  Type-II Weyl semimetal candidate MoTe$_2$, which superconducts at T_c~0.1 K,
is one of the promising candidates for realizing topological superconductivity.
However, the exceedingly low $T_c$ is associated with a small upper critical
field ($H_{c2}$), implying a fragile superconducting phase that only exists on
a small region of the $H$-$T$ phase diagram. Here, we describe a simple and
versatile approach based on the differential thermal expansion between
dissimilar materials to subject a thin single crystalline MoTe$_2$ to biaxial
strain. With this approach, we successfully enhance the $T_c$ of MoTe$_2$
five-fold and consequently expand the superconducting region on the $H$-$T$
phase diagram significantly. To demonstrate the relative ease of studying the
superconductivity in the biaxially strained MoTe$_2$, we further present the
magnetotransport data, enabling the study of the temperature-dependent $H_{c2}$
and the anisotropy of the superconducting state which would otherwise be
difficult to obtain in a free-standing MoTe$_2$. Our work shows that biaxial
strain is an effective knob to tune the electronic properties of MoTe$_2$. Due
to the simplicity of our methodology to apply biaxial strain, we anticipate its
direct applicability to a wider class of quantum materials.
