Within JJM, there exist special teams
comprising of expes with multi-year global working experi-
ence to take care of auto-grade products and related tasks
covering: die R&D, assembly, product denition, testing, manu-
facturing, quality and application suppo. The four Product
R&D Centers at Qidong, Nantong, Wuxi and Shanghai continue
to bring in talents with experience on power semiconductors
from all over the world. Production facilities are located at
Qidong & Nantong cities of Jiangsu province, while their
mission are to achieve manufacturing excellence, localization
and full autonomy on all matters concerning power semicon-
ductor devices.
At JJM, leading processes and systems are in place to govern all
key disciplines: a) ISO 9001�2008 and IATF 16949 ceication
for quality management; b) ISO 14001�2004 ceication for
environmental management; c) ISO 45001 ceication for
occupational health and safety management; d) QC 080000
ceication for hazardous substance management. To
facilitate the global reach of customers’ products in which JJM’s
products are embedded, the relevant products from JJM are UL
ceied (e.g. high-voltage rectiers and TVS), RoHS and
REACH complaint, whichever applicable.
